8-Inch Showdown: NexStar 8SE vs Apertura AD8 vs eVscope 2 – Classic Telescopes Battle Smart Tech in 2025

Three popular telescopes – Celestron’s NexStar 8SE, Apertura AD8 Dobsonian, and Unistellar’s eVscope 2 – offer very different paths to the stars. The NexStar 8SE is a computerized 8-inch Schmidt-Cassegrain, the Apertura AD8 is a manual 8-inch Dobsonian reflector, and the eVscope 2 is a 4.5-inch “smart” telescope with built-in imaging. All three can reveal the cosmos, but they differ in optics, technology, and user experience. In this comparison, we’ll explore optical performance, mounts and tracking, smart features, astrophotography, portability, setup, user experience, and maintenance for each scope. We’ll also include expert opinions, the latest updates (as of August 2025), and what’s next from Celestron, Apertura, and Unistellar. Let’s see which telescope shines for your stargazing needs!

Optical Performance

Aperture & Optics: The Celestron NexStar 8SE and Apertura AD8 both boast 8-inch (203 mm) primary mirrors, giving them similar light-gathering power. The NexStar 8SE’s Schmidt-Cassegrain optics have a long 2032 mm focal length (f/10), while the AD8’s Newtonian mirror is ~1200 mm focal (f/5.9). In practice, both 8-inch scopes deliver bright views of the Moon, planets, and many deep-sky objects. Reviewers note that the views through an 8″ SCT or 8″ Dob are comparable in brightness and detail. “The NexStar 8SE…gives similar views to vastly less expensive 8” Dobsonians,” writes one expert, though he adds the 8SE lacks the wide field of view and stability that make Dobs popular. The AD8’s shorter focal ratio means it can achieve lower magnifications for wide-field views of star clusters and nebulae that “can’t be beat by any other alternatives” in its class. In contrast, the 8SE’s narrower field is better for small targets like planets and planetary nebulae, but it can’t natively capture wide swaths of sky.

Image Sharpness & Contrast: Both the 8SE and AD8, if well collimated, offer sharp optics. The NexStar’s 8-inch Schmidt-Cassegrain (C8) design has been refined over decades – “Celestron has been producing C8s in basically the same format…still essentially the same scope nearly forty years later” and optically pretty good. Space.com’s testing was “seriously impressed by its optical prowess”, reporting “consistently bright and sharp views across a range of different targets” space.com. The AD8’s parabolic mirror likewise provides crisp images; its optics earned a perfect 5/5 score in one review. With the AD8’s slightly smaller secondary mirror obstruction, it can deliver a bit more contrast on faint details than the 8SE, but both scopes can resolve Saturn’s rings, Jupiter’s cloud bands, and hundreds of deep-sky objects under dark skies. One difference is edge-of-field distortion: the f/5.9 Dobsonian may show some coma (blurring of stars at the edge), whereas the f/10 SCT has a flatter field but a narrower true field. For most amateur use, both perform excellently in the center of the view.

Unistellar eVscope 2’s Optics: The eVscope 2 has a much smaller 4.5-inch (114 mm) mirror (f/3.9, 450 mm focal length). In pure aperture, it gathers only about 1/4 the light of the 8-inch scopes. Visually, a 4.5″ mirror can show the basics of the Moon and planets (limited detail on Jupiter/Saturn) and some bright deep-sky objects as faint smudges. However, the eVscope isn’t used like a traditional visual telescope – it’s essentially a digital astrophotography device that stacks images in real time. Thanks to its 7.7 megapixel sensor and “enhanced vision” software, the eVscope 2 can reveal surprisingly rich detail in faint objects by accumulating light over time. For example, under a city sky where the 8SE or AD8 might only glimpse a gray blur of the Whirlpool Galaxy (M51), the eVscope’s live-stacking will display the galaxy’s spiral arms in color after a few minutes. One reviewer marveled that “even in the middle of a city the eVscope 2 is capable of revealing hidden stars in the night sky only usually visible in very dark sky locations” livescience.com. This electronic boost lets a 4.5″ scope outperform what the eye could see through a much larger telescope on deep-sky objects. The trade-off is resolution – the eVscope 2’s views (on its screen/eyepiece) are essentially digital images limited by the small 114 mm optics and 7.7MP sensor. Tiny features like craters smaller than a few kilometers, or fine planetary details, won’t be as sharp as through an 8″ scope with a high-power eyepiece on a perfect night. In fact, some astronomers note that telescopes costing a fraction of the eVscope 2 can outperform it for lunar and planetary viewing. The eVscope’s strength is showing colorful deep-sky views easily, not high-resolution visual observation.

Collimation & Alignment: Both the NexStar 8SE and Apertura AD8 require occasional collimation (alignment of their mirrors) to perform optimally. The AD8’s open-tube Newtonian design may need tweaking every few sessions, especially after transporting – fortunately it has accessible knobs and even includes a laser collimator tool (though one review quips the included laser is “not really useful out of the box”). The 8SE’s closed Schmidt-Cass optics hold collimation longer, but when needed, adjusting the secondary mirror can be “tedious as with any Schmidt-Cassegrain”, often done on a star at high magnification. (Many users install “Bob’s Knobs” thumbscrews to make 8SE collimation easier.) The eVscope 2 comes pre-aligned; Unistellar uses factory collimation (in fact, the newer models involve Nikon’s precision alignment). Users rarely need to collimate the eVscope unless it’s been jarred – and there are procedures if needed – but generally it’s maintenance-free in that regard. In summary, optically all three can provide rewarding views, but the 8-inch scopes excel at raw detail and brightness for visual use, whereas the eVscope 2 leverages technology to show a deeper (if digital) view especially for faint DSOs, despite its smaller aperture.

Mount and Tracking Features

Celestron NexStar 8SE: The 8SE uses a motorized single-fork alt-azimuth mount with GoTo tracking. After alignment, the mount will automatically slew to targets and track their motion, keeping objects centered for visual observing. The tracking is quite accurate – reviewers found “slewing and object tracking to be incredibly accurate” in the 8SE space.com. This makes high-power observing much easier, since you don’t have to nudge the scope as objects drift. However, the 8SE’s mount is a known weak point for stability. It’s somewhat under-sized for the 8″ optical tube’s weight and length. As one expert put it, the 8SE is “a pairing of a decent mount and a decent scope, but the two have a somewhat incompatible relationship”. Vibrations can occur when focusing or in windy conditions; it’s not the steadiest setup for photography or very high magnifications. Many users add vibration suppression pads or focus motor attachments to mitigate shakes. The mount’s aluminum tripod is light and portable, but again not rock-solid. In contrast, the Apertura AD8 Dobsonian has a very sturdy mount: a simple wooden alt-az rocker box with Teflon bearings. It earned 5/5 for mount stability – visually, the Dobsonian base is ultra-steady (no jitters when you turn the knobs on the dual-speed focuser). The catch: the AD8’s mount is manual. There are no motors – you must push the tube by hand to aim and track. Smooth bearings and tension springs make this easier, but at high magnification planets will drift out of view in ~10–20 seconds, requiring frequent nudges. For short glimpses this is fine, but prolonged high-power study or sharing the view with others can be tricky without tracking. Some AD8 owners eventually add digital setting circles or an equatorial platform for tracking, but those are add-ons beyond the stock scope.

The Unistellar eVscope 2 comes on an integrated motorized alt-az mount (a compact fork on a tripod) which automatically finds and tracks objects via its computer control. Like the 8SE, it will keep objects centered, but the eVscope goes further: it platesolves the sky with its camera to align itself in minutes. There’s no need to manually center alignment stars – the scope recognizes star patterns on its own. The tracking is sufficiently precise to keep objects in the field for long observing sessions and to enable the long exposure stacking (typically the eVscope takes many 4-second exposures and stacks them). Because exposures are short, field rotation from the alt-az mount isn’t a big issue for its imaging; the software de-rotates images in stacking. The mount’s capacity is tuned just for the small 4.5″ tube, so it’s very lightweight (~20 lbs total) and portable. Despite the plastic and aluminum construction, users generally report it’s stable for the small loads – you won’t see much vibration on the app’s image. In essence, the eVscope’s mount gives GoTo convenience similar to the NexStar, but in a more compact package. It does lack the heft and potential to carry other telescopes (unlike the NexStar’s standard Vixen dovetail, the eVscope’s OTA isn’t interchangeable). One thing to note is the slew speed and noise: both the 8SE and eVscope’s motors emit a noticeable whir when slewing at full speed, but are quiet when tracking. The AD8 of course is silent and moves as fast as you push it.

Field rotation & long tracking: Because both the 8SE and eVscope 2 use alt-az mounts without field de-rotators, they are not ideal for very long single exposures in astrophotography (more on that later). But for visual tracking and short exposure stacking, they work excellently. Space.com even noted the 8SE’s smooth tracking could make it suitable for long exposure astrophotography space.com – though in reality most 8SE users doing long exposures invest in a wedge or different mount. In pure tracking terms, all three telescopes can follow objects for hours (the manual Dob can too, if you’re willing to keep nudging). But only the 8SE and eVscope relieve the user from that effort, which is a huge benefit when observing at high power or when sharing the view. It’s worth mentioning power: the 8SE’s motors require a power supply (8 AA batteries or an external 12V source). It’s notorious for quickly draining AAs – one guide “recommends using it with mains power” to avoid slewing slowdown space.com space.com. The eVscope 2 has a built-in rechargeable battery (~5 hours), so it’s cable-free in the field. The AD8 of course needs no power at all (except a small battery for its cooling fan).

In summary, if you want automated pointing and tracking, the NexStar 8SE and Unistellar eVscope 2 both deliver, with the eVscope being more advanced in self-aligning. The 8SE’s mount carries a heavier optical tube but is a bit shakier. The Apertura AD8’s mount is rock-solid and intuitive, but completely manual – a trade-off of technology vs stability. As one expert said about the 8SE, “not the steadiest mount”, whereas the AD8 is praised as “the best value 8″ Dobsonian…an outstanding value” with a smooth, stable mount.

Software and Smart Features

Celestron NexStar 8SE: As a product dating back to the 2000s, the NexStar 8SE’s “smart” features are basic by today’s standards – but still effective. It has a hand-held computer (NexStar+) with a database of ~40,000 objects. You align the scope by centering a few bright stars (or using Celestron’s SkyAlign which picks any three bright points). Once aligned, you can scroll through tours, search objects by name, or enter celestial coordinates, and the mount will go there. It’s a proven system, though a bit old-school with its two-line LCD screen and directional buttons. Many users love the independence from phones or laptops – the 8SE does not require any external device or internet. However, Celestron now offers optional upgrades: you can plug in a WiFi module and control the 8SE via the SkyPortal mobile app or PC software (CPWI). There’s also the StarSense AutoAlign accessory, a camera that automates alignment (similar to how eVscope does). Out of the box, though, the 8SE’s tech is limited to GoTo and tracking – it doesn’t have cameras or fancy processing. Some find the alignment step a minor chore, especially if you’re not familiar with the night sky. As one reviewer wryly noted, “if you don’t mind the tediousness of aligning a GoTo system…and collimating, the 8SE is for you”. That said, the alignment takes only a few minutes if you have a clear view of the sky, and thereafter the GoTo is quite user-friendly. The hand controller can be less intuitive than modern touch apps, but it’s reliable (and works in the cold with gloves, unlike touchscreens). In 2025, the NexStar 8SE remains a bit “aging” in tech interface, yet it’s still one of the best-selling telescope packages of all time (often praised for making finding objects easier for beginners).

Apertura AD8 Dobsonian: The AD8 is a fully manual, non-electronic telescope – deliberately devoid of software. Its “features” are high-quality hardware: a dual-speed focuser, a 9×50 finderscope, a cooling fan, and included accessories. There is no tracking, no object database, and certainly no app connectivity. For some hobbyists, this simplicity is a feature in itself: nothing to update, no batteries to charge (aside from that fan), and a chance to learn the night sky by star-hopping. Beginners using a Dobsonian often rely on star charts or mobile apps (like SkySafari) held separately to locate targets, or they may install analog setting circles. High Point Scientific (the distributor of Apertura) even introduced an upgrade kit with digital encoders and other tweaks to help Dob users spend “less time worrying about collimation or stray light” and more time observing. But fundamentally, the AD8 offers zero “smart” features out of the box. This means a newcomer must develop some skill at finding objects manually. It can be fun and rewarding – many astronomy educators note that using a star map to hunt down a galaxy teaches the sky in ways hitting “GoTo” does not. On the flip side, some casual users might get frustrated when they can’t easily locate faint nebulas without guidance. In 2025, even Dobsonians are seeing tech creep in (Celestron’s StarSense Dobsonians use a smartphone to guide pushes), but the Apertura AD8 sticks to the classic formula: it’s “unplugged” astronomy.

Unistellar eVscope 2: This telescope is all about smart features. The eVscope 2 is essentially a telescope + camera + computer integrated, controlled by the Unistellar smartphone app (iOS/Android). There is no optical finder or traditional eyepiece (though it has an electronic OLED eyepiece by Nikon for a simulated eyepiece view). When you power it on, the eVscope 2 uses its camera to autonomously align by plate-solving the star field – no input needed from the user besides tapping “align” in the app. In a minute or two, it’s ready to GoTo any object you select in the app’s catalog. The app provides a graphical interface with thousands of objects (and regular updates add more). Once you select, the scope slews there and begins its “Enhanced Vision” live stacking. The result is that after 10–30 seconds you start seeing a faint object appear on your screen, and over a few minutes it becomes brighter and more detailed as exposures stack. This is a transformative feature for urban stargazers: objects invisible to the eye in a light-polluted sky become visible. As LiveScience put it, the eVscope 2 offers “instant access to the cosmos” for newcomers – no complex setup. The app’s UI is simple and intuitive, and the whole experience feels very futuristic. You can observe from your backyard while the images display on a tablet or even cast to a TV, effectively turning stargazing into a group experience. The eVscope also has a “Citizen Science” mode: Unistellar partners with institutions (like SETI Institute) to have users observe asteroid occultations, comet outbursts, exoplanet transits, etc., contributing data. Hundreds of eVscope users have participated in such campaigns, with results published in scientific papers. This is a unique, interactive social aspect of the eVscope – you get notifications of upcoming events and can join with a tap.

However, the eVscope’s heavy reliance on software has downsides. First, it is entirely dependent on the app and internal computer. If the app crashes or firmware glitches, you can’t just revert to manual use. (Unistellar provides frequent software updates – e.g. a “Vivid Vision” update in late 2024 improved image processing, and as of mid-2025 version 4.1 firmware adds further stability.) Users must occasionally update the scope via the app; some have reported frustration with mandatory updates starting while in the field, though you can turn off auto-update. Also, because the eVscope is showing you a processed image, some traditionalists argue “you’re not ‘viewing’ anything – to experience real photons…you’d have to cut the camera out”. The eVscope’s marketing of “21st-century telescope” has even drawn ire from veteran astronomers who feel it overhypes what is essentially a small scope with a camera. One expert went as far as calling it “a highly deceptive product…not particularly innovative or capable” beyond a nicer sensor and app. For tech-savvy users, though, the capability to share images instantly, save them to your phone, and avoid any manual sky navigation is a huge plus. You can literally have never used a telescope before, and on night one see dozens of galaxies with ease. The eVscope 2’s “smart” package is arguably its main selling point – it’s like the “future of telescopes” in preview, trading hands-on observing for a high-tech experience.

In summary, regarding software: the 8SE has basic but time-tested GoTo firmware, the AD8 has none, and the eVscope 2 is packed with cutting-edge software (auto-align, live stacking, remote viewing) that makes astronomy plug-and-play. It just depends if you want a screen-driven experience or a more traditional one. As Celestron itself acknowledges with its new products, there’s an audience for both – but more on that in the upcoming models section.

Astrophotography Capabilities

If your goal is to capture photographs of the night sky, each of these telescopes offers a very different path – and frankly, none is a complete astrophotography solution by itself in the traditional sense. Let’s break it down:

Celestron NexStar 8SE: This scope was primarily designed for visual observing, but many owners do dabble in astrophotography. Its strengths are in planetary imaging. Paired with a webcam-style planetary camera or even a smartphone, the 8SE’s long focal length can resolve planetary details nicely. The mount’s tracking (though alt-az) is fine for taking short videos of planets, which you can then stack to produce good images of Jupiter’s cloud belts or Saturn’s rings. Indeed, plenty of astrophotographers started by imaging planets with an 8SE – its optics are excellent and you only need ~1–2 minutes of video per planet (field rotation is negligible in that short span). For deep-sky astrophotography, the 8SE is less ideal out of the box. The alt-az mount means any single exposure beyond ~20–30 seconds will suffer field rotation blurring. Also, the mount’s precision and stability struggle with heavy camera attachments. Many 8SE owners who get serious about long-exposure astrophotography end up deforking the 8″ SCT tube and mounting it on a heavy equatorial mount or adding the optional wedge to the NexStar mount (which converts it to equatorial mode). With a wedge and careful polar alignment, people have managed decent long exposures with the 8SE, but it’s not a beginner-friendly setup for imaging. Additionally, at f/10 the SCT is slow (narrow field, long exposures needed). Using a focal reducer (f/6.3) or HyperStar (f/2) lens can speed it up for imaging, but those are additional investments. Space.com optimistically said the 8SE’s smooth tracking could make it “fantastic for long exposure astrophotography” space.com, and while it’s true the tracking motors are good, the limitations of field rotation and mount stability remain. In practice, the 8SE is best suited to EAA (Electronically-Assisted Astronomy) or casual imaging: you can attach a DSLR or astro-camera and stack many short (10–15s) exposures of say Orion Nebula or Andromeda Galaxy to get a decent image. It’s a bit like doing manually what the eVscope automates. But if one’s dream is detailed, high-resolution deep-sky images, a German equatorial mount with an APO refractor or dedicated astrograph would be a more common recommendation than the 8SE. In short: planetary imaging – yes, 8SE is a great tool; deep-sky imaging – possible, but requires extra effort and gear.

Apertura AD8: This telescope is marketed as a visual instrument, and indeed for imaging it has significant challenges. Being a manual Dobsonian, it has no tracking, so taking long exposures is impractical. The Earth’s rotation will smear stars in a matter of seconds at high magnification. Some enthusiasts use equatorial platforms (a tilting base that gives 5–10 minutes of tracking to a Dob), but that’s an accessory typically costing nearly as much as the scope itself. Without tracking, you’re mostly limited to very short snapshots – for example, holding a smartphone to the eyepiece to snap the Moon or planets (a common practice at star parties). Pleasing lunar photos and even basic shots of Jupiter’s moons can be done that way. But trying to image nebulae or galaxies with an untracked Dob is an exercise in frustration. The AD8’s strong point is visual use; to leverage its optics for imaging, one might take the AD8’s optical tube and put it on an equatorial mount (as some astrophotographers do with Newtonians). However, the steel tube AD8 is quite heavy (~20 lbs) and long, requiring a hefty mount to stabilize – again not really cost-effective versus buying a telescope designed for imaging. One TelescopicWatch critique noted you could “buy a pretty nice big Dobsonian and fill up your gas tank for trips to dark skies…for the price of [an eVscope 2]” – implying a big manual Dob plus dark sky can yield better visual views than a small smart scope. But that same big Dob (AD8) in dark skies still won’t create astrophotos without additional equipment. So, if astrophotography is a primary interest and you own an AD8, you would be looking at significant modifications (tracking platform, camera adapters, etc.) or more likely, a different rig entirely. Bottom line: The AD8 is not intended for astrophotography, aside from casual Moon shots or experimental planetary videos by manually keeping the planet in view (which is quite hard at high power). It’s the one out of these three that we’d clearly label “visual-only” for 99% of users.

Unistellar eVscope 2: Astrophotography is literally the eVscope’s raison d’être – though it’s a very particular style of AP. It automates image capture and stacking, producing a final image on your phone that you can save or share. For someone who doesn’t want to learn the intricacies of astrophotography (polar alignment, guiding, image processing, etc.), the eVscope 2 is a dream: you tap an object, wait a few minutes, and you have a presentable image of it. You can even see the image improve in real-time. In that sense, the eVscope is a fantastic tool for casual astrophotography and outreach. However, the images it produces have limitations. The resolution is modest (7.7 MP, and limited by a 114 mm aperture’s resolving power). The dynamic range is constrained by the short exposures used. Fine details or very dim stars may not show up as they would in a longer manually processed shot. Serious astrophotographers might find the eVscope images noisy or lacking compared to what they could get with a dedicated setup of similar cost. In fact, one astronomy reviewer argued that the eVscope 2’s deep-sky imaging “could be duplicated with a kit-bashed basic astrophotography setup for a small fraction of the price”, given some effort and know-how. That said, ease is a huge factor. Not everyone wants to haul a laptop, fiddle with cables and filter wheels, then spend hours post-processing. The eVscope lets you do astrophotography in a very laid-back, quick fashion – even from a city apartment balcony. For many, that trade-off is worth it. It’s telling that the eVscope 2 is often compared less to traditional telescopes and more to “astrophotography rigs.” For instance, Celestron’s upcoming smart scope (the Origin) is pitched as “you won’t need to buy one of each of the best cameras, best telescopes, star tracker, etc.” because it’s all integrated space.com. The eVscope similarly combines those components. Long exposure limits: The eVscope’s alt-az mount and in-built processing cap it at around 4-second sub-exposures, but it stacks dozens to simulate a longer exposure. You won’t be doing any single exposure hour-long photos, but you can accumulate, say, 10 minutes of total exposure through stacking and achieve a comparable result for many objects. The user can save the stacked image (a PNG or FITS file) via the app. There is no option to attach your own camera or change the sensor – it’s a closed system. So, astrophotography with eVscope is very much WYSIWYG (what you see is what you get). Notably, planetary imaging is a weakness of eVscope 2: its sensor is not optimized for high-frame-rate planetary capture, and the 4.5″ aperture and ~50x magnification limit means Jupiter or Saturn appear quite small on the screen. The new Unistellar models (Odyssey) introduced a “planetary mode” to address this, but with the eVscope 2, planets are more for casual observing than producing detailed images. If your focus is imaging planets, the 8SE with a proper camera would beat the eVscope handily. If your focus is imaging deep-sky objects with minimal effort, the eVscope is extremely appealing – albeit at a high cost. As one Live Science reviewer concluded, the eVscope 2 is “one of the best [telescopes] we’ve ever tested” for its all-in-one imaging power, but “with prices starting at $4,899.00, it really is only for experienced, and wealthy astronomers.”

In summary, for budding astrophotographers: the NexStar 8SE offers a gentle introduction via planetary imaging and limited deep-sky EAA, but you’ll soon bump against its mount’s limits. The Apertura AD8 is mainly a visual instrument – astrophotography with it would be an uphill battle without extra gear. The Unistellar eVscope 2 excels at convenient imaging of deep-sky objects and sharing those images instantly, but it’s not a traditional platform where you can grow skills like manual processing or swapping cameras. If one’s serious about astrophotography as a hobby (enjoying the technical process and maximizing image quality), they might outgrow the eVscope’s capabilities or find its results limited. On the other hand, if one’s goal is to enjoy pictures of the universe with minimal fuss, the eVscope 2 (and similar smart scopes) represent a revolutionary shortcut. And it’s worth noting: Celestron’s newly announced Origin smart telescope explicitly targets this niche, combining a 6-inch astrograph with a camera and “AI” processing to deliver images without the usual hassles space.com. The competition in 2025 clearly recognizes that many people want astrophotography results but without the steep learning curve.

Portability and Setup Complexity

These telescopes vary widely in size, weight, and how easy they are to transport and set up. Let’s compare:

Size & Weight: The Apertura AD8 is physically the largest and heaviest. Its optical tube is about 45 inches (114 cm) long and 9.25″ in diameter (with a solid metal tube), and the wooden base is bulky. The tube weighs ~20 lb (9 kg) and the base around 20 lb as well. It’s often said an 8″ Dob is the largest telescope an average adult can easily move in one piece. You can carry the AD8 in two trips (base and tube separately) without much issue, but it’s not something you’d hike with. It fits in most cars, though sometimes not in a small trunk – “the AD8’s tube is about 2″ longer than some other 8″ Dobs… may not fit in the trunk of smaller vehicles and must be laid across a back seat” telescopicwatch.com. Once at a site, setup is simply placing the base down and lifting the tube onto it (if you detached it). There are no screws or alignment needed – the tube’s side bearings drop into the base’s cradle. Collimation might be needed each time you transport it, which adds a few minutes to setup. Overall, going from packed to observing with the AD8 might take ~5–10 minutes, mostly for checking collimation and attaching finders/eyepieces. The NexStar 8SE is more compact when broken down. The 8″ SCT tube is only ~17″ long thanks to its folded light path, and it weighs about 12 lb (5.5 kg). The fork arm and electronics weigh another ~9 lb, and the tripod ~10 lb. So altogether, the 8SE kit is around 32 lb (14.5 kg) distributed in three pieces space.com space.com. Many users find this quite portable – the tube+fork can be carried while attached, and the tripod separately. It’s possible to carry the 8SE fully assembled if you’re careful (total 32 lb), but it’s a bit awkward; most prefer to remove the tube+mount (which detach via a dovetail clamp) for transport. Assembly involves spreading the tripod, mounting the fork arm onto it (one built-in bolt to secure), and sliding the OTA onto the dovetail bracket. It’s a tool-less process that takes maybe 5 minutes. The payoff for that assembly is a much more compact storage size than the Dob. The 8SE can even be taken on flights if packed well (the OTA fits in a carry-on case for example, though the tripod would go in checked luggage). Portability is one reason the 8SE has been a top seller – “one of the most compact deep sky telescopes…making it possible to carry around with relative ease” space.com. The Unistellar eVscope 2 is the lightest of the trio. The whole unit (tube + fork arm + built-in battery) is ~19 lb (9 kg), plus the tripod at ~2.5 kg. It’s about 26″ tall when assembled. It comes with a backpack in some bundles, making it extremely convenient for travel. This is a telescope you could take on a hike or carry to a remote spot easily. Setup is just unfolding the tripod, mounting the small fork (I believe it attaches via a bolt), and turning it on. In a couple of minutes it will align itself. It’s arguably the fastest and easiest setup: there’s no alignment procedure for the user, no collimation, and no extra accessories to plug in (since the camera, etc., are internal). From packed to observing could be <5 minutes. This simplicity is a huge boon for those who might be deterred by heavy or complex gear. As one reviewer noted, “Gone is the complex dance of star alignment… housed in a sleek, minimalist tube and mount the eVscope 2 does it all.”

Home Use vs Travel: If you mainly observe from your backyard, all three are manageable. The AD8 Dob just needs a corner of a room or garage to store (some have wheels or a hand cart to roll it out). The 8SE can live in a closet easily. The eVscope 2 could fit on a shelf or in its backpack. If you need to carry your scope down stairs or on public transport, the eVscope 2 wins hands down – it’s the only one truly comfortable to walk around with. The 8SE is second, being relatively compact and splitting into pieces. The AD8 is more of a car-to-field instrument; you wouldn’t want to lug it long distances by hand routinely. Apertura does not offer fancy carrying cases by default (though one can get a padded bag for the OTA). The eVscope, being marketed to urban dwellers, emphasizes portability – Unistellar even quotes the weight as just 8.8 lbs for the telescope (4 kg) which excludes the tripod. With tripod it’s ~14.3 kg total, but still very manageable.

Setup Complexity: The Apertura AD8 has an initial assembly (bolting the base together from panels) which might take an hour once, but after that, nightly setup is straightforward. Collimation is the trickiest part – learning to align the mirrors with a collimation cap or laser. Beginners might take 10+ minutes at first to collimate until they get the hang of it. Thereafter, one or two minutes is all it takes to tweak the mirrors before observing. The AD8’s included manual provides guidance, and there are many tutorials (HighPoint’s own videos, etc.). One TelescopicWatch tip: remove the mirror cell locking bolts to make collimation less confusing telescopicwatch.com. Beyond collimation, finding targets is the other challenge – star-hopping has a learning curve. But the actual operation of the scope is very simple (point, look, adjust). Many novices actually appreciate the low complexity once the scope is pointed: there are no coordinates or controllers to fiddle with at night. Contrast that with the NexStar 8SE, where setup involves leveling the tripod, inputting date/time (unless you have the newer WiFi module that does it automatically), and doing a 2-star or 3-star alignment. The alignment process for a GoTo can confuse some newcomers (e.g. making sure you centered the correct star). Celestron’s manual and SkyPortal app have made this easier over time (the app can do “SkyAlign” by picking any three bright points). Typically, a careful alignment on the 8SE takes ~5 minutes. After that, it’s smooth sailing – you select objects and the GoTo does the work. If alignment is done well, objects usually land in the eyepiece field. If done poorly, one might have to redo it. There’s a bit of a knack to it (using the up/right final motion, defocusing star to center easier, etc.) which experienced users know. This up-front complexity is often rewarded by a relaxing observing session afterward. So, the 8SE has a moderate setup complexity: more than the Dob (which you just plop down and observe), but far less than an astrophotography rig. An added complexity: power. You need to supply 12V to the 8SE – either fresh batteries or an external pack. Remembering to charge your PowerTank or carry extension cords is an extra step that purely manual scopes don’t have.

The eVscope 2 is by far the simplest to set up for actual use: turn on, open the app, and it aligns itself. There’s no need to know star names or use finders. It’s designed for people who might not even recognize Polaris – truly “push-button.” One user report humorously noted that Unistellar’s advertising disparages traditional scopes as too hard, implying with eVscope “no more choosing the right gear or mastering complicated techniques”. Indeed, if you can use a smartphone app, you can use eVscope. Focus is automatic or at least assisted (the eVscope 2 has an electronic focus motor you adjust via app, and it shows a live FFT for sharpness). The only technical things you might occasionally do are update firmware or calibrate the sensor (like taking a dark frame calibration, which the app can do). The app’s live view and sliders allow some control (e.g. increasing exposure time or gain), but one need not tinker – the defaults work. In terms of time from arriving on site to viewing an object, eVscope might be the fastest: a couple minutes for auto-align and you’re already looking at a live-stacked image. Compare that to setting up the 8SE (5 min align) or getting an object manually in the AD8 (could be instant for the Moon, or 10+ minutes if star-hopping to a faint galaxy). Where the eVscope loses simplicity is outside of operation – namely, you must manage battery charging, and you rely on a smartphone. If your phone dies or WiFi interference occurs, it can interrupt the session. Traditional scopes have no such concerns. But overall, the barrier to entry with eVscope 2 is extremely low; astronomy clubs report that people with zero telescope experience can get results with it on the first try, which is rarely true for a manual or even GoTo scope.

In terms of portability rankings: eVscope 2 (most portable) > NexStar 8SE > Apertura AD8. For setup complexity: eVscope 2 (easiest) > Apertura AD8 (easy hardware, but learning sky navigation and collimation) > NexStar 8SE (easy once you know how, but alignment steps and power add complexity). Each has some quirk: the AD8 might require a cooldown period for the mirror (hence the fan to speed it up) and collimation checks; the 8SE requires aligning and power; the eVscope requires a charged battery and a working smart device. But none of them require an advanced degree – they’re all user-level manageable. As one astronomy educator might put it: if you enjoy assembling Ikea furniture, the Dob will be fine; if you can program a DVR or use a DSLR, the GoTo alignment is no big deal; and if you’re comfortable with apps and WiFi, the eVscope is a breeze.

User Experience in Observing

“User experience” encompasses what it’s like to actually observe with these telescopes – the enjoyment, the interface, the comfort, and any frustrations. Each scope provides a distinct experience:

NexStar 8SE – The Classic GoTo Experience: Observing with the 8SE typically means looking through an eyepiece at real photons from space, while the mount obediently points wherever you ask. The thrill of dialing in exotic objects on the hand controller and having them appear in view is significant – especially for a beginner who might otherwise not find, say, a faint planetary nebula on their own. Once an object is centered, the tracking keeps it there, so you can relax and absorb the view. This is fantastic for public outreach or sharing with family: you can tell someone “come take a look at Saturn!” and not worry it’s drifted off. Using the 8SE’s hand controller is a bit reminiscent of using a 90s cell phone: you scroll menus, enter Messier or NGC numbers, etc. It’s functional but not flashy. There is a certain charm to it for techies, and it doesn’t distract much once you get used to where things are in the menu. Some users have moved to controlling the 8SE with their smartphone (Celestron’s SkyPortal app via WiFi), which gives a modern planetarium interface – that can improve the experience further for those who prefer tapping objects on a sky map. At the eyepiece, the 8SE can deliver stunning views – an 8-inch SCT has enough aperture to resolve globular clusters into stars, show the spiral structure of bright galaxies (under good conditions), and reveal subtle color in nebulae like Orion. One limitation is the narrow field: at most ~1° of sky (about two Moon-diameters) with a 2″ eyepiece or ~0.5° with the included 1.25″ 25mm. So big targets like the Andromeda Galaxy barely fit, and some star clusters can’t be fully framed. The optics themselves yield high contrast and sharpness on-axis, so planets and double stars are a joy. The long focal length makes achieving high magnification easy (just use a 10mm or 8mm eyepiece to get 200x+). However, the mount’s stability at those powers is so-so – focusing can jiggle the view, which is a common complaint. Many 8SE users learn a light touch or use an electric focuser to avoid the wiggles. As a GoTo SCT, the 8SE does require attention to power (battery) and sometimes dew. SCTs have a front corrector lens that is notorious for dewing up in humid climates. So part of the experience might involve using a dew shield or heater strip on moist nights. It’s an extra bit of hassle to note (Dobsonians can dew too, but less often on the primary; their eyepieces or finders dew more). When everything is working, the 8SE is “a fantastic telescope that would suit a beginner, intermediate or advanced skywatcher… simple enough for a beginner to get to grips with, but also please an advanced user” space.com. That quote underlines one great aspect of the 8SE’s user experience: it’s versatile. A newbie can rely on GoTo and see a lot their first night; an experienced observer might use the 8SE as a quick grab-and-go or as a planetary workhorse. The SCT optical tube is also upgradable – you can put it on a heavier mount later, or add accessories like binoviewers, better diagonals, filters, etc. The 8SE is like a gateway to serious observing (indeed “the 8SE was my gateway drug…just do it!” said one AstroBackyard reader). The main detractions in user experience: the alignment routine (some find it annoying every session), the need for external power if you don’t want to feed AA batteries, and the aforementioned focusing shakes. Also, because it’s all computerized, if something fails (motor stall, low battery) your session can be interrupted – whereas a manual scope has nothing to crash. But generally, the 8SE is well-regarded because it streamlines finding things yet still gives a traditional telescopic view. Many users report spending hours just slewing from one object to the next in a tour, marveling at what the 8″ optics deliver, which is an experience filled with discovery and excitement – exactly what a good telescope should provide.

Apertura AD8 – The Engaging Manual Experience: Observing with the AD8 Dobsonian is often described as immersive and intuitive. You push the scope and it moves where you point – as simple as that. There’s a sense of connection: you are literally guiding the telescope by hand across the starry sky. This tactile engagement can be deeply satisfying for those who enjoy learning the constellations and “star-hopping.” It feels like a skill – and it is; over time you become adept at quickly aiming the tube at a new target by recognizing sky patterns. Users often comment that finding a faint galaxy on your own is a thrill unmatched by simply punching it into a computer. The AD8 supports that experience by providing a right-angle correct-image finderscope (which makes navigating star charts easier) and a wide-field 2″ eyepiece (30mm SuperView) giving 40x magnification and about a 1.7° field – wide enough to capture big targets and star-hop effectively. The Dob mount’s motions are smooth, though some note the AD8’s altitude bearing design is a bit different (it uses a tension clutch and springs). It might take a little tuning to get the motion ideal (e.g., balancing the tension so the tube stays put when you let go, but isn’t too stiff to nudge). Once that’s sorted, tracking an object manually becomes second nature – one hand on the tube or a knob, gently pushing every so often to recentralize the object. At low-medium powers, an object can stay in view for a minute or more before needing adjustment. At high powers (for planets), you have to keep almost constant watch, nudging every few seconds. Some find this tedious, others don’t mind the challenge. An often-cited downside is that when sharing views, by the time a second person looks, the object might have drifted – so you have to realign it for each person. Despite these minor hassles, many beginners given an 8″ Dob describe the “wow” of seeing bright, clear views without any alignment fuss. “The Apertura AD8…offers everything you need to get started and views that won’t disappoint,” writes one reviewer, calling it highly recommended. There’s also comfort: the Dobsonian eyepiece position is usually at the top of the tube, about 4 feet off ground at zenith for an 8″ f/6 – a comfortable height when seated on a low stool. Observers appreciate being able to sit and move the scope, which is conducive to longer, relaxed observations. By contrast, with the 8SE on a tripod, you often stand or use an adjustable chair; the eyepiece moves with the scope angle (lower when pointed high, higher when low), so sometimes it’s awkward to reach. The AD8’s eyepiece also moves but roughly in an arc around 4’ high – generally ergonomic for most adults (shorter observers or kids might need a step stool at some angles). The lack of electronics means nothing to program, nothing that beeps or requires troubleshooting in the dark. On the flip side, the user experience can suffer in terms of finding new targets: it relies entirely on your knowledge or external aids. Some beginners can get discouraged if, say, they only saw the Moon and planets but failed to locate that galaxy they wanted to see. It requires patience and perhaps guidance from star charts or apps. The AD8 ameliorates initial needs by including two decent eyepieces and even a Moon filter. But likely, the user will eventually acquire more eyepieces to expand magnification options – which is part of the journey. Collimation, as mentioned, is part of the user routine; some enjoy tinkering, others view it as a chore. Thankfully, once learned, it’s quick – and seeing a perfectly collimated telescope snap into focus on a planet is rewarding. Maintenance aside (we’ll cover soon), the AD8 offers the most direct, “unmediated” stargazing experience of the three. It’s just you, the telescope, and the Universe – no screens, no cords. Many amateur astronomers started on a similar Dob and fondly recall the excitement of manually sweeping the Milky Way and stumbling upon a nebula or cluster. It cultivates observing skill. The user experience therefore skews towards those who are a bit hands-on and curious. For a purely casual user who wants instant gratification, the AD8 might feel like work at times. But for someone willing to engage, it can be the most personally satisfying in the long run. One Reddit user’s mini-review captured it: “It is a fine telescope…especially considering how inexpensive it was… but it just doesn’t cut it for the types of things I love to view (nebula, etc.)” – implying that without tracking or imaging assist, faint objects in light pollution can underwhelm. That’s an honest take: under suburban skies, faint galaxies in the AD8 will be faint fuzzies. Some people don’t enjoy that, whereas the eVscope would show a prettier picture. So experience can vary with environment: under truly dark skies, the AD8 provides a jaw-dropping visual experience with rich star fields and bright nebulae; under city skies, its views are significantly hindered by skyglow, which may leave a user craving the eVscope’s digital boost.

Unistellar eVscope 2 – The Digital “Enhanced” Experience: Using the eVscope 2 feels quite different from the other two. The most striking difference: you’re looking at a screen (or an electronic eyepiece), not directly at an optical view. For some, this is wonderful – you see colors and details in real-time that no normal eyepiece would show. For others, it’s a bit of a letdown in the “romance” of stargazing. The eVscope 2 tries to bridge that by providing an OLED eyepiece that you look into, giving a semblance of an eyepiece view, though you are still seeing a tiny screen inside. This does give a more intimate feel than just holding up a phone, and it’s high-quality (Nikon made, best in class according to Unistellar). Many users do appreciate having this eyepiece option – it makes it feel more like using a telescope and less like just watching an iPad. The visuals themselves: on bright objects like Orion Nebula or globular clusters, the eVscope’s live image can be stunning in a few minutes – you’ll see the greenish hue of the nebula, the resolved stars of the cluster. On extremely faint stuff, you might see something after stacking that you’d never see at all in an 8″ eyepiece from that location (like a supernova in a distant galaxy). It’s almost magical, especially to those who have only seen such images in books. The ease of obtaining those images cannot be overstated: no swapping eyepieces, no worrying about exit pupil or eye relief, no constant focusing adjustments (focus is mostly one-and-done per session). It’s a very comfortable, modern experience – one could sit in a lawn chair with a tablet on their lap while the telescope quietly does its thing a few feet away. In fact, the eVscope allows a sort of remote observing – you don’t even have to stay at the eyepiece. You could have friends across the yard join the telescope’s WiFi and see the view on their own devices simultaneously. This multi-user capability is excellent for outreach or group astronomy sessions. Compare that to the one-at-a-time queue at a Dob or SCT eyepiece. Another aspect is the “wow factor” for non-astronomers: show a newbie a faint grey smudge in an 8″ Dob, then show them a bright multi-color image of the same object on eVscope – the latter will likely get the bigger reaction. It’s more akin to the images people expect from NASA or Hubble (though not that quality, of course). For those who primarily want to explore and share views on social media or with friends, the eVscope is perfect – it even geotags and catalogs your observations. The user experience also involves dealing with tech: e.g., ensuring your phone stays connected to the scope’s WiFi (which means temporarily losing internet on that device), occasionally the app might glitch requiring a restart, etc. There’s also the reality that you are looking at a digital representation: the stars might appear pixelated when you zoom in, or there might be a slight lag as frames update. Traditional visual observing has a kind of immediacy and dynamic range (our eyes can simultaneously see faint and bright detail) that a screen view might not replicate fully. Some veteran observers find the eVscope experience a bit like “astronomy on rails” – guided and less spontaneous. You see what the device shows you, whereas with an analog scope you might catch an unexpected meteor, satellite, or subtle feature by eye. That said, the eVscope does allow some spontaneity: you can slew it manually via the app’s virtual joystick to scan around a region and it will plate-solve wherever you stop. It even has a “light pollution” indicator and will suggest interesting targets visible at that moment. There’s an element of gamification or tour-guide to the app. Unistellar continuously improves the software, adding things like planetary mode and multi-depth observing in newer models to broaden capabilities. But one expert on Cloudy Nights noted a critique: “the eVscope 2 has shown that 114mm diameter is not enough for a quality DSO image… the FOV is small compared to competitors… the price is nonsense these days” cloudynights.com. Essentially, while the user experience is high-tech and convenient, some feel the hardware (small mirror, small sensor) doesn’t justify the cost, especially now that other brands offer similar or better specs. It’s true that by 2025, competition in smart scopes (like Vaonis Stellina/Vespera, ZWO SeeStar) is rising, and even Celestron’s Origin is entering the fray. From a pure observing enjoyment perspective: the eVscope 2 can make each observing session feel like a mini astrophotography expedition – which either excites you or not. If you revel in capturing an image and saving it, you’ll be very pleased. If you love the serenity of just eyeballing photons in a quiet dark field, the eVscope might feel oddly disconnected (some have even joked it’s like playing a video game of astronomy rather than doing it – a harsh take, but it underscores the divide in preferences). One must also consider the citizen science angle: the sense of contributing to real research (like measuring an exoplanet’s transit light curve with your eVscope) can be hugely fulfilling, adding depth to the user experience beyond casual observing. Unistellar fosters that by sending alerts and even recognizing contributors in publications. That’s a unique experiential reward that the other scopes don’t offer out-of-the-box.

In summary, the 8SE offers a blend of convenience and classic viewing, the AD8 offers hands-on traditional stargazing with maximum personal engagement, and the eVscope 2 offers high-tech assisted viewing with immediate visual gratification and shareability. Each provides joy in different ways: The 8SE user might say, “I saw dozens of objects in one night, it was amazing and the views were sharp” space.com; the AD8 user might say, “I really learned my way around and the views felt ‘real’ and immersive”; the eVscope user might say, “I wowed my friends with a photo I took of a galaxy from my driveway!”. None is universally “better” – it depends on what experience you seek from astronomy.

Maintenance and Ongoing Care

Optical Maintenance: The Apertura AD8, being an open-tube Newtonian, will need the most frequent maintenance in terms of optics. Its primary mirror and secondary mirror are exposed to air; dust will accumulate on them over months and years. Typically, one might clean the primary mirror every 1-2 years (or as needed) by removing it from the cell and using distilled water/rinsing per standard procedure. It’s not hard but requires caution (so as not to scratch coatings). The secondary mirror rarely needs removal, but can be gently blown with air to remove dust occasionally. Collimation, as discussed, is a frequent task – many do it every session or every few sessions. The AD8 has a sturdy mirror cell, but things like bumpy car rides can knock alignment a bit off. The scope includes a laser collimator (though TelescopicWatch notes it may not be well calibrated itself). Many users upgrade to better collimation tools (Cheshire eyepiece, better laser) for peace of mind. The good news is the AD8’s solid tube tends to hold collimation reasonably well during a single session once set, and its mirrors are center-marked for ease. The Dobsonian mount of the AD8 is basically maintenance-free – maybe occasionally tightening screws or regluing Teflon if it wears after years. The base’s particle board should be kept dry to avoid swelling. The altitude bearings on AD8 are adjustable; some users tinker with adding Ebony Star formica or other mods to get ultra-smooth motion, but that’s optional tweaking rather than required maintenance. Another aspect: the reflective coatings on the AD8’s mirrors will gradually degrade over decade timescales. Perhaps after 10-15 years you might consider getting the mirror recoated if reflectivity has dropped noticeably. But that’s far down the line. In short, the AD8 needs periodic mirror alignment and cleaning, but is otherwise quite robust – no electronics to fail.

The NexStar 8SE SCT is relatively low-maintenance optically. Its tube is sealed (mostly – it has small vents but no open path for dust except when changing accessories). So the primary mirror stays clean for many years typically. The corrector plate (front lens) will get dew and dust – cleaning that glass carefully every so often (maybe once a year or when really needed) is the main task. Cleaning involves removing the corrector (if heavy cleaning) or doing it in place with lens solution; it’s delicate because of the special coatings. Many veterans say only clean when absolutely necessary, as a bit of dust won’t affect views. Collimation on the SCT is needed rarely – usually only if the scope gets a hard bump. It’s done by tweaking three screws on the secondary mirror. The 8SE can go a long time without collimation; one might check it a couple of times a year on a star test and adjust if needed. So in terms of optics, the 8SE is easier to keep aligned than the Dob (some owners never touch collimation for years). The closed tube also means less thermal issues – though SCTs do require cooldown to ambient temperature for best images (like any scope). The AD8 has a fan to expedite cooling; the 8SE doesn’t but because of its compact design it might take longer to cool its thick mirror if the temperature drop is large. Many mitigate that with insulating wraps or simply setting the scope out an hour early. The 8SE’s StarBright XLT coatings will last many years; one doesn’t generally recoat SCT mirrors as that’s complex – instead, if it ever needed it, you’d send it to Celestron or a specialist (but that’s uncommon unless decades old or stored improperly).

Electronics and Mechanics: The NexStar 8SE’s mount does have moving parts and electronics that require some care. The gearbox is mostly plastic/nylon gears – they are greased from factory and can run for years without issue. Heavy use might eventually require regreasing or tightening backlash (some owners do “tune-ups”). Keeping the mount clean (no dirt in gear meshes) and not overloading it (balance the OTA reasonably in its clamp) prolongs life. The hand controller firmware can be updated via PC, though if it’s working fine many don’t bother. Celestron does occasionally release firmware fixes or object database updates. The 8SE’s motors can drain batteries quickly if slewing a lot; running off a stable external battery or AC adapter is best – this prevents low-voltage hiccups that can cause alignment resets. In cold weather, the 8SE’s hand controller display can get sluggish (LCD in cold) – manageable by using a small handwarmer pouch near it or using a WiFi+phone instead. Physically, the SCT tube may develop image shift in the focuser over time (as noted by TelescopicWatch, the mirror moving focus “does cause some image shift”, but usually not severe). That’s inherent to SCT design and only addressed by upgrading to a Crayford focuser or similar if it bothers you. One maintenance tip: the 8SE’s collimation screws are metal; if you swap to thumbscrews (Bob’s Knobs), check that they remain tight – as Zane Landers noted, in his case the thumbscrews caused the scope to lose collimation more often, so he reverted to the factory screws telescopicwatch.com. Also, always cap the scope with a dust cap when not in use, and use a dew shield to prevent moisture dripping onto the corrector (dew can leave water spots if dried). The corrector plate can also get mold or fungus if stored long-term in a humid environment – silica gel packets in the case help if in a damp climate. Overall, maintenance for the 8SE is moderate: ensure power supply is healthy, occasionally clean optics, and mechanically treat it gently so as not to strip gears or misalign anything. Many 8SEs last for a decade or more of regular use without any major servicing, as long as they’re not abused.

Unistellar eVscope 2: Being an all-in-one electronic device, the eVscope 2 has maintenance needs more akin to a gadget than a traditional scope. Its primary mirror is sealed inside, so you won’t be touching that. If collimation goes out (say it’s dropped hard), you’d likely have to follow Unistellar’s support procedure which can involve adjusting screws while running a special collimation mode in the app – not something users commonly do unless necessary. The sensor is sealed behind an optical window; it might need a pixel calibration (the app can map out hot pixels via a dark frame). Battery care is a key maintenance aspect: the internal battery (likely Li-ion) should be charged periodically and not left empty for months. Unistellar suggests proper storage and notes the battery life span can be a few years. Cloudy Nights discussions mention Unistellar stating “battery life can be as short as 2 years and as long as 10” depending on usage and care. Eventually, the battery may hold less charge or fail – replacing it isn’t as simple as swapping AAs; you’d probably have to send the unit in or do an involved procedure to replace it (and a replacement battery source from Unistellar). That’s a longevity concern – in 10 years, will your eVscope still run 5 hours on a charge? Or will the company offer affordable battery replacements? Unistellar’s warranty and support cover battery for a period, but after that it’s an unknown cost. The software updates are another maintenance aspect: Unistellar releases app and firmware updates frequently (the changelog shows multiple updates in 2025 alone). Most add features or fix bugs, like the “Vivid Vision” update which improved contrast in images. Users should keep the app updated to enjoy new features, and update the scope’s firmware when prompted (which usually requires downloading data via phone – do that at home before heading to a remote site to avoid needing internet in the field). There’s a possibility of software issues – for instance, one must occasionally “recalibrate” or format the onboard storage if images get mis-saved, etc. These are the kind of minor troubleshooting steps more akin to dealing with a digital camera or computer. Unistellar seems proactive in support though, often reachable via their app/community for help. As for the hardware, the eVscope’s moving parts are the motors – these are low-torque slewing motors. They likely require no user maintenance beyond not physically forcing the scope when locked. There is an autofocus motor in the new Odyssey models, but the eVscope 2 lacks autofocus – you focus manually via app. That means fewer moving parts to break. The tripod and mount should be kept dry to avoid corrosion (just like any tripod). The external surfaces might need a wipe down occasionally. Importantly, don’t leave the eVscope 2 out in heavy dew or rain – electronics inside could be damaged. Traditional scopes are more forgiving if they get dewed (you just dry them out); an eVscope has circuits that you definitely want to keep dry. Also, extreme cold can shorten battery runtime; some eVscope users wrap the scope in insulating material in winter to keep temps up. There’s also an inherent limitation: you cannot easily upgrade components. If the camera sensor becomes outdated or if it fails after warranty, you rely on the manufacturer for repair or you’re stuck. In contrast, with a manual scope, if an eyepiece breaks you get a new one, or if the mount fails you can mount the tube elsewhere. The eVscope is a closed system – maintenance and repair are thus more centralized. That said, Unistellar has been around for a few years and presumably will service their products (often at a cost) if needed. Some early eVscope owners had to send units in for sensor replacement or other fixes. It’s like sending a DSLR to the company for servicing – it happens.

In terms of longevity: The AD8 Dobsonian could literally last a lifetime with mirror recoats every decade or two and maybe new accessories – it’s simple and nothing major will “die” on it aside from coatings. The NexStar 8SE’s optics similarly could last decades; the main question is whether the electronics will keep working (and if not, you can still use the 8″ OTA on a different mount – it’s standard). The eVscope’s longevity is tied to its electronics and battery – in 15 years, even if the optics are fine, will the app still be supported on whatever smartphones exist? Will Unistellar still provide server support or parts? These unknowns make some traditional astronomers hesitant, but for many users, a product lifecycle of 5-10 years is acceptable given tech progress – they might upgrade to a newer model by then anyway.

Cleaning the displays: One small maintenance: the eVscope’s electronic eyepiece (OLED) and the phone/tablet screens might need cleaning occasionally – nothing major, just wipe fingerprints. Meanwhile, the AD8 and 8SE have traditional eyepieces – those need cleaning occasionally too (eye lens can get smudged). Eyepiece and lens care (blowing dust, gentle lens cleaner for smudges) is standard for all.

Cost of ownership: The AD8 may encourage buying some extra accessories (more eyepieces, perhaps a Telrad finder, etc.), but those are optional. The 8SE might need a portable power supply purchase if you don’t have one, and many get a dew shield or a second eyepiece. The eVscope 2 doesn’t require extra eyepieces or filters (it can filter light pollution via software), but its ongoing cost could include replacing the battery or any subscription if Unistellar ever introduced one (currently, I don’t think they have subscription fees; the science campaign participation is free).

In summary, maintenance: the AD8 demands the most optical fiddling (collimation, cleaning), but minimal risk of functional failure. The 8SE demands keeping the mount happy (power, firmware) and occasional corrector cleaning/collimation – moderate fuss. The eVscope 2 demands battery management and software updates, with optics largely self-contained – low fuss day-to-day, but a reliance on manufacturer for any serious repair. Each telescope, if cared for properly, will serve its owner well, but the type of care differs – mechanical/optical vs electronic.

Latest News and Updates (2025)

Stargazing tech never stands still. As of August 2025, there have been some interesting developments and trends related to these models and their makers:

• Celestron NexStar 8SE: The 8SE continues to be sold and beloved in 2025, often appearing in “Best Telescope” lists. It’s frequently discounted during sales – for instance, one 2025 Prime Day deal had the 8SE at its cheapest price since January, showing it’s still in demand. Celestron hasn’t significantly updated the NexStar SE series in years, but they’ve expanded accessories around it (like the StarSense AutoAlign and SkyPortal WiFi) to keep it compatible with modern usage. The big news from Celestron is the introduction of a new smart telescope called the Celestron Origin. Unveiled at CES 2024, the Origin is a departure from the manual and SE lines – it’s a fully automated “intelligent observatory” with a built-in camera, essentially Celestron’s answer to Unistellar’s concept. The Origin has a 6-inch f/2.2 astrograph (RASA) design and can automatically align, focus, and even schedule imaging sessions overnight space.com space.com. It’s priced around $3,999, similar to the eVscope, and began shipping globally in Q2 2024. This indicates Celestron sees a strong market for smart telescopes. However, they clearly state it’s not for purists – “if you’re an out-and-out astronomy purist, Celestron’s newest AI-assisted arrival probably isn’t for you”. This echoes the split in the community. As for upcoming rumors: Celestron’s traditional lineup (like the NexStar SE and Evolution series) might get refreshes eventually, but no specific new 8″ SCT model has been confirmed as of 2025 beyond the Origin. The NexStar Evolution 8 (with built-in WiFi and battery) remains as a higher-end alternative to the 8SE, and in 2023 Celestron also launched some StarSense Explorer Dobsonians to cater to manual scope users who want smartphone guidance. So, Celestron is covering all bases. The enduring popularity of the 8SE is sometimes attributed to its “sweet spot” status. As AstroBackyard put it, “the Celestron NexStar 8SE computerized telescope is one of the best-selling telescope packages of all time” – a testament that even with new gadgets, people still flock to the 8SE for a reliable 8-inch experience.
• Apertura AD8 (and High Point Scientific): The Apertura line (High Point’s house brand) remains highly regarded, and the AD8 in particular often tops recommendations for best beginner or best value telescope. In 2024, High Point Scientific expanded the lineup with a new Apertura AD6 (a 6-inch Dobsonian), indicating success with their formula and a desire to cater to those who want a slightly smaller, cheaper option. The AD6 “just added” was touted as big news and positively reviewed as well. The AD8 itself hasn’t changed – it’s essentially the same GSO-manufactured deluxe Dobsonian it has been for years, with the nice Crayford focuser and accessory bundle. There was, however, the introduction of an Apertura Dobsonian Upgrade Kit (announced late 2022, updated 2023). This kit includes things like stronger secondary mirror springs (to hold collimation better), better primary springs and knobs, a light shroud, and setting circle kits. It’s an official recognition that some hobbyists like to tweak their Dobs for peak performance. With the kit, one can spend more time observing “and less time worrying about collimation or stray light”. This suggests High Point listens to user feedback – for example, some had noted the stock laser collimator isn’t great, or the finder could use an upgrade. Instead of changing the scope, they offer an optional kit. Availability: As of 2025, Apertura scopes are primarily sold through HighPoint in the US; availability globally might be under different brand names (GSO 8″ Deluxe, etc.). These scopes have sometimes faced stock shortages if manufacturing slows, but currently they’re readily available. In terms of popularity trends: the classic 8″ Dob remains one of the most recommended beginner telescopes on forums and guides, despite the rise of smart scopes. The value proposition is just so high (around $700–$800 for an AD8 vs thousands for a smart scope). Many astronomy educators still push Dobs as the way to get maximum aperture for the dollar and encourage learning the sky. Upcoming from Apertura? There aren’t “rumors” per se, since High Point isn’t the kind of company that teases future models. The lineup now covers 6, 8, 10, 12-inch Dobs, plus some APO refractors and imaging Newtonians under the Apertura name. It’s likely they’ll continue refining accessories but not necessarily drastically change the Dob formula – the telescope community expects what the AD8 offers, and any big changes (like adding GoTo motors) would raise the price and reduce the value advantage. So, expect the AD8 to stick around as a bestseller and “arguably the best value 8-inch Dobsonian you can ever find” for the foreseeable future.
• Unistellar eVscope 2: Since the eVscope 2’s release (late 2021/2022), Unistellar has been busy. In early 2023 they released the eQuinox 2, a second-generation version of their screenless model (similar specs to eVscope 2 but no eyepiece, at a lower price). By 2024, the big announcement was the new Unistellar Odyssey series. At CES 2024, Unistellar launched Odyssey ($2,499) and Odyssey Pro ($3,999) smart telescopes. These represent a new generation beyond eVscope. The Odyssey telescopes have a smaller aperture (85 mm vs 114 mm) but incorporate a new “Multi-Depth Technology” that allows effective observing of both deep-sky objects and planets. Essentially, they have a wider field, new sensor, and faster optics (f/3.8). They also introduced autofocus (finally) on these models. The Odyssey Pro reintroduces an eyepiece (with Nikon optics) like eVscope 2, while the base Odyssey is eyepiece-free like eQuinox. One might wonder why downsize to 85 mm – Unistellar seems to be aiming for a more affordable and compact unit, claiming their advanced processing compensates some for the smaller aperture. Indeed, Laurent Marfisi (Unistellar’s CEO) stated “they provide people who are not familiar with astronomy exactly the same meaningful experience as people who [are]” and emphasized user-friendliness. The response in the community was mixed: some note that 85 mm will have lower resolution; others like that the price of entry has come down (Odyssey at $2.5k is much cheaper than eVscope 2’s $4k+). Also noteworthy: Unistellar revealed they have 10,000+ smart telescopes sold worldwide by 2024, proving there is a substantial market. They also explicitly said the eVscope 2 and eQuinox 2 will continue to be sold alongside the Odyssey series. This likely means the eVscope 2 remains the flagship for maximum aperture and resolution in their lineup, at least for now, while Odyssey is “next-gen” with new features. Unistellar also partnered deeper with Nikon on these new models – which explains the emphasis on high-quality optics and perhaps better manufacturing. Another piece of news: a Odyssey Pro “Red” Limited Edition came out (just a color variant) in mid-2024, and they’ve done sales (the Space.com link mentions $675 off deals for Odyssey Pro). On the software side, Unistellar rolled out the 4.0 App in early 2024, unifying support for all models including Odyssey and adding features like improved image processing and the aforementioned “vivid vision” update (improved brightness/contrast in stacked images). They’ve made the platform fairly robust – eVscope users from 2020 received many firmware updates that improved things like mount accuracy and added objects (e.g. new comet discoveries are pushed to the catalog). One current event worth mentioning: eVscope users in 2024 participated in observing NASA’s Lucy mission asteroid targets and other campaigns, some of which got media attention. Unistellar is keen to publicize that “Citizen Astronomers have been recognized in scientific publications” for their contributions. This keeps the community engaged beyond just casual observing. In terms of popularity trends, the eVscope 2 (and its smart scope peers) are definitely gaining traction among hobbyists and newcomers with disposable income. Traditionalists may scoff, but plenty of folks are buying them – evidenced by new entrants like ZWO’s Seestar S50 (a $400 smart scope) which sold out quickly, targeting a different segment. The eVscope 2 specifically might see a price adjustment now that Odyssey Pro at the same $3999 has newer tech (though smaller aperture). Perhaps we’ll see eVscope 2 discounted more often (like Father’s Day $570 off deals were observed). As of now, the eVscope 2 remains one of the top “smart telescopes” but likely it’s nearing the end of its prime sales period as newer models take spotlight. Unistellar hasn’t announced an “eVscope 3”, and maybe Odyssey effectively is that under a new name.
• Competitive Landscape: We should mention briefly that Vaonis (a French competitor) has the Stellina and Vespera smart scopes, and recently a crowdfunded device called Hestia (which uses a smartphone as the sensor) – all signs that smart telescopes are a growing trend. And as noted, Celestron Origin and even Sky-Watcher (through a partner) hinted at smart scopes. For the consumer, this means more options at various price points, and potentially faster innovation. But for now, Celestron, Apertura, Unistellar represent three distinct philosophies: traditional GoTo, traditional manual, and fully digital.

In summary, Celestron’s big move is the AI-powered Origin (6″ imaging scope) in 2024, showing even the oldest name in telescopes is embracing “smart” tech. Apertura (High Point) is doubling down on value – adding smaller models and improvement kits to keep their Dobs the top choice for budget-conscious enthusiasts. Unistellar is iterating rapidly on its smart scope tech, with Odyssey being the latest evolution aiming to broaden appeal through easier planetary viewing and lower cost. And importantly for consumers, none of these developments make the three models we compared obsolete – rather, they highlight the choices: the 8SE remains a safe, all-around performer (now side by side with a new high-tech sibling, Origin), the AD8 remains a gold standard for visual bang-for-buck, and the eVscope 2 (plus its new Odyssey cousin) remains at the forefront of integrating astronomy with digital convenience.

Final Thoughts and Recommendations

Choosing between the NexStar 8SE, Apertura AD8, and Unistellar eVscope 2 ultimately comes down to your priorities, experience level, and budget. Each telescope excels for a certain type of user:

• Beginners: If you’re just starting out and want a hands-on learning experience (and the most aperture for your money), the Apertura AD8 Dobsonian is a top choice. It’s frequently recommended as a first serious scope because “the AD8 offers everything you need to get started and views that won’t disappoint”. You’ll learn the sky and get great views of planets and deep-sky objects, though be ready to spend time star-hopping and collimating occasionally. If instead you prefer some computer assistance right away, the NexStar 8SE is beginner-friendly after a short learning curve – Celestron’s tour mode can walk you through the night’s best sights. Just keep in mind an 8SE beginner should be prepared to handle the alignment process and maintenance like charging a power supply. For a wealthy beginner who wants zero hassle, the eVscope 2 can be alluring (it’s literally push-button easy, showing you beautiful images in minutes). However, most true beginners will balk at its price. Often, a good approach is to start with something like the AD8 to learn basics, then perhaps upgrade to digital enhancement later if desired.
• Casual Observers: If you view the night sky occasionally and value convenience and quick setup, the Unistellar eVscope 2 is almost tailor-made for you. It requires little knowledge or effort to use – you can wheel it out at a family gathering and have wow-factor images of galaxies to share in no time. The ability to share the view on multiple devices or save snapshots is great for casual use. The NexStar 8SE also serves casual observers well, especially if you want the experience of looking through an eyepiece but still have computer aid. It’s portable and relatively quick to set up, though you’ll need to refamiliarize yourself with alignment if you only use it sporadically. Casual users should consider whether they prefer a “traditional” view (8SE shows real-time views, which are dimmer but more natural) or a “enhanced” view (eVscope shows digital images that are bright and colorful). For many casual stargazers in light-polluted areas, the ability of the eVscope to punch through city skies is a huge plus – it’s “capable of revealing hidden stars…only visible in very dark sky locations” livescience.com. The Apertura AD8, while fantastic, might be less suited to very casual use because it’s larger to move and each session you’ll spend time hunting targets – which is fun if you’re into it, but might be frustrating if you just want a quick look now and then. Casual users often appreciate less setup and more instant gratification, tipping the scale toward the 8SE or eVscope.
• Citizen Scientists and Educators: If you’re keen to contribute to science or engage the public/crowds in observing, the Unistellar eVscope 2 stands out. Its network of users has participated in real research (e.g. confirming exoplanet transits, asteroid occultations) – owning one lets you join those campaigns with guidance from Unistellar. It’s essentially a small research station; for example, you can record the light curve of a variable star and export the data. Plus, for outreach events, an eVscope draws in people with its live images on a screen (it’s accessible even to those who struggle with an eyepiece). That said, an AD8 Dob or 8SE can also be used for citizen science in more traditional ways: you can estimate variable star magnitudes by eye, participate in meteor counts, or do planetary imaging for groups like ALPO. But these require more personal effort and add-ons (like cameras for the 8SE). If you’re a teacher or astronomy club leader, you might love the eVscope for its “instant results” that keep audiences engaged. On the flip side, showing students how to navigate the sky with a Dob or how a GoTo works with the 8SE can be very educational. Consider your setting: for urban citizen science (where light pollution is bad), the eVscope’s ability to digitally enhance is invaluable. In a rural setting with dark skies, a simple 8″ Dob might show enough to do projects without digital help. Overall, for organized citizen science programs, eVscope 2 (or its successor Odyssey) is an excellent tool – it was designed with that community in mind.
• Dedicated Visual Observers: If you are (or aim to be) an avid visual observer who spends long nights chasing faint fuzzies and planetary detail, the Apertura AD8 offers a purist experience and tremendous value. All of its budget goes into optics and sturdy mechanics, giving you the brightest views for the cost. Seasoned observers often recommend an 8″ Dob as something you can enjoy for a lifetime – it’s large enough to see hundreds of objects yet small enough to be manageable. The AD8 in particular comes with all the tweaks (fan, fine focuser) that an advanced user appreciates. You won’t outgrow it quickly. The NexStar 8SE also serves dedicated observers well, especially if you crave tracking. For example, if you love observing planets for extended periods or doing high-power double star splits, the 8SE tracking will let you observe without interruption, whereas with the Dob you’d be nudging constantly. The 8SE’s narrower field is a slight limitation for big deep-sky objects, but a dedicated observer might pair it with a small wide-field refractor eventually. In short, the AD8 = maximum immersion, 8SE = convenience and tracking for dedicated visual work. The eVscope 2 is less aimed at dedicated visual connoisseurs in the traditional sense, because it removes the direct-eye aspect. If your passion is visually detecting the faintest galaxy your aperture allows, the eVscope’s digital view might feel like “cheating” or simply not as thrilling. However, some dedicated observers who have moved to heavily light-polluted areas have adopted eVscopes to continue their hobby – it allows them to “see” things from the city that previously required travel to dark sites. It’s also worth noting, dedicated observers often end up with multiple scopes; an AD8 or 8SE could be a primary instrument, and something like an eVscope could complement as a specialized EAA tool.
• Aspiring Astrophotographers: If your ultimate goal is to produce high-quality astrophotography, you should be aware that neither the 8SE nor AD8 is an ideal one-stop astrophotography rig, and the eVscope’s imaging, while impressive, is limited to its built-in capabilities. For serious long-exposure photography, typically an equatorial mount and either a smaller refractor or camera lens setup is recommended. That said, consider how these three fit into an imaging journey: The 8SE can get you started on planetary imaging right away – it’s a proven platform for great shots of Jupiter, Saturn, the Moon, etc., with the addition of a <$300 planetary camera. If you want to try deep-sky imaging on the cheap, the 8SE’s alt-az mount can do short (sub-30s) exposures which you can stack on PC; it’s a learning experience in processing. Ultimately, many who catch the AP bug upgrade to a GEM (you could put the 8″ SCT on one, or get a new scope). But at least with the 8SE you have the option to repurpose the OTA for imaging (for example, there are many fine images taken with 8″ SCTs on better mounts). The AD8 Dobsonian is not recommended if astrophotography is a serious intent – unless you strictly care about visual or smartphone snapshots. You cannot turn it into an AP rig without essentially deconstructing it (buying rings, a mount, etc.). So if you suspect you want to dive into imaging, the AD8 might not be the best initial investment – perhaps a smaller ED refractor on an EQ mount would be better. The eVscope 2 is great if you want astrophotos without the learning curve, but not great if you specifically want to learn the art and science of astrophotography. It gives you results but not much control. If your aim is to produce wall-worthy high-res images or to tweak and process data, you might find the eVscope limiting. However, if you are more of a casual astrophotographer (you just want cool images as souvenirs of your observing sessions), the eVscope is perfect – it’s essentially doing the stacking and processing for you on the fly. As Space.com noted, the Celestron Origin and similar systems might actually be a cost-effective shortcut if you value your time and don’t want to buy separate cameras, trackers, etc. space.com. The eVscope falls in that same category. So, an aspiring astrophotographer who wants to learn and eventually do serious imaging: maybe lean towards the 8SE (knowing you’ll need to invest more later). One who wants pretty pictures now with minimal effort: eVscope 2 will satisfy, but you have to be content with its level of detail.

In the end, each of these telescopes can provide years of enjoyment under the stars, but they cater to different tastes. The good news is that none of them is a “wrong” choice – they’re all highly rated in their domains. As one reviewer nicely summed up: “the Celestron NexStar 8SE is a fantastic telescope” that can please a wide range of users space.com; the Apertura AD8 is often the best bang-for-buck telescope in its class; and the Unistellar eVscope 2, while polarizing, is undeniably a groundbreaking device that shows a glimpse of the future of amateur astronomy. Your decision should hinge on whether you favor hands-on tradition vs. high-tech innovation, and of course, your budget. An 8″ Dob will give you the most raw astronomy for the dollar, a GoTo SCT like the 8SE will give you a balance of convenience and performance, and a smart scope like eVscope will give you a modern, digitally-enhanced stargazing experience unlike anything else – at a premium price.

Recommendation Summary:

• Apertura AD8: Best for enthusiasts who want maximum visual performance per dollar, don’t mind manual operation, and are eager to learn the sky (excellent for beginners on a budget or seasoned observers who enjoy simplicity).
• Celestron NexStar 8SE: Best for users who want a blend of strong optics with computer assistance – great for those who value tracking and GoTo to find targets easily (ideal for intermediate beginners, technology-friendly newcomers, or as a versatile scope for any skill level).
• Unistellar eVscope 2: Best for those who prioritize ease of use, live imaging capability, and are willing to pay for it – perfect for outreach, urban astronomers, and anyone who wants to see deep-sky objects in color without dedicating hours to astrophotography or years to star-hopping (ideal for gadget lovers, educators, or citizen scientists with a healthy budget).
