Seestar S50 Pro

Purpose-built for portable astrophotography.

The folded optical design keeps the telescope compact while the integrated alt-azimuth mount and upgraded tripod make it quick to carry outside, level and start using.

The Pro generation

Five major upgrades, built into one Seestar.

Higher-resolution dual imaging, upgraded four-element optics, a wider native deep-sky field, longer runtime and more internal storage move the S50 Pro beyond the original all-in-one formula.

Five major Seestar S50 Pro upgrades overview

Professional-grade imaging

Two 4K cameras, two ways to explore the sky.

The telephoto camera records fine detail in deep-sky targets through the 50 mm APO optical system. The integrated wide-angle camera captures a much broader 63° view for Milky Way, nightscape, star-trail and time-lapse work—and helps make target finding more intuitive.

Seestar S50 Pro dual-camera imaging system

Simple from the first session

Choose a target, tap GOTO, start capturing.

After positioning and connection, the Seestar app can locate a target, slew the telescope, track it and begin imaging. The integrated workflow removes the need to assemble a separate telescope, mount, camera, controller and capture computer.

Three-step Seestar S50 Pro smart telescope workflow

Four observing worlds

Deep sky, the Milky Way, Sun and Moon, plus daytime scenery.

One compact instrument can move from nebulae and galaxies to wide nightscapes, lunar and filtered solar imaging, wildlife and distant landscapes. Dedicated modes keep the controls relevant to the subject in front of you.

Seestar S50 Pro deep-sky, Milky Way, solar, lunar and scenery modes

50 mm aperture

More light and resolving power for fine celestial detail.

A 50 mm aperture has nearly three times the light-gathering area of a 30 mm aperture. Combined with the large 1/1.2-inch telephoto sensor, it is designed to reveal faint structures in deep-sky objects while retaining detail on the lunar surface and in safely filtered solar targets.

DSO mosaic stitching

Expand the frame without giving up the telephoto view.

Mosaic capture automatically joins multiple telephoto frames into a broader composition. It is useful for large nebulae and target groups that extend beyond a single 2.8° portrait field, with stitched output available at up to 8K resolution.

Seestar S50 Pro deep-sky mosaic stitching example

Redesigned optical system

Four-element APO optics with ED glass.

The telephoto channel uses a four-element apochromatic lens with extra-low-dispersion glass. The design is intended to control chromatic aberration and render smaller, cleaner stars across the 4K field while a folded light path keeps the body portable.

Seestar S50 Pro optical image quality and star rendering

4K dual-lens system

Detailed deep-sky imaging and expansive wide-field capture.

Both channels record 2160 × 3840 images at 1×. The telephoto camera uses an 8.3 MP OmniVision OS08B10 sensor behind the 260 mm f/5.2 optical system, while the 8.3 MP IMX586 wide camera covers a 63° portrait field through a 6 mm f/1.75 lens.

Smart GOTO

A large celestial database, ready to point and track.

Search or select a target in the Seestar app and the telescope automatically positions itself, begins tracking and guides you into capture. The database includes more than 80,000 deep-sky objects and 600,000 stars.

Seestar app smart GOTO target database and automatic tracking

In-app finishing tools

One-tap enhancement or more deliberate editing.

Smart Enhancement can apply noise reduction and refine the captured image. Additional controls include star reduction, star removal, crop, brightness, contrast and saturation, allowing a polished result without moving every session to a desktop editor.

Starry Sky Mode

Wide-field Milky Way images, captured with an integrated smart telescope.

The 63° wide camera extends the S50 Pro beyond traditional narrow-field smart telescopes. It supports Milky Way live stacking, time-lapse, panoramic stitching and nightscape workflows from the same Seestar app.

Flexible framing

Build the Milky Way composition around the landscape.

Multiple stitching layouts help you choose between a broader field and a more focused section of the galactic core. The visual planning interface shows the intended frame before the sequence begins.

Seestar S50 Pro Milky Way stitching and framing options

One-tap Milky Way arch

Automatic panoramic stitching with output up to 8K.

The S50 Pro can automate the sequence needed to create a complete Milky Way arch, then combine the frames into a large panoramic result.

Freeze the Ground

Tracked stars and a stable foreground in the same nightscape.

Seestar can separate the foreground from the moving sky, keep the landscape fixed and process it independently. The freeze duration is adjustable, helping retain sharp ground detail while the camera tracks the stars.

Seestar S50 Pro Freeze the Ground nightscape processing

Constellation recognition

Identify the pattern, then send the telescope to the target.

Constellation lines and names can be overlaid in the app, helping new users understand the sky they are seeing and move directly from recognition to GOTO positioning.

Seestar app intelligent constellation recognition and labels

Star trails

Turn a long exposure sequence into a dynamic sky video.

Star Trail mode records the apparent rotation of the sky and can automatically assemble the captured sequence into a moving result as well as a finished still image.

Circular star trails photographed with Seestar S50 Pro

Sun, Moon and scenery

Keep using it when the deep sky is not the subject.

Capture lunar surface detail, safely filtered sunspots and eclipses, or use the telephoto channel for distant scenery, wildlife and events. The supplied magnetic solar filter must always be installed before the main camera is directed at the Sun.

Solar, lunar, eclipse and daytime scenery imaging with Seestar S50 Pro

Longer sessions

10,000 mAh battery and 128 GB eMMC storage.

The internal battery is rated for up to nine hours in ZWO laboratory conditions. Approximately 100 GB of the 128 GB storage is available after system allocation, giving longer imaging plans more room to run.

Seestar S50 Pro 10,000 mAh battery and 128 GB storage

Up to nine hours was measured by ZWO above 25°C in Alt-Azimuth Mode with telephoto stargazing enabled. Temperature, dew-heater use, wireless activity and operating mode can reduce actual runtime.

Plan Mode

Set the night’s targets and let Seestar work through them.

Plan Mode can recommend a sequence using the selected targets and observing conditions. Once confirmed, the telescope follows the schedule automatically rather than requiring attention at every change.

Seestar S50 Pro all-night Plan Mode workflow

Multi-target capture

Move automatically from one celestial object to the next.

A scheduled plan can change targets, position the telescope and continue capturing through the night, making better use of long clear windows.

Seestar S50 Pro one-tap multi-target shooting plan

Equatorial Mode support

Longer exposures with the effects of field rotation reduced.

The S50 Pro can operate in Equatorial Mode with suitable support and accurate polar alignment. Its precision drive system is designed for near-zero backlash, smoother corrections and more efficient tracking. Exposures of up to 60 seconds are available only in Equatorial Mode.

Seestar S50 Pro Equatorial Mode precision tracking

A suitable wedge or equatorial support is required for Equatorial Mode and is not listed among the standard in-box items.

Upgraded tripod

Two leg angles for more stable placement.

The included two-section tripod offers two adjustable leg angles, allowing a broader stance and more flexibility across different surfaces and observing setups.

Seestar S50 Pro upgraded two-angle tripod

AI assistant

Ask for a target or help with the next step.

The app assistant can help with target discovery, celestial information, imaging guidance and operation. Name the object you want to see and it can search for it, begin GOTO positioning and move into capture.

Telescope Network

Remote access when the telescope is somewhere else.

Telescope Network can provide remote control, device-access sharing and batch photo export. This can separate the imaging location from the place where a session is monitored or reviewed.

Seestar Telescope Network remote-control feature

ZWO lists Telescope Network Remote Access as a beta feature with a limited-time free trial. Future availability or charges may change.

Open expansion

ASCOM Alpaca support for advanced workflows.

Support for the open ASCOM Alpaca protocol allows compatible third-party astronomy software, including N.I.N.A., to communicate with the S50 Pro. This gives experienced users a path beyond the standard app-led workflow.

Seestar S50 Pro open ASCOM Alpaca software support

Field-of-view comparison

Where the S50 Pro sits between the S50 and S30 Pro.

The telephoto channel’s 2.8° portrait field is substantially wider than the original S50’s 1.46° field while retaining a 50 mm aperture. The S30 Pro reaches a wider 4.6° telephoto field, but its smaller 30 mm aperture prioritises portability and framing over the S50 Pro’s light-gathering and resolving power.

Field-of-view comparison between Seestar S50 Pro, S50 and S30 Pro

Is the S50 Pro right for you?

A stronger fit when deep-sky detail matters most.

The S50 Pro is the model to choose when you want the convenience of a Seestar but do not want to step down from a 50 mm aperture to gain modern dual-camera features.

Choose the S50 Pro for

Fainter deep-sky targets, finer lunar and solar detail, a wider native telephoto field than the original S50, 4K output from both cameras, long planned sessions, and the ability to add Equatorial Mode or ASCOM Alpaca workflows later.

Consider the S30 Pro instead when

Minimum carry weight and the widest telephoto field are more important than 50 mm aperture. The S30 Pro is the smaller 1.65 kg travel-focused option; the S50 Pro main unit weighs 2.8 kg and is aimed more directly at deep-sky performance.

Consider the original S50 when

Your priority is an accessible 50 mm Seestar for conventional deep-sky, lunar and solar imaging and you do not require the Pro model’s 4K dual-camera system, 2.8° telephoto field, 128 GB storage or longer battery rating.

Frequently asked questions

Before your first clear night.

What can the S50 Pro wide-angle camera capture?

The 4K wide camera covers a 63° portrait field and supports Milky Way arches, Milky Way time-lapse, star trails, wide-field live stacking and panoramic output up to 8K. It also assists the telephoto system with target location and tracking.

Does the Seestar S50 Pro use a Sony IMX585 telephoto sensor?

No. ZWO specifies the telephoto sensor as the OmniVision OS08B10, with a 1/1.2-inch format, 2.9 μm pixels and 8.3 MP resolution. The wide-angle camera uses the Sony IMX586.

What does Smart Enhancement do?

Smart Enhancement processes an image that the telescope has actually captured. It can reduce noise and refine stars; the editing tools also provide star reduction and star removal. ZWO describes this as non-generative processing rather than creating an artificial sky image.

Can it take 60-second exposures?

Yes, but 60-second exposures are supported only in Equatorial Mode. A suitable equatorial support and accurate polar alignment are required; inaccurate alignment can reduce tracking performance.

How much storage is actually available?

The telescope contains 128 GB of eMMC storage. After the operating system and reserved allocation, approximately 100 GB is available. Future system updates can change the usable amount.

Will the battery always last nine hours?

Nine hours is an “up to” laboratory figure measured by ZWO above 25°C in Alt-Azimuth Mode with telephoto stargazing enabled. Cold conditions, dew-heater use, operating mode and other loads can shorten real-world runtime.

Is the supplied tripod different from the original S50 tripod?

Yes. The S50 Pro includes a two-section tripod with two selectable leg angles. This gives it a wider adjustment range and lets it use a broader stance when the surface or setup benefits from it.

Can the S50 Pro be controlled by third-party astronomy software?

It supports the open ASCOM Alpaca protocol and can connect with compatible software such as N.I.N.A. Compatibility and available functions can depend on the software version and Seestar firmware.

Can it safely photograph the Sun?

Yes, only with the supplied magnetic solar filter correctly installed. Never point the main camera at the Sun without the solar filter, as unfiltered sunlight can permanently damage the telescope.

What affects the final astrophotography result?

Light pollution, clouds, atmospheric transparency, wind, focus, alignment, target altitude, exposure settings and total stacking time all matter. Milky Way detail in particular requires suitably dark conditions; no telescope can recover detail that local sky brightness completely overwhelms.

Important use notes

Always fit the magnetic solar filter before aiming the main camera at the Sun.
At 1×, both cameras capture 3840 × 2160 output; resolution reduces at 2× and 4× digital magnification, and the live preview stream is 1080p.
NFC setup requires a compatible phone with NFC, Wi-Fi, Bluetooth and location services enabled. NFC performance varies with phone antenna position.
Check the weather before leaving Plan Mode unattended. Sudden rain, clouds or strong wind can interrupt a task, and the telescope does not automatically power off for changing weather.
Handle the telescope as a precision optical and electronic instrument. Avoid impact, drops and strong shock.
