ZWO Seestar S50 Pro Smart Telescope

The Next Generation of All-in-One Smart Astronomy

The ZWO Seestar S50 Pro takes the simplicity of smart telescopes to a new level, combining advanced astronomical optics, dual-camera imaging, intelligent tracking and computational photography into a compact, portable system.

Designed for both beginners and experienced observers, the Seestar S50 Pro allows you to explore the night sky, capture stunning deep-sky images, photograph the Moon and Sun, and enjoy wide-field views — all from a single, highly integrated instrument.

At its heart is a 50 mm f/5 apochromatic telephoto system featuring a sophisticated 4-element APO optical design with ED glass, delivering improved optical correction and high-quality images. The S50 Pro also incorporates a dedicated wide-angle camera, giving you an expansive 63° field of view for large celestial objects, landscapes and wide-field imaging.

With 8.3 MP imaging on both cameras, 128 GB of internal storage, a 10,000 mAh battery and support for Equatorial Mode, the S50 Pro is built for extended observing and imaging sessions without the complexity of traditional astrophotography equipment.

Product Highlights

Dual-Camera Imaging System

The Seestar S50 Pro combines two dedicated imaging systems:

• Telephoto Camera: 50 mm aperture, 260 mm focal length, 2.8° field of view
• Wide-Angle Camera: 3.4 mm aperture, 6 mm focal length, expansive 63° field of view
• Both cameras feature 8.3 MP resolution

Switch between detailed astronomical imaging and expansive wide-field views from the same compact instrument.

50 mm 4-Element APO Optics

The telephoto optical system uses a 4-element apochromatic lens incorporating ED glass, designed to provide excellent colour correction and high-quality imaging across the field.

The 260 mm focal length corresponds to an impressive 880 mm equivalent focal length, making the S50 Pro particularly well suited to capturing galaxies, nebulae, star clusters and other deep-sky targets.

Wide-Field Photography

The integrated wide-angle camera provides a 63° field of view, making it ideal for capturing large areas of the night sky, Milky Way scenes, expansive nebulae and terrestrial landscapes.

With a 35 mm equivalent focal length, the wide-angle camera provides a completely different imaging perspective from the telephoto system.

Built-In Astronomical Filters

The Seestar S50 Pro features an integrated filter system including:

• UV/IR Cut Filter
• Dual-Band Light Pollution Filter — OIII 30 nm / Hα 20 nm
• Dark Frame Filter

The filters are designed to optimise imaging for different astronomical targets and observing conditions.

Magnetic Solar Filter Included

A dedicated magnetic solar filter is included, allowing the S50 Pro to be used for solar imaging when the filter is correctly installed.

Never observe or photograph the Sun without the supplied solar filter correctly fitted.

128 GB Internal Storage

The S50 Pro features 128 GB of eMMC internal storage, providing approximately 100 GB of usable space after system and storage requirements.

This provides ample room for storing astronomical images and videos during extended observing sessions.

10,000 mAh High-Capacity Battery

The upgraded 10,000 mAh battery provides up to 9 hours of runtime under ZWO's stated test conditions, making the S50 Pro well suited to long observing and imaging sessions away from mains power.

Alt-Azimuth & Equatorial Modes

The S50 Pro operates on an Alt-Azimuth mount and supports Equatorial Mode, providing greater flexibility for astronomical tracking and imaging.

The mount offers a slew range of 1× to 1440×.

Compact and Portable

Despite its sophisticated optical, imaging and tracking systems, the main unit weighs only 2.8 kg.

The supplied protective case and tripod make the S50 Pro easy to transport to your garden, balcony, observing site or dark-sky location.

Imaging & File Formats

The Seestar S50 Pro supports both JPEG and FITS image formats, making it suitable for casual astrophotography as well as more advanced post-processing workflows.

Video can be recorded in:

• MP4
• AVI

The combination of FITS support and integrated astronomical imaging makes the S50 Pro particularly attractive to users who want to move beyond simply viewing images and begin experimenting with their own astrophotography processing.

A Complete Observatory in Your Backpack

Traditional astrophotography can involve a telescope, camera, mount, guiding system, filters, focuser, cables and considerable setup time.

The Seestar S50 Pro brings many of these components together in one intelligent, portable instrument.

With advanced APO optics, dual cameras, integrated filters, automated tracking, Equatorial Mode support, generous internal storage and a high-capacity battery, the S50 Pro is designed to make capturing the night sky remarkably simple.

Set it up. Point it at the sky. And start exploring.
