ZWO Seestar S50 Pro Smart Telescope for Astrophotography

ZWO Seestar S50 Pro Smart Telescope

50 mm Aperture. The Universe, Revealed.

The Seestar S50 Pro is a logical further development of the popular smart telescope. It is a mobile, fully automatic platform for astrophotography with integrated optics and camera. The Seestar is a fully automatic astrophotography telescope that automatically performs complex tasks such as positioning, focusing, tracking, stacking, etc.



Pro Performance. Built to Explore.

Five major upgrades compared to the predecessors, one powerful new Seestar:

Large 50 mm aperture reveal sharper details than the 30 mm lens of the S30 Pro.
4K dual lens system for a finer, clearer view, compared to the S50.
Now wide-field astrophotography is possible, captured in one tap.
One-tap post-processing, advanced editing.
10,000 mAh battery allows for 9 hours of imaging.



Professional-Grade Imaging - All-in-One, Ready for More.

Traditional astrophotography often requires multiple devices - such as a telescope, equatorial mount, and camera - along with complex wiring and setup.

Seestar integrates its core imaging system into one compact device for easy carrying and fast setup. Whether you´re on a family trip or embarking on your next outdoor creative adventure, capture the beauty of the universe whenever inspiration strikes.



Just Three Steps - Create Cosmic Shots in Seconds

Step 01: Power on and connect instantly via NFC

Step 02: Choose a shooting mode and target

Step 03: Output a 4K masterpiece with one tap



From Deep-Sky to Everyday Viewing, Capture It All

Four modes cover the universe and the world around you, bringing every discovery into clear view.



Modes for Celestial and Terrestrial Imaging

The modes were made in regard of the specific properties of the subjects they are used for.



50 mm Large Aperture - Sharper Detail, Greater Light-Gathering Power.

With nearly three times the light-gathering area of a 30 mm aperture, the 50 mm aperture delivers faster light collection and greater optical resolving power. Paired with a 4K 1/1.2-inch large-format sensor, it reveals rich detail - from faint structures in deep-sky objects to the intricate textures of the Sun and Moon.



Deep-Sky Sample Images

This small telescope is a serious deep-sky imaging system, covering larger areas as well as showing details and dimmer areas.



DSO Mosaic Stitching

Telephoto mosaic capture stitches a wider frame while preserving telephoto detail. It expands the field of view and can output up to 8K high-resolution images. For deep-sky targets, lunar surfaces, and other detail-rich scenes, it captures both finer details and a broader view.



Professional-Grade Optical Design

The folded optical path design makes the S50 Pro compact and portable, the high-quality optics deliver great images.



Elaborated Lens, Helpful Filters

4-Element Apochromatic Lens:
Engineered to minimize chromatic aberration, the 4-element apochromatic lens (with an Extra-low Dispersion glass) delivers rounder, sharper stars and clean, neutral blacks.

The result is a night sky rendered with clarity and balance - true to what the eye expects and the universe deserves.

Triple Filter System:
Astronomical light pollution filter reduces interference from moonlight and urban light pollution, especially when photographing emission nebulae.
Dark frame filter subtracts noise from long exposures.
IR-cut filter blocks infrared interference for cleaner astrophotography.



4K Dual-Lens - Ultra-Clear Imaging to See Deeper and Capture Wider

Telephoto and wide-angle cameras work together, both supporting 4K UHD resolution.
- The telephoto camera features a 1/1.2" large sensor for clearer deep-sky object details.
- The wide-angle camera records a broader starfield, keeping the whole scene in frame.
The dual-camera system balances deep-sky capture with wide-field astro shooting.



Massive Object Database, One-Tap Smart Stargazing.

Select a target in the app and tap GOTO. Seestar automatically locates, tracks, and captures it, delivering cosmic shots in minutes.



One-Tap Post-Processing, Advanced Editing.

Get a polished result with one tap, or take more control with advanced editing tools including star reduction, star removal, cropping, brightness, contrast, noise reduction, saturation, and more. Refine every detail and bring your imagined shot to life.






Pro-Level Milky Way Shots - Captured in One Tap

You can capture the Milky Way as a normal image or in a timelapse video, but also show dynamics by using star trail photography.



More Freedom to Frame, a Wider View

Starry Sky Mode supports multiple Milky Way stitching options.



One-Tap Milky Way Arch, 8K Masterpieces Instantly

This image of the Milky Way is a mosaic, showing a huge amount of detail over the extremely wide field of view.



Freeze the Ground, Two Worlds in Perfect Focus

Intelligently detects and locks the foreground landscape, processing it separately from the sky. Landscape freeze duration can be customized. Stars stay sharp during tracking while the landscape remains clear and natural, creating crisp, striking astro landscapes.



Intelligent Constellation Recognition

Recognize constellation lines and labels with one tap, then quickly GOTO the target.

Even beginners can easily find their own constellation.



Star Trail Masterpieces, Effortless.

Long-exposure star trail captures can be automatically turned into dynamic videos, showing the night sky moving over time for more impactful results.



Sun. Moon. Action.

Seestar makes it easy to capture sunspots, lunar surface details, and rare celestial events such as solar and lunar eclipses. More than a pocket observatory for the night sky, it also serves as a super-telephoto viewing camera for daytime use. From birdwatching and distant landscapes to rocket launches, Seestar is ready to capture it all.



Long Battery Life. Big Storage. Keep Inspiration Going.

Upgraded to a 10,000 mAh battery, with up to 9 hours of stargazing.

More peace of mind for all-night observation and more fun for camping under the stars.



Plan Mode - Let Seestar Handle Your Night Sky Workflow

Effortless all-night shooting.

Set it once and leave it to run all night.



Generate a shooting plan with one tap

Multi-Target Continuous Shooting

Automatically switches targets by plan to capture more celestial objects efficiently.



Equatorial Mode

Offsets the effect of Earth´s rotation when tracking celestial targets, enabling stable tracking and longer exposures so objects stay "still" in the frame.

Seestar S50 Pro features a precision drive system with near-zero backlash. Combined with Equatorial Mode, it delivers faster, smoother tracking and fine adjustments for a significant boost in imaging efficiency.



New Upgraded Tripod. Stability, Leveled Up.

Adjustable Angle

More angle options for more shooting terrain

Stable Support

More balanced three-point load distribution for a steadier setup



AI Assistant - Your Stargazing Friend

The AI assistant helps with observation, imaging, celestial knowledge, and operation guidance.

Just say the celestial target you want to see. It quickly searches the target, performs GOTO positioning, and starts capture, making stargazing more natural and efficient.



Remote Control - Connect to Your Starry-Sky Device from Anywhere

Keep remote devices under control so weather, location, and time no longer limit your imaging efficiency.

Connect remotely to observe, capture, and organize files with ease. Whether your local sky is cloudy, heavily light-polluted, or in daylight, you can connect to a device in a better observing location and keep creating.



Advanced Features. Go Further.

Open Expansion - Seestar gives advanced creators more freedom.

Supports the open ASCOM Alpaca protocol and connects to third-party astronomy software such as N.I.N.A., expanding automated observation and advanced imaging workflows.
From a smart stargazing device to an open astronomy creation platform.
