Luxembourg implements EU drone rules by risk category (Open, Specific, Certified), with no legal distinction between recreational and commercial pilots. Open category comprises three subcategories—A1, A2, and A3—defined by drone weight and proximity to people, with most everyday flights falling under Open. Maximum altitude is 120 meters above ground, drones must stay in visual line of sight (about 500 meters), FPV flights require a spotter, and night flights are allowed in Open if lighting and rules are followed. Registration is mandatory for most operators: drones over 250 g must be registered as a UAS Operator, lighter drones with cameras or

On 1 July 2015, SACAA implemented Part 101, introducing licensing, drone registration, operating certificates, and safety restrictions for drones nationwide. Drones are illegal to fly within 10 kilometers of airports, helipads, or airfields without written SACAA authorization and ATC coordination. The general altitude limit is 120 meters (400 feet) above ground level, with hobby drones often advised to stay around 45 meters unless otherwise approved. Pilots must maintain visual line of sight at all times, typically within about 500 meters of the operator. A 50-meter separation from people, buildings, and roads applies; flights over crowds or private property without consent

The General Directorate of Civil Aviation (SHGM) is the primary regulator for drones in Turkey, maintaining the national drone registry, issuing permits, and coordinating enforcement, while the State Airports Authority (DHMİ) manages airspace near airports. Turkey classifies drones into İHA0 (500 g–4 kg), İHA1 (4–25 kg), İHA2 (25–150 kg), and İHA3 (above 150 kg), with drones under 500 g largely exempt from registration and licensing. Drones ≥500 g must be registered in the SHGM system (iha.shgm.gov.tr) and pilots must be registered, with foreigners using a special foreign-operator process rather than direct online registration. For recreational use, drones under 4 kg

StellaLyra 8″ f/6 and Apertura AD8 are both 203 mm (8″) parabolic-mirror Dobsonians with a 1200 mm focal length (≈ f/6). Vaonis Vespera II uses a 50 mm f/5 quadruplet apochromatic refractor with a built‑in camera and a Sony IMX585 sensor (8.3 MP). The StellaLyra and Apertura are manual Dobsonians on wooden alt-az mounts, while the Vespera II is a motorized GoTo system with auto‑initialization and tracking. The Vespera II offers a native field of view around 1.6° × 0.9°, enabling large targets to be captured on its screen. Visual observing with the 8″ Dobs delivers real-time eyepiece views, whereas

The Celestron NexStar 8SE is a 203 mm Schmidt-Cassegrain with a GoTo computerized fork mount and f/10 optics, delivering bright, detailed views but at a high price for beginners. The Sky-Watcher 8-inch Dobsonian is a 203 mm reflector on a manual alt-azimuth mount with f/6, offering a large light bucket at low cost but no tracking. The Celestron NexStar Evolution 9.25 has a 235 mm aperture, premium Go-To fork mount with built-in battery and WiFi app, but is heavy (~28 kg) and expensive. The Sky-Watcher SkyMax 150 Maksutov-Cassegrain delivers high-power planetary detail with a 150 mm aperture and f/12, but
