Description
ZWO Seestar S50 Pro All-in-One Smart Telescope
Professional-Grade Astrophotography Made Easy
The ZWO Seestar S50 Pro is an advanced all-in-one smart telescope designed to make astrophotography accessible to beginners while offering powerful imaging features for experienced astronomy enthusiasts. Combining a 50mm aperture apochromatic optical system, dual 4K cameras, automated object tracking, and intelligent image processing, it makes capturing the wonders of the universe easier than ever.
50mm Aperture and Advanced APO Optics
The S50 Pro features a four-element apochromatic (APO) optical system with extra-low dispersion (ED) glass, a 50mm aperture, and a 260mm focal length at f/5.2. This optical design helps minimize chromatic aberration and produces sharp stars with well-defined details. Its larger aperture also gathers more light than smaller smart telescopes, helping reveal faint structures in nebulae, galaxies, and other deep-sky objects.
Dual 4K Camera System
The S50 Pro combines two 8.3-megapixel cameras to support different types of imaging. The telephoto camera features a large 1/1.2-inch sensor for capturing detailed deep-sky objects, while the wide-angle camera offers a 63° field of view for expansive views of the starry sky. Both cameras support 4K UHD image capture at 1× magnification, allowing the telescope to handle both detailed astronomical imaging and wide-field photography.
Automated Astronomy at Your Fingertips
Forget the complicated setup associated with traditional astrophotography. Using the Seestar app, you can select a celestial object and let the telescope automatically locate, track, and capture it. Its extensive object database and intuitive controls help you explore nebulae, galaxies, star clusters, the Moon, and the Sun with minimal manual adjustment.
Smart Imaging and Image Processing
The S50 Pro includes built-in filters to help improve astronomical images. Its UV/IR-cut filter reduces unwanted infrared interference, the dual-band light-pollution filter helps suppress unwanted background light, and dark-frame processing reduces noise in long exposures.
After capturing images, you can use the app's image-processing tools to adjust brightness, contrast, and saturation, reduce noise, reduce star sizes, or remove stars to emphasize the structures of nebulae and galaxies. These tools help you refine your astrophotographs without requiring a complicated external editing workflow.
Capture the Milky Way and Wide-Field Panoramas
Beyond deep-sky imaging, the S50 Pro offers dedicated wide-field photography features. Its wide-angle camera supports Milky Way photography, star-trail capture, and time-lapse recording. Mosaic stitching combines multiple images to create a wider view, with panorama output reaching up to 8K resolution. For the best Milky Way results, a dark observing location with minimal light pollution is recommended.
Automated Observation Planning
With Plan Mode, the S50 Pro can generate an observation plan and automatically capture multiple celestial targets in sequence. This allows you to spend less time managing equipment and more time enjoying the night sky. Equatorial Mode also supports longer exposures, including exposures of up to 60 seconds when properly aligned, helping improve tracking for demanding astrophotography sessions.
Explore the Sun, Moon, and Daytime Scenes
The S50 Pro is not limited to nighttime astronomy. It can capture lunar surface details, sunspots, and solar or lunar eclipses. Its telephoto imaging system can also be used for daytime subjects such as distant landscapes, birds, and other objects. The supplied solar filter must be installed before observing or imaging the Sun. Never point the telescope at the Sun without the solar filter.
Long Battery Life and Generous Storage
A built-in 10,000mAh battery provides up to nine hours of operation under specified test conditions, making the telescope suitable for extended observing sessions. Its 128GB internal storage offers approximately 100GB of usable space for captured images and videos. With Wi-Fi, Bluetooth, and USB Type-C connectivity, the S50 Pro combines portability with convenient wireless control and file management.
A Complete, Portable Smart Telescope
The Seestar S50 Pro integrates its optical system, cameras, tracking mechanism, and smart controls into one compact instrument. The package includes a tripod and a solar filter, allowing you to get started with automated astronomy without assembling a traditional telescope and separate astrophotography camera system.
The ZWO Seestar S50 Pro is an excellent choice for anyone looking for a portable, easy-to-use smart telescope that combines automated observation with versatile astrophotography capabilities
Seestar S50 vs. S50 Pro
The most visible change is the move from one telephoto camera to a dual-camera system. The S50 Pro telephoto camera uses a 1/1.2-inch, 8.3 MP sensor and captures 4K UHD images at 1x. Its 2.8-degree field of view is substantially wider than the S50's 1.46-degree view, making targets such as the Andromeda Galaxy and Orion Nebula easier to frame with more of their surrounding environment.
