Nikon D810A in 2025: Astrophotography Beast or Outshined by Modern Cameras?

Specialized Astro DSLR: The Nikon D810A is a 36.3 MP full-frame DSLR uniquely modified for astrophotography, capturing ~4× more hydrogen-alpha (Hα) light (656 nm) than regular cameras ^[1]. It was the first full-frame astro-specific DSLR when launched in 2015 ^[2].
Astro-Focused Features: It offers 15-minute exposures via a dedicated Long Exposure M mode (shutter speeds up to 900 sec) and a Virtual Live View Preview to aid focusing in the dark ^[3]. It also includes an “astro noise reduction” (dark frame subtraction) and red-lit UI elements to preserve night vision ^[4].
Not for Daylight: Nikon raised the base ISO to 200 (vs ISO 64 on a standard D810) and warns that the D810A is “not recommended for general photography” due to potential reddish casts in normal images ^[5] ^[6]. It’s purpose-built to excel at capturing nebulae – ordinary daytime scenes can appear tinted without additional filtration.
Top-Tier Image Quality: At release, Nikon touted the D810A’s sensor as delivering “the best image quality in the history of Nikon DSLRs” ^[7]. Reviewers confirmed its stellar low-noise performance, huge dynamic range, and sharp detail (no optical low-pass filter) made it exceptional for long exposures ^[8] ^[9].
Discontinued, Niche Availability: The D810A was a low-volume, specialty model – discontinued by early 2018 ^[10]. In 2025 it’s only found used or refurbished (often ~$1,500–$2,000 USD on the secondhand market ^[11]) since no brand-new stock remains. Its rarity keeps prices relatively high, reflecting continued demand among astro enthusiasts.
No Nikon Successor (Yet): Nikon has not released a D810A successor or any Z-mount mirrorless equivalent as of 2025. Astrophotographers either hold onto the D810A or turn to modifying newer Nikons (e.g. converting a Z6/Z7’s IR filter for Hα) ^[12]. A used Nikon Z6 plus third-party astro modification (~$800 total) is a popular modern alternative, albeit with some optical compromises at wide angles ^[13].
Facing Mirrorless Era: In the decade since the D810A, mirrorless models like Nikon’s Z7/Z8 and Canon’s EOS Ra emerged. The D810A’s 36 MP resolution and low thermal noise still hold up well, but newer sensors (BSI and stacked sensors) offer lower read noise and higher ISO limits ^[14]. The question in 2025 is whether the D810A’s astro advantages still shine against these modern “star shooters.”
Astro Trends 2025: Astrophotography is more popular than ever – from Milky Way landscape shots to deep-sky imaging. Pros today often recommend full-frame cameras with great high-ISO performance (e.g. Sony’s A7S III, Canon R6 Mark II, Nikon Z6 II) for nightscapes, or even cooled dedicated astro cameras for serious deep-sky work ^[15] ^[16]. The D810A remains a legendary tool in this niche, frequently discussed in forums even in 2025, but it’s now part of a broader toolkit amid advancing technology.

Introduction

In early 2015, Nikon surprised the astronomy and photography world by “aiming for the stars” with the D810A, a specialized version of its D810 DSLR designed exclusively for astrophotography ^[17]. This camera looked almost identical to a standard D810 on the outside, but its internals were tweaked for the night sky. Nikon equipped the D810A with a modified infrared-cut filter and firmware changes to make it exceptionally sensitive to the deep red glow of nebulae. For hobbyist and professional astrophotographers in 2015, it was a dream come true – a high-resolution, full-frame DSLR finally optimized for capturing the wonders of the cosmos.

Fast-forward to 2025: the Nikon D810A has long since been discontinued and Nikon’s camera lineup has largely transitioned to mirrorless models. Yet this unique DSLR’s legacy continues. Enthusiasts still debate its merits, compare it to newer cameras, and even seek out used D810A bodies for astrophotography. In this report, we’ll dive deep into the D810A’s technical specs and features, its status on the 2025 market, and how it stacks up against modern Nikon Z-series and rival cameras from Canon, Sony, and others. We’ll include expert opinions, recent developments, and what astrophotography trends mean for gear choices today. Whether you’re nostalgic about this one-of-a-kind Nikon or wondering how it compares to the latest mirrorless “star shooters,” read on for a comprehensive look at the D810A in 2025.

Core Specs and Astro Features of the Nikon D810A

The Nikon D810A is essentially a Nikon D810 at heart – 36.3 megapixel full-frame (FX) sensor, robust magnesium-alloy body, 1/8000s to 30s shutter (plus bulb) – with a few critical changes that make it a night-sky specialist. Most importantly, Nikon re-engineered the optical IR-cut filter on the sensor. This filter normally blocks certain red/infrared wavelengths to produce accurate colors in daylight photos. In the D810A, the filter was “optimized to allow transmission of the hydrogen-alpha spectral line,” yielding roughly four times greater sensitivity at 656 nm (the wavelength of the Hα emission from nebulae) ^[18] ^[19]. In practical terms, the D810A can record the vivid deep red light from cosmic hydrogen gas clouds far better than a normal camera. It reveals details in reddish emission nebulae (think the Horsehead Nebula or Orion Nebula’s loops) that would be almost invisible otherwise.

To complement the enhanced sensor, Nikon added several firmware features for astrophotography. One standout is the new “Long Exposure M” mode*, which allows selecting pre-set shutter speeds longer than 30 seconds – 60, 120, 240, 300, 600, and 900 sec (up to 15 minutes!) right on the dial ^[20] ^[21]. This meant shooters could do multi-minute exposures without needing an external intervalometer or timing in bulb mode – a big convenience for capturing faint galaxies or star trails. Additionally, in Live View the D810A offers a Virtual Exposure Preview for long exposures: essentially a boosted preview that simulates a 30-second exposure on the LCD, making it much easier to frame and focus on dark star fields before taking the real shot ^[22]. This feature, akin to Olympus’s “LiveTime” mode, lets you “see in the dark” for composition, a huge boon when pointing at invisible targets in the sky.

Nikon also recognized that long exposures generate noise and hot pixels, so they provided tools to combat that. The D810A has an “Astro Noise Reduction” option in Nikon’s Capture NX-D software to subtract thermal noise from RAW files ^[23] ^[24]. In-camera, users can enable long-exposure noise reduction (which takes a dark frame), but the camera’s low sensor noise often made that optional. In fact, experts noted the D810A’s thermal noise is so low and its “astro NR” so effective that “you won’t really need to shoot dark frames” in many cases ^[25] – a testament to Nikon’s sensor tuning. Another nice touch for night use: the viewfinder’s internal OLED info display can be dimmed, and the on-screen virtual horizon is shown in red – both meant to preserve your adapted night vision when working in darkness ^[26].

Under the hood, the D810A uses the same EXPEED 4 processor and 14-bit RAW output as the D810, ensuring that those long exposures capture maximum dynamic range and detail. The camera inherited the D810’s mirror and shutter vibration reduction tweaks and even offers Electronic First-Curtain Shutter (EFCS) in mirror-lock-up mode to eliminate micro-shakes ^[27] – critical when you might be doing a 5-minute exposure of a tiny star and want absolutely no blur. It’s clear Nikon threw everything into this model to make sure it produced the cleanest, sharpest astro images possible.

One trade-off of the D810A’s sensor modification is its behavior in normal photography. Because the IR/UV filter now lets much more red light through, daytime photos can have a pronounced red tint (e.g. blue skies and skin tones skew red). Nikon explicitly cautioned that while you can use the D810A for regular shooting, it’s not recommended for general photography because of that color cast ^[28] ^[29]. Also, to balance the increased red sensitivity and signal-to-noise for astro, the base ISO was raised to 200 (versus ISO 64 on a standard D810) ^[30]. The D810A’s native ISO range is 200–12,800 (expandable down to 100 and up to 51,200) ^[31] ^[32]. In practice, that base ISO 200 helps prevent overexposure when so much red light is flooding the sensor under long exposures, but it does sacrifice the ultra-low-ISO dynamic range that the normal D810 was famous for at ISO 64. Again, this camera was purpose-built for the night: in a dark sky, you’re typically shooting ISO 800–3200 anyway, not ISO 64. And at higher ISOs the D810A truly shines – its sensor’s low noise floor made it arguably “the best low-light/high ISO DSLR Nikon [had] ever made,” as one early tester opined ^[33]. (That claim came with a caveat: an initial comparison showed the D810A cleaner than the D810 at ISO 9000, though an NR setting may have influenced that result ^[34].)

In summary, the D810A’s core specs can be boiled down to: 36.3 MP FX sensor (7360×4912) with no optical low-pass filter, specialized IR filter passing Hα, ISO 200–12,800 normal range, 15 min exposures internally, and every feature needed for long-exposure stability (EFCS, intervalometer, etc.). It’s a hefty pro body (nearly 1 kg with battery), uses the F-mount for lenses, and has the same 3.2-inch LCD and viewfinder as the D810. It even shoots 1080p video (though most didn’t buy it for video). Nikon essentially took an already excellent landscape camera (the D810) and tuned it into a deep-sky imaging machine.

Market Availability in 2025: Can You Still Get a D810A?

If all this has you salivating for a D810A, you might ask: can I actually buy one today? The reality is that the D810A is a rare beast in 2025. Nikon produced it in relatively limited quantities (the astrophotography market is niche), and it quietly went out of production by late 2017/early 2018. In fact, by January 2018 the major retailers all listed the D810A as “discontinued” or out of stock ^[35]. Nikon never announced an official successor, so once the existing units sold out, that was it.

Today, your best bet is the used market. Enthusiast forums and resale sites occasionally have a D810A body for sale. As mentioned, typical used prices range from around $1,500 to $2,000 USD depending on condition ^[36]. This is notably higher than a normal D810 used price – reflecting the D810A’s scarcity and unique capabilities (for comparison, a regular D810 might go for $800–$1,000 used in 2025). If you do find a D810A on sale, it often commands a premium because there simply aren’t many alternatives if you want a factory-made H-alpha sensitive full-frame camera.

Nikon itself sometimes has refurbished units – for instance, Nikon USA’s online store listed a refurb D810A at ~$3,100 (which was essentially the original new price) ^[37] ^[38]. That indicates how in demand the camera can be: even years later, it can fetch close to its launch price. Buyers are willing to pay because modifying a normal camera isn’t cheap or as assured (more on that in a moment). It’s worth noting any D810A you find now will be out of warranty, and servicing such a specialized model could be tricky (Nikon Service centers would handle it like a D810, but if the sensor filter itself had issues, they might not have replacement parts on hand anymore).

Given the limited supply, some astro shooters have instead chosen to modify other cameras as a workaround. A popular path is to take a standard Nikon Z6 or Z7 (or a DSLR like the D850) and have a third-party service remove or replace the IR-cut filter for better Hα sensitivity. The economics can be compelling: as one astrophotographer noted, a used Z6 plus modification might total around $800, roughly half the cost of a second-hand D810A ^[39]. Moreover, the newer camera gives you modern perks (mirrorless viewfinder, newer sensor tech). However, DIY or third-party mods come with trade-offs: often the camera’s sensor cover glass isn’t optimized post-mod, which can introduce slight focus issues at infinity or star bloating in the corners with wide lenses (due to altered sensor stack thickness). The D810A, by contrast, was factory-designed to avoid such issues, maintaining sharp star images edge-to-edge ^[40]. Essentially, Nikon did the “mod” cleanly in-house for the D810A, whereas a modded Z6 is a bit of a hack by comparison.

Another factor is availability of new mirrorless glass vs classic F-mount. If you already own Nikon F lenses (or astro telescopes with F-mount adapters), a D810A slots right in. If you’re an all-mirrorless shooter, you’d need the FTZ adapter to use F lenses on Z bodies, etc. Some astrophotographers simply prefer the older DSLR chassis for certain tasks or for compatibility with existing accessories (like intervalometers, or because their tracking mounts and software are set up for DSLR control).

In 2025, because Nikon hasn’t offered a mirrorless D810A-equivalent, the resale value of the D810A has held strong. It’s a seller’s market – owners know they’ve got a unique piece of kit. There are reports of D810A units selling quickly whenever they pop up on classifieds, often to dedicated astro shooters who have been hunting for one. One user in mid-2025 wrote, “the price was right and I have a return window, so I’m going to give it a spin,” after finally finding a D810A, noting he was drawn by the promise of a hassle-free astro body compared to inconsistent third-party modified cameras ^[41].

If you do manage to acquire a D810A in 2025, you’ll likely be buying a camera that is around 8–10 years old. Be mindful of shutter count (astro time-lapses can rack up actuations) and sensor condition (check for hot pixels, though dark frame subtraction handles those). The battery tech (EN-EL15) is still common, and things like memory cards (CF and SD) are easy to find. In short, the D810A remains usable and supported in terms of media and accessories. Just don’t expect to find one new in box at B&H or Adorama – that ship sailed long ago ^[42].

Nikon D810A vs Nikon’s Current Lineup (DSLRs and Z-Series)

How does this venerable DSLR compare to Nikon’s newest cameras when it comes to astrophotography? Nikon’s lineup in 2025 is dominated by the Z-series mirrorless bodies, plus a few residual DSLRs. While none of these is a purpose-built “astro” camera, some are excellent low-light performers. Let’s break down the comparisons:

Resolution & Sensor Tech: The D810A’s 36.3MP sensor was high resolution for its time (2015). Nikon’s current full-frame sensors range from ~24MP (in models like the Z6 II) up to 45.7MP (Z7 II, Z8, Z9) and there are rumors of a 60MP sensor in a future Z7 III ^[43]. Higher pixel counts can capture finer detail in star fields if your optics and tracking are up to it. However, more pixels also mean smaller pixel size, which can reduce per-pixel sensitivity. Interestingly, the D810A’s pixel pitch (~4.8 µm) sits between the Z7’s 4.3 µm and the Z6’s 5.9 µm. So in terms of pixel size (a proxy for light gathering per pixel), a 24MP full-frame like the Z6 actually has larger pixels (better for signal-to-noise on a per-pixel basis), whereas a 45–60MP sensor has smaller pixels (potentially noisier per pixel, but you can bin or down-sample images to reduce noise).

In practice, Nikon’s newer sensors have advantages like BSI (back-side illumination) and more advanced ADCs that yield lower read noise. Astrophotographers measure things like read noise and dynamic range at high ISO, and indeed one user analyzing data noted the D810A’s read noise is higher than Nikon’s newer cameras (Z6, Z7, etc.) and its dynamic range only “marginally” better in the shadows ^[44]. This isn’t surprising – sensor tech marches on. The Z6’s 24MP BSI sensor, for example, has excellent low-light performance and very low read noise at high ISOs (some would say better than the D810/D810A). The Z8/Z9’s stacked 45MP sensor also performs superbly with low noise up through mid ISO ranges, though at very high ISO the simpler BSI sensor of the Z6 II might edge it out in noise.

However, none of those cameras natively pass H-alpha light. A stock Z7 II or Z8 will still block most 656 nm emission, so they won’t record nebulae reds without modification or external filters. So while a Z7 II might beat the D810A in baseline noise levels, the D810A will massively outperform it on something like the California Nebula (lots of Hα) because the Z7 II simply won’t register that deep red light well. This is the crux of why the D810A remains valued – its “sensitivity gap” in a specific part of the spectrum that normal cameras can’t match unless altered.

Low-Light and ISO: Nikon’s newer bodies also have much expanded ISO ranges. The D810A topped out at ISO 12,800 native (51k expanded). The Z9/Z8 go up to ISO 25,600 native (and way beyond expanded), the Z6 II up to 51,200 native. But maximum ISO numbers can be misleading; what matters is noise performance at useful settings like ISO 1600–6400 (common for night sky shoots). At those ISOs, cameras like the Nikon D850 (45MP DSLR from 2017) or the Z6 produce extremely clean images with perhaps a slight edge over the D810A in noise. The D850 in particular had a new BSI sensor that some astrophotographers modded for Hα and raved about its image quality (with base ISO 64 dynamic range and low thermal noise).

That said, the D810A was arguably Nikon’s king of low-light in its era. It even outperformed the flagship D4s (which had larger pixels but lower resolution) in some astro use-cases, thanks to that excellent Sony-made sensor and lack of star-eater noise reduction. In fact, NikonRumors reported a reader’s finding that at high ISO the D810A might be “the best low-light/high ISO DSLR Nikon has ever made,” beating the regular D810 in image cleanliness ^[45]. (Though an update admitted a noise reduction setting might have influenced the result ^[46].) Still, the takeaway is the D810A produces low-noise, high-fidelity results in dark conditions – and that holds true relative to many modern cameras except the very latest generation.

One point to compare is the dreaded “star eater” issue. In long-exposure astro, some cameras apply noise reduction that can mistakenly blur out small stars. Early Sony mirrorless cameras were infamous for this; Nikon DSLRs too had a “black point clipping” quirk in older models. The D810A, however, does not suffer from the star-eater problem – Nikon eliminated the aggressive NR blurring in this model ^[47]. (Jerry Lodriguss notes Nikon’s past “infamous ‘star eater’ algorithm” was gone in the D810A, with only minor black-level clipping remaining in certain cases ^[48].) Newer Nikon Z cameras don’t seem to have star-eater issues either, as Nikon generally allows true RAW output. Sony’s latest (A7R IV/V, A7S III) also have largely solved star-eating by reducing noise filtering at long exposures. But it’s something astro folks keep an eye on – and the D810A’s reputation is solid here.

Mirrorless Advantages: Shooting astro with a Nikon Z mirrorless body brings some new conveniences. For one, the EVF (electronic viewfinder) can amplify the scene – you can actually see stars and compose through the viewfinder, rather than having to use live view on the back LCD. Canon’s EOS Ra exploited this with a 30× magnification mode to fine-tune focus on stars ^[49] ^[50]. Nikon’s Z-series offers up to ~15× magnification in live view, and the EVFs are high resolution, which definitely helps in obtaining critical focus on a bright star. Focus peaking can also be used (though for very dim stars it’s less useful).

Another plus: no mirror slap. On a DSLR like D810A, one typically uses mirror lock-up or live view to avoid mirror vibration blur at the start of an exposure. The D810A’s EFCS helps here too. But mirrorless cameras have no mirror and often offer fully electronic shutter if needed – so vibration is even less a concern. For wide-field nightscape shots (Milky Way over a landscape), this is minor, but for telescopic shots at high focal length, removing mirror movement is nice.

Mirrorless bodies also tend to be a bit lighter and smaller. If you’re piggybacking a camera on a telescope or star tracker, less weight = less strain on the mount.

Battery and Ergonomics: One downside of mirrorless for long exposures is battery draw – an EVF and sensor-on live view will drain batteries faster than an optical viewfinder DSLR. The D810A can operate with its LCD off (OVF for framing, then shoot), sipping power. For multi-hour timelapses, you might get more frames out of a DSLR per battery. However, solutions exist (battery grips, or AC power adapters for both DSLR and mirrorless).

The D810A, being an older design, lacks things like built-in Wi-Fi or a tilting screen. Nikon originally suggested using accessories (UT-1/WT-5A) for wireless tethering ^[51]. In contrast, newer Nikons (Z6 II, etc.) have Wi-Fi/Bluetooth, and models like the Nikon D780 (a 2020 DSLR) even have a tilting touch screen and live view experience similar to mirrorless, making them more hybrid in use. A tilting screen is actually fantastic for astrophotography (no more craning your neck at the camera pointed to zenith!). The D810A’s fixed rear LCD is a pain point for some astro shooters in the field. One of the cons noted by Lodriguss in his review: “LCD screen not articulated” ^[52]. By 2025, most new cameras have some tilt or vari-angle capability, giving them an ergonomic edge for skyward compositions.

Upcoming Nikon models: As of 2025, rumors suggest Nikon will release a Z6 III and Z7 III with incremental improvements (possibly the Z7 III getting a 60MP sensor) ^[53]. There’s also the flagship class – eventually a Z9 II down the line. None of the rumor mill hints at an “astro edition” of any Nikon mirrorless. Nikon seems focused on broad-market models. That means if you want a Nikon for astro today, you either use a regular model or find a D810A. Nikon also discontinued its remaining high-end DSLR, the D6, and there’s no indication of a “D850A” or similar ever being made. So, the D810A is likely to remain a one-off in Nikon’s history for now.

Internal Competition – D850 and D780: A quick note on Nikon’s last DSLRs: the Nikon D850 (2017) is a 45MP powerhouse that many call the “DSLR that does it all.” While not astro-specific, its sensor is phenomenal ( DxO rated it one of the best in dynamic range). Some astrophotographers who didn’t get a D810A opted to modify a D850 for H-alpha. A modded D850 can arguably outdo a D810A in resolution and maybe match its noise performance (the D850 has even lower read noise at low ISOs and similar at high ISOs). The D850 also has features like a tilting screen, illuminated buttons (handy at night), and better Live View focus. So within Nikon DSLRs, a case can be made that a modified D850 is the “real” successor to the D810A, albeit unofficial. Of course, that requires third-party conversion.

The Nikon D780 (2020) is another interesting DSLR – effectively a hybrid of a D750 body with the sensor and live view system of a Z6. It’s 24MP and excellent in low light. Again, not astro-specific, but if someone wanted a general camera that can do astro well (with a mod possibly), the D780 is a candidate. It even offers on-sensor phase-detect AF in live view and 4K video, unlike the older D810A.

Bottom line for Nikon vs Nikon: If your goal is pure astrophotography of emission nebulae and deep sky, a D810A still outperforms any stock Nikon simply by virtue of its Hα sensitivity. No amount of new sensor tech will help a stock camera pick up wavelengths its filter blocks. But for continuum subjects (like galaxies, reflection nebulae, Milky Way dust clouds) where Hα isn’t a factor, a newer Nikon like a Z8 or D850 (unmodified) will deliver cleaner files and higher resolution. And for nightscape photography (stars + landscape), the high ISO ability of cameras like the Z6 II – with clean output at ISO 12800+ – makes them very competitive. Many astro-landscape shooters have moved to mirrorless Z or Z7/8 for their modern conveniences, accepting that they lose some red nebulosity unless they use external filters or do a full-spectrum conversion.

It’s also notable that Nikon’s Z-mount has opened access to some incredible fast lenses (e.g. the Nikon Z 20mm f/1.8 S, or third-party ultra-fast lenses) which can benefit night photographers. F-mount also had gems (Sigma 14mm f/1.8, etc.), which the D810A can use. With adapters, a Z can use any F lens too, so lens selection is broad either way.

In sum, within Nikon’s realm the D810A remains a unique tool – the only one that natively does what it does. New Nikons boast general improvements but require modification to compete on the niche the D810A was born for. As one forum poster in 2025 mused, “any compelling reason to buy a D810A in 2025 over modifying a Z6 or Z7?” ^[54]. The answers boiled down to: yes, if you want a turn-key, optimized astro camera with no fuss (and you don’t mind the older DSLR platform). The D810A gives that out of the box. Otherwise, a modded newer body could be more economical and offer multi-purpose use. It really depends on the user’s priorities.

Rival Astrophotography Cameras: Canon, Sony, and Others

While Nikon users had the D810A, other major brands also dipped their toes (or in Canon’s case, took multiple plunges) into the astrophotography camera market. Let’s compare the D810A to its rivals and contemporaries, as well as consider cameras famed for low-light even if not astro-specialized.

Canon’s Astrophotography Line (20Da, 60Da, EOS Ra)

Canon was actually ahead of Nikon in offering factory astro cameras. All the way back in 2005, Canon released the EOS 20Da, an 8.2 MP APS-C DSLR with an H-alpha pass filter (based on the EOS 20D). It was groundbreaking at the time for astrophotographers. In 2012 Canon followed up with the EOS 60Da (18 MP APS-C) ^[55]. By the mid-2010s, many assumed Canon or Nikon might eventually do a full-frame astro camera – Nikon did with the D810A in 2015, and a few years later Canon answered with the EOS Ra.

Canon EOS Ra (2019): This is a mirrorless astro camera based on Canon’s EOS R full-frame system. It uses a 30.3 MP sensor (the same as in the EOS R) but with a modified IR filter. Canon stated the EOS Ra can capture “as much as 4×” the amount of Hα light compared to the standard EOS R ^[56] – very similar to Nikon’s 4× claim for the D810A. Like the Nikon, the Ra is not meant for normal photography (it’ll give red-tinted results unless corrected). One cool feature of the EOS Ra is its focusing aids: Canon added a 30× magnification option in live view/EVF, vs 10× on the normal model ^[57]. This was a direct nod to astrophotographers needing to fine-focus on stars – and is a benefit of mirrorless EVFs. The Ra otherwise has the same specs as an EOS R: 30MP, up to ISO 40,000, etc., and it can use the growing RF lens lineup (or EF lenses via adapter).

In terms of performance, the EOS Ra’s sensor is a generation newer than the D810A’s and being mirrorless, it has all the advantages of an EVF. Its pixel size (~5.36 µm) is slightly larger than D810A’s (4.8 µm), which helps a tad in noise. But broadly, these two are comparable in astro capability; each can record Hα nebulae that normal cameras would miss. The Ra, benefitting from Canon’s Dual Pixel CMOS AF, can even autofocus on stars (to some extent) and certainly on daytime subjects if someone tries to use it normally.

Canon priced the EOS Ra at around $2,499 at launch (late 2019) ^[58], notably lower cost than the D810A was initially. It was a modest success but still a niche item. By late 2021, Canon discontinued the EOS Ra (and even the original EOS R) as they shifted to newer R5/R6 bodies ^[59]. It means as of 2025, if you want an EOS Ra you also have to find it used. They do pop up occasionally for ~$1500–1800. So Nikon and Canon’s astro models both had limited lifespans and are now obtained second-hand.

Will Canon make another? Possibly – CanonRumors speculated that an EOS R5a (astro variant of the R5) could come in a few years ^[60]. Some in the community argue a “R6a” (20MP, lower noise) would make more sense than a high-res R5a ^[61], because too-high resolution can be overkill for astro (and the R6’s big pixels would give better SNR). As of 2025, though, Canon hasn’t announced any new astro model. The Ra remains their latest and only full-frame one to date.

How does the D810A compare to the Ra? If we pit them head to head: The Ra has newer sensor tech, mirrorless conveniences, and a slightly lower price (used). The D810A has ~6 MP more resolution and a proven track record of extremely low thermal noise. Canon’s 30MP sensor is excellent too (it’s the same chip as in the EOS 5D Mark IV, which astrophotographers respect for low noise). The Ra likely has a slight edge in high ISO noise and certainly in user experience, thanks to EVF and that 30× zoom. Nikon’s D810A might still win on dynamic range at base ISO (Nikon sensors of that era typically had better DR than Canon). But for astro, high ISO dynamic range is more relevant, and both are fine there.

One could say the EOS Ra was Canon finally catching up to Nikon’s D810A, and then surpassing it with mirrorless tech. It arrived 4 years later, so that makes sense. For someone in 2025 choosing between them, it might come down to system loyalty or availability – Canon shooters would grab the Ra, Nikon shooters the D810A. Both cameras keep the Astro-DSLR/ML concept alive even as most people just mod their normal cameras or use dedicated astro CCDs.

Sony: Low-Light Kings (Though No Official “A” Models)

Sony hasn’t released a dedicated astrophotography version of their cameras (no “Sony A7a” or such). However, Sony is a big player in astrophotography simply because of their sensor technology and specific models that excel in low-light. The most famous is the Sony α7S series.

The original Sony A7S (2014) stunned photographers with its 12-megapixel full-frame sensor that could shoot clean video at ISO 409,600 and essentially see in near darkness. For astrophotographers, the A7S (and later A7S II, A7S III) became legendary for Milky Way and night sky imaging – especially for time-lapse and video. With such large pixels (~8.4 µm!), the A7S could capture stars with minimal noise where other cameras struggled. One analysis by Lonely Speck (Ian Norman) found that the A7S has “two full stops more light-collecting potential” than a 36MP camera like the Nikon D810 at extremely low light levels, for the same noise level ^[62]. In other words, the A7S could hold image quality at ISO 51200 that matched what a higher-res camera might achieve at ISO 12800 ^[63] ^[64]. This was a game changer for certain astro use cases (e.g. real-time video of the Milky Way, or very short exposure stills).

Of course, the A7S isn’t H-alpha enhanced – it still has a normal filter, so nebulae would be subdued. But for general night sky (stars, Milky Way core, auroras), it excels. The low resolution is actually not a huge drawback for many, since noise is the limiting factor more than resolution in dark conditions.

Sony’s other models, like the A7 III (24 MP) and A7R IV (61 MP), are also popular for astro. The A7 III offered a great balance of resolution and low noise, and many astro-landscape shooters use it or the newer A7 IV (33 MP). The A7R V with 61 MP can produce incredibly detailed astro images (especially of star fields or wide vistas), though you have to shoot and stack many frames to overcome noise at the pixel level – a technique many use now given the high resolution.

Sony did face the “star eater” saga: older Alphas (A7R II, A7S II circa 2015–2016) had aggressive noise reduction in bulb exposures that would literally remove faint stars. This caused an outcry in the astro community. By the A7 III and later, Sony largely fixed this (by disabling that filtering in RAW, or reducing its effect). Nikon ironically had a similar issue long ago (D7000 era) but not to the same degree, and by D810A it was fully resolved ^[65].

While Sony doesn’t offer a factory astro model, they benefited indirectly from third parties: companies like Kolari Vision or LifePixel will modify Sony cameras by removing the IR cut filter (making them “full spectrum” or Hα sensitive). A number of astrophotographers have gotten their Sony A7 variants modified to create their own astro cameras. For instance, a modified Sony A7S can be a beast: huge pixels + Hα sensitivity + low read noise – it’s about the best you can do for capturing faint nebulae without cooling. One user posted an impressive Orion Nebula shot with a modified A7S on a telescope ^[66].

In 2025, Sony’s A7S III (2020) remains a top pick for those who value clean high ISO, especially for video or real-time viewing of the night sky. But for still astrophotography, many Sony shooters gravitate to the A7R V for its resolution or the A7 IV for a balance. It’s noteworthy that some of the best astro images nowadays are composites or stacks where noise is averaged out – meaning the advantage of the A7S (no stacking needed) is somewhat diminished if you’re willing to stack dozens of exposures from a higher-res camera to get both low noise and high detail.

Overall, Sony’s approach has been to make their regular cameras as good as possible in low light, rather than selling a separate astro model. This has worked well – Sony sensors (including those in Nikon bodies like the D810A and Z series) are the gold standard for low noise. But if you specifically need to capture that hydrogen-alpha emission, you’ll have to modify a Sony or use external filters (some use clip-in filters like the STC Astro-Multispectra to boost nebula contrast, but it’s not as effective as a full mod).

Other Notable Competitors and Technologies

Outside the Canikon/Sony sphere, a few other interesting options exist:

Pentax (Ricoh) and the Astrotracer: Pentax DSLRs (like the K-1 Mark II and K-3 series) have a unique Astrotracer function. These cameras feature in-body image stabilization (IBIS) that can move the sensor. With GPS data, the camera can shift the sensor during a long exposure to follow the stars’ apparent motion, effectively acting as a mini star tracker! For example, the Pentax K-1 II can do exposures of up to a few minutes with stars staying pin-point, by using its IBIS to counteract Earth’s rotation ^[67]. Originally you needed an add-on GPS unit (O-GPS1) for older models, but newer Pentax bodies have GPS built-in ^[68]. In 2022, Pentax even released firmware updates adding Astrotracer Type 2 and 3, one of which works without needing the GPS unit, using just the camera’s orientation sensors (for shorter durations) ^[69].

While Pentax’s Astrotracer doesn’t increase Hα sensitivity (the IR filter remains stock), it allows any Pentax DSLR to take longer unguided exposures before stars streak. This is fantastic for wide-field astro with a tripod – you can potentially shoot a 60-second exposure at 15mm with no trails, where other cameras would trail after ~15 seconds. It effectively boosts SNR by letting you use lower ISO or longer shutter. That said, Pentax’s sensors (often Sony-made as well) are similar to peers in noise performance. The K-1 II’s 36MP sensor, for instance, is like a cousin of the D810’s. And indeed astrophotographers have used Pentax cameras with success, praising the convenience of Astrotracer in the field.

Olympus / OM System OM-D E-M1 Mark III Astro (2024): Surprisingly, in 2024 the company formerly known as Olympus (now OM Digital Solutions) launched a dedicated astro version of a Micro Four Thirds camera. The OM System E-M1 Mark III ASTRO is a special edition of their 20MP MFT flagship, with a modified sensor filter for Hα capture ^[70] ^[71]. According to the press release, it achieves ~100% transmittance of Hα by optimizing the IR-cut filter ^[72]. It’s essentially a D810A-like concept but in a smaller sensor format. They also bundle it with a body-mounted filter set (likely light pollution filters, etc.) ^[73].

The E-M1 III Astro was initially only announced in Japan, slated for release July 2024 at around ¥327,800 (~$2,000) ^[74]. It’s marketed to cover “from starry sky photography to full-scale astrophotography such as constellations and nebulae” using Olympus’s computational features ^[75]. Notably, Olympus cameras have nifty tricks like Live Composite (for stacking light frames in-camera) and Handheld High-Res Shot (which might be used for stacking multiple short exposures for noise reduction). The Astro model presumably capitalizes on those for astro use.

While a Micro 4/3 sensor can’t match full-frame in low-light noise (due to smaller size), the existence of the E-M1 III Astro shows manufacturers still see a demand for astro-specialized cameras. Its smaller format might appeal to those who want a more portable rig. For example, an E-M1 III Astro with a Zuiko 7-14mm f/2.8 could be a compact Milky Way machine. It also could be mounted on telescopes with adapters, albeit with a 2× crop factor which some deep-sky imagers might find less ideal than full-frame.

By 2025, it’s unclear if OM System will offer that Astro model outside Japan or continue with an OM-1 Astro perhaps. But it’s an interesting competitor in the sense that Nikon and Canon did full-frame astro, and OM System did MFT astro.

Dedicated Cooled Astro Cameras: It’s worth mentioning that beyond “cameras” in the traditional sense, many astrophotographers – especially those focused on deep-sky imaging – use dedicated astronomy cameras from the likes of ZWO, QHY, Atik and others. These are essentially sensor packages (often using the same Sony sensors in our DSLRs) but in a body with thermoelectric cooling, no IR filter (or optional), and usually meant to be tethered to a computer. For instance, ZWO’s ASI6200 uses a 61MP full-frame sensor (same as Sony A7R IV) with cooling, and ASI2400 uses a 24MP full-frame. There are also popular APS-C astro cams (like ASI2600, 26MP, which one forum user in 2025 mentioned owning alongside his DSLRs ^[76]). These cameras have become very popular for those who do telescope imaging – they eliminate thermal noise via cooling and often have higher QE (quantum efficiency) since no Bayer CFA or specialized mono sensors for narrowband imaging.

Now, these aren’t directly comparable to a Nikon D810A, since they aren’t standalone (you need a laptop or a dedicated controller like an ASIAir) and they can’t be used for normal photography. But they absolutely impact the landscape: If someone’s goal is purely photographing nebulae and galaxies from a fixed observatory, they’d likely choose a cooled astro camera over a D810A today, because it’s more efficient and sensitive (and software support for capture/stacking is robust). As one astro imager bluntly said, “unless you plan to do some terrestrial shooting with such a camera, none of these [DSLR/MILC astro] cameras are remotely practical, as they are quite overpriced compared to a dedicated astro camera” ^[77]. This was in the context of discussing the D810A/Ra-type offerings. They argued a cooled camera gives better results for the price if you’re solely doing astrophotography. Another replied that for pure astro, indeed a modded or dedicated astro cam is better, “one is better off with a modded camera, or a dedicated cooled camera” ^[78].

However – and this is crucial – astro DSLRs still have a role: They are much more versatile and user-friendly for certain scenarios, like landscape astro or when you want to shoot without lugging a computer. One photographer in that same discussion countered that while he owns a cooled astro camera for deep-sky, he found using it with wide-angle lenses for landscape astro was “a massive hassle… not conducive to that kind of shooting.” He emphasized that “there is still a place for a traditional style camera in astrophotography”, especially for the popular realm of landscape Milky Way shots or when combining terrestrial scenery with the night sky ^[79]. In those cases, a DSLR or mirrorless that you can just mount on a tripod (or a simple star tracker) and shoot is far more convenient. You don’t need a laptop, you can frame and focus easily, and you can also use it for normal daytime photos on the same trip if needed. He guessed that “landscape astro… is still far more popular than deep-sky imaging” in terms of number of practitioners, so cameras like the D810A (or a hypothetical future “A” model) cater to that large group who want a foot in both worlds ^[80]. Another forum member quipped, “And [with a DSLR] no computer required in the field” ^[81] – which is a serious advantage if you’re hiking to a dark sky location.

To summarize the rivals: Canon’s EOS Ra was the direct competitor to the D810A, bringing mirrorless tech to the table. Sony’s cameras aren’t astro-specific, but models like the A7S III are monsters in low light and widely loved by astro shooters (though requiring modification for nebulae). Pentax offers an innovative approach with Astrotracer for those wanting longer exposures without a mount. OM System even introduced a micro four-thirds astro camera, indicating interest in specialized tools persists. And beyond the traditional camera makers, dedicated astro cameras have advanced to the point that many serious imagers forego DSLR-type cameras entirely for deep-sky projects.

The Nikon D810A sits in this mix as a kind of cult classic. It wasn’t produced in huge numbers, but those who have it often swear by it. Even in 2025, you’ll find experienced folks on Cloudy Nights or similar forums still using their D810A to capture stunning nebulae images, or newcomers asking if they should get one versus adapting a new mirrorless.

The image above demonstrates what the D810A can do that stock cameras would struggle with – notice the rich crimson filaments of ionized hydrogen gas in the Veil Nebula. A regular camera would record much fainter pinkish wisps here, but the D810A’s sensor, being designed for this task, brings out the vivid Hα structures. This is the kind of result that still has astrophotographers checking eBay for a D810A body in 2025!

Expert Opinions and 2025 Perspectives

When it debuted, the D810A garnered praise from both camera reviewers and the astro community. Nikon’s own marketing quoted Nikon Inc.’s Director of Marketing, Masahiro Horie, as saying “The Nikon D810A is engineered exclusively to meet the unique demands of professional and hobbyist astrophotographers”, designed so users can “discover the fantastic cosmic features that are hidden among the stars.” ^[82] ^[83] This wasn’t just fluff – Nikon truly addressed astro needs.

Seasoned astrophotographer Jerry Lodriguss reviewed the D810A and validated Nikon’s claims. He noted that Nikon said the D810A had “the best image quality in the history of Nikon DSLRs” and added, “I found this to be true.” ^[84] He lauded its low noise and high sensitivity, observing that “deep-sky astrophotographers will love the camera’s low noise, hydrogen-alpha sensitivity, and excellent dynamic range.” ^[85] ^[86] In his conclusion, Lodriguss called the D810A a “well-executed, high-end” astro DSLR and listed its pros as high resolution, very low noise, strong Hα response, built-in intervalometer, EFCS, and the long-exposure modes ^[87] ^[88]. His cons were few: no articulating screen, the demands of full-frame on optics, and the high price ^[89]. Importantly, he pointed out that Nikon finally gave Canon competition in this arena, cheerfully stating “Let the games begin!” ^[90] in reference to the astro camera market. That “game” unfortunately saw only a few players (Canon Ra, Nikon D810A, and now OM System’s entry) before quieting down.

On forums like Cloudy Nights (a popular gathering for astrophotographers), discussions in 2025 reveal a mix of admiration and practicality regarding the D810A. Many users still using the D810A report excellent results and no major issues over years of use. Some technical debates have occurred about minor sensor artifacts (e.g. a phenomenon of “concentric rings” that can appear when calibrating images). One expert noted the D810A, like many Nikon DSLRs, has a slight black-level clipping in RAW that under certain flat-fielding conditions can produce circular color banding ^[91] ^[92]. But others chimed in saying they never encountered this in real use ^[93]. Overall, the consensus was that any such issues are either negligible or avoidable with proper technique.

When one user in 2025 explicitly asked if there’s a “compelling reason to buy a D810A now” given the availability of modded mirrorless, the community responded with thoughtful points ^[94]. If the goal is wide-field astro with fast lenses, the D810A’s optimized sensor stack (for corner performance) and lack of modification “quirks” is a plus. And while newer sensors have somewhat lower read noise, the difference may not be huge in finished images. A few experienced voices said if you can find a D810A at a decent price and you value a turnkey solution, go for it – you’ll get great images and you can always resell it (the resale value likely will remain strong as it gets more collectible). But if budget is tight, a used Z6 plus mod could get you 80-90% of the capability at half the cost, albeit with some inconvenience.

Astrophotography trend experts have also weighed in. There’s a recognition that “landscape astrophotography seems more popular than ever and less niche than 10 years ago,” as one person put it ^[95]. Indeed, the explosion of Milky Way photos on social media, and accessible star trackers, has brought many new folks into astro imaging. This broad interest might justify camera makers continuing to make specialty models. Yet the sales numbers are probably small, so it’s uncertain. That same discussion highlighted that it had been 6 years since the EOS Ra and 10 years since D810A, wondering if we’ll ever see another major manufacturer do an “A” model ^[96]. One member responded, “Your guess is as good as everyone else’s.” ^[97] In other words, it’s an open question.

Interestingly, one participant noted “Olympus recently released an astro version of their OM-1” ^[98] (meaning the E-M1 III Astro, which was July 2024), suggesting that if even OM Digital (a smaller player) did it, maybe there’s hope Nikon or Canon could again. Another countered that if you’re only doing astro, these special cameras aren’t cost-effective – better to get cooled astro cams ^[99]. It’s a valid point as mentioned above.

Where professionals stand in 2025: Many top astro photographers use a mix of gear. For wide-field nightscape shots, they might use a full-frame mirrorless (like a Sony A7 variant or Nikon Z) often with a fast prime lens. For deep-sky, they’re likely using cooled dedicated cameras on telescopes. Some, however, still champion DSLRs for certain purposes. Nikon’s own Ambassador (and astro photographer) Alan Dyer had used the D810A extensively for nightscapes and wrote about it in publications like Sky & Telescope. He found it excelled for things like capturing reddish nebulas in wide constellation shots that stock cameras would barely show ^[100]. In recent times, pros like him have also embraced cameras like the Z6 or Z7 (often modified).

It seems many recommendations in 2025 for someone starting astrophotography go like: if you already have a decent DSLR or mirrorless, consider getting it modified by a reputable service to broaden its astro capabilities (especially if it’s an older model you dedicate to astro). If you have money to spare and shoot Nikon, a used D810A is an easy way to get a no-compromise astro DSLR. If you shoot Canon, perhaps look for a used EOS Ra or get a newer EOS R5/R6 modified. For those heavily into deep-sky, jump to cooled astro cameras.

One cool expert quote comes from that forum debate: “There are things that a traditional camera can just do better, despite the lack of cooling,” said one user who tried using a cooled astrocam for wide shots ^[101]. He emphasized that combining astro with terrestrial photography is common, and for that “a traditional DSLR or mirrorless has far more pros than cons” ^[102]. This sentiment is essentially why cameras like the D810A existed and may yet have successors – they bridge two worlds.

Reviewers back in 2015 (DPReview, Imaging Resource) were impressed that Nikon addressed such a niche. DPReview’s initial article noted “the D810A brings improved light capture capabilities to the discipline [of astrophotography]…largest sensor to appear in a consumer astro camera” ^[103]. Imaging Resource’s William Brawley pointed out Nikon “took a page from Canon’s book” with the IR filter mod, and that aside from astro tweaks, the D810A retained all the prowess of the base D810 ^[104] ^[105]. He effectively suggested that if you didn’t mind the red tint, you were getting an amazing general camera too – though Nikon themselves discouraged general use.

Future Outlook: Astrophotography Gear and Recommendations

Looking ahead, what gear are professionals recommending and what might the future hold?

Many pros say “the best camera for astro is the one you have with you”, encouraging beginners to start with whatever DSLR/mirrorless they own and learn the techniques (tracking, stacking, etc.). But on the high end, there’s definitely movement towards specialized gear for specialized tasks. For serious deep-sky imaging, most will steer you to a cooled astro camera now (for example, a popular combo is the ZWO ASI2600MC Pro, a 26MP APS-C cooled sensor, which delivers superb results with less fuss in processing). However, for landscape and Milky Way photography, pros still love full-frame cameras with excellent high ISO. In 2025, common recommendations include: the Sony A7S III (if budget allows and 12MP is sufficient, its clean ISO 51200 is unparalleled), the Nikon Z6 II or Z7 II (Nikon’s sensors have great dynamic range and the bodies have robust build and IBIS – though IBIS is usually turned off on tripod astrophotography), and the Canon R6 Mark II or R5 (Canon closed much of the gap in sensor performance and offers great lens options like the RF 15-35 f/2.8 or RF 28-70 f/2 for night work).

Lenses are a big part of the gear discussion too. A decade ago, the go-to astro lens was often a Samyang/Rokinon 14mm f/2.8 (cheap and fast). Today, we have things like Sigma 14mm f/1.8, Canon RF 28-70 f/2, Nikon’s upcoming 58mm Noct f/0.95 (a bit exotic though), etc. Professionals emphasize fast glass and sharp corners for astro. The Nikon D810A, with its high resolution, will show aberrations in lesser lenses, so those using it often pair it with top optics (Nikon’s 14-24mm f/2.8 was a classic combo).

On the mirrorless vs DSLR question, many pros have moved to mirrorless for night work due to the easier focusing and often better sensitivity in newer sensors. But some DSLR holdouts remain – e.g. the Canon 6D (2012) was a cult classic for astro because of its low noise; even in 2025 you’ll find it recommended as a cheap used astro body (some say “get a used 6D and mod it” as a budget Hα solution). Nikon’s equivalent was the D750, another beloved camera for nightscapes. The D810A, being rarer, is like the connoisseur’s choice if you can find one.

What are professionals saying about the Nikon Z8/Z9 for astro? The Z9 (45MP stacked sensor) is more of a sports/wildlife camera, but it’s extremely capable in all areas. It can definitely do astro, though its lack of mechanical shutter means one must be cautious about sensor heating in long electronic shutter exposures (some users noted slight star deformation on the Z9 in very long exposures, possibly due to sensor self-heating causing noise reduction kicks – still being studied). The Z8 shares that sensor. These are heavy cameras though; an astro-landscape photographer might prefer a lighter body like a Z7 II or Z6 II on a trek.

One interesting trend: computational photography creeping into dedicated cameras. Olympus’s Live Composite we mentioned is one example. Canon has an “Astro” shooting mode in some recent APS-C bodies (like the EOS R7) that tweaks noise handling for star shots (and Star Focus on the EOS R3 that can detect and focus on stars, reportedly). If such features mature, they could mitigate some astro challenges (imagine a camera that can internally stack exposures or apply AI noise reduction tuned for astro). For instance, software like Sequator or Starry Landscape Stacker is often used by photographers now to align and stack nightscape images to reduce noise. If camera firmware could do that on the fly, it’d be a selling point.

Phones even do astrophotography by stacking multiple frames (Google Pixel’s astrophotography mode, Apple’s Night Mode stacking). Of course, phones can’t match a full-frame’s raw quality, but it shows the interest in shooting the night sky is widespread.

As of 2025, though, if someone asks “What gear should I get for astrophotography?” – the answers might include:

For deep-sky (through a telescope): Consider a cooled astro camera (ZWO, etc.) or if using a DSLR, at least get it modded for Hα. A sturdy equatorial mount is a must, guiding, etc. Specific cameras: maybe a modded Nikon D810A if you find one, or a modded Canon 5D IV/6D II, etc., but many would nudge you to dedicated astro cams for serious work.
For wide-field and landscape astro: A full-frame camera with excellent high ISO – e.g. Sony A7 IV or A7S III, Nikon Z6 II, Canon R6 II. Paired with fast wide lenses (e.g. 14-24mm f/2.8 or faster). If budget allows and Hα is desired, either get those modded or look for a used astro-special like D810A/Ra. A star tracker (like Sky-Watcher Star Adventurer or iOptron SkyGuider) is often recommended to allow longer exposures and lower ISO for cleaner results.
Also, don’t forget filters: Pros often use multi-band filters for light pollution or specific narrowband captures with DSLRs. For instance, Optolong’s L-eNhance or L-eXtreme filters let one shoot emission nebulae even under city skies by passing only nebula wavelengths. These can be used in front of lenses or as clip-ins (though clip filters depend on camera mount).

In the context of the D810A, a pro might say: If you own a Nikon D810A in 2025, it’s still a fantastic tool for what it does. Use it to capture nebula-rich regions – it will deliver results that stock cameras will envy. Combine it with good technique (shoot dark skies, proper calibration frames) and it’s as capable as ever. But also be aware that technology hasn’t stood still – newer cameras can complement it. For example, a D810A could be your deep-sky specialist, while a newer Nikon Z6 II could be your everyday/landscape camera that also does nice Milky Way shots. There’s no rule you can’t have both.

Finally, experts often mention the importance of processing. A great astro camera like the D810A will give you quality data, but making the most of it requires careful post-processing (stretching the histogram, balancing colors, stacking multiple exposures). In 2025, software like PixInsight, AstroPixelProcessor, Photoshop (with astro actions) are standard. The D810A outputs standard NEF files that work in all these – indeed Nikon updated Capture NX-D back then to handle D810A files with Astro NR ^[106].

To wrap up the expert perspective: the Nikon D810A is frequently cited as a high point in DSLR capability for astrophotography. As one forum user put it in a nostalgic tone: “It will undoubtedly be the camera of choice for starscape and time-lapse imagers because of its high-ISO capabilities and… super-fast wide-angle lenses [on] a full-frame body.” ^[107] That quote (which is Lodriguss’s, actually) held true for several years. Even now, a decade on, the D810A holds a special status. It represents a time when Nikon dared to build a very specific tool for a passionate community – and did a stellar job at it.

Final Thoughts

The Nikon D810A may no longer be in production, but in 2025 it remains a benchmark for what a manufacturer-tuned astrophotography camera can be. With its ability to natively capture the subtle reds of distant nebulae and produce low-noise, high-detail images of the night sky, the D810A still “shines” among the stars. It sits at an intersection of old and new: a DSLR with the soul of an astronomer, holding its ground in an era of mirrorless innovation and specialized astro rigs.

For photographers whose passion is the night sky, the D810A offers a unique combination of convenience and performance. There’s no need to send your camera off for modification or fiddle with clip-in filters that only partially recover what’s lost – it works out-of-the-box for the purpose it was intended. As many owners will attest, it’s a workhorse under the stars, reliably churning out images of nebulae and galaxies that grace magazine pages and astro forums.

However, the march of technology means we have many more choices now. The D810A is no longer the only game in town for serious astro imagers. Depending on one’s needs, a mirrorless body like the EOS Ra or a cooled astro camera might be a better fit. But there is something to be said for the self-contained versatility of a camera like the D810A. You can take it to a remote desert, shoot stunning Milky Way timelapses all night, and then use that same camera (with a proper white balance filter) to shoot a sunrise landscape – try doing that with a tethered astro CCD!

As astrophotography continues to grow in popularity, camera makers will hopefully take note. Whether we’ll see a “Z7a” or “EOS R5a” in the future remains uncertain, but enthusiasts are vocal about their desire for such models. In the meantime, the Nikon D810A lives on in the hands of dedicated users and on the used market listings where eager buyers leap at the chance to own one. It represents a pinnacle of DSLR engineering for the stars – truly, “the cosmos in epic detail,” as Nikon’s press release touted ^[108].

In the words of Jerry Lodriguss, “It’s nice to see Nikon finally giving Canon some competition in the astrophotography market… Let the games begin!” ^[109] That game may have seen only a few rounds (with Canon and Nikon each playing a card, and now OM System joining late), but the real winners are the astrophotographers who have more tools than ever to capture the splendor of the night sky. The Nikon D810A stands as a testament to what’s possible when a company listens to a niche community and commits to excellence. Even under the pale light of 2025’s technology, this DSLR still shines brightly, a star in its own right.
