ZWO Seestar S50 Pro smart telescope review
ZWO's best pro smart telescope to date is perfect for astronomy and solar imaging, with a price to match.
The ZWO Seestar S50 Pro, released on August 25, 2026, is a smart telescope designed for both astronomy and solar observations. The device ships with all necessary accessories, eliminating the need for additional purchases. Controlled through the Seestar app on a smartphone, the S50 Pro offers automatic slewing and autofocused views of celestial objects like galaxies, nebulas, and star clusters.
While it sometimes requires manual adjustment with the on-screen joystick, the Pro version boasts double the storage capacity (128 GB compared to 64 GB) and a higher resolution (4K instead of Full HD), with a claimed extended battery life of nine hours. The S50 Pro measures 5.7 x 10.6 x 5.4 inches (146 x 270 x 138 mm) when fully packed, weighing 8.6 pounds (3.9 kilograms), including a compact carbon fiber tripod.
The device operates through the Seestar app, and its design features a sleek, glossy plastic casing. The telescope has a 3/8-inch tripod thread for compatibility with most photographic tripods but comes with a small carbon fiber tripod. Its automatic alignment and tracking, live stacking feature, and push-on solar filter enable the observation of various celestial objects, including the Dumbbell Nebula, the Andromeda Galaxy, and sunspots.
