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
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.
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 Moo.
Deep-sky sample images
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.
Professional-Grade Optical Design
Folded optical path design, compact and portable.
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.
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

New Upgraded Tripod. Stability, Leveled Up.
Adjustable Angle
More angle options for more shooting terrain
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.
Seestar gives advanced creators more freedom.
Open Expansion
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.

FAQ
Q: What can the new wide-angle camera on the S50 Pro do?
A: The S50 Pro features a 4K wide-angle camera with a 63° field of view, enabling:
1. One-Tap Milky Way Arch: Automatically captures and stitches a complete Milky Way arch—no need to manually plan stitching points.
2. Milky Way Time-Lapse: Record the movement of the Milky Way and watch it drift across the night sky.
3. Star Trail Photography: Use long exposures to capture striking circular star trails.
4. 8K Stitching: Create ultra-high-resolution wide-angle panoramas that stay sharp even when enlarged.
5. Wide-Field Live Stacking: Enhance wide-field image quality in real time for cleaner results, faster.
Q: What post-processing upgrades does the S50 Pro offer?
A: The S50 Pro now supports Smart Enhancement and one-tap image processing, including Star Reduction, Star Removal, and Noise Reduction.
Star Reduction makes stars smaller, bringing deep-sky objects such as nebulae and galaxies into clearer focus while preserving a natural star field for a cleaner, more refined image. Set Star Reduction to 100% to enable Star Removal, which removes stars from the image and highlights the textures, contours, and faint details of deep-sky objects. Noise Reduction is automatically applied in Smart Enhancement.
Q: What is the S50 Pro’s one-tap plan mode feature?
A: Based on your target and shooting conditions, Seestar can quickly generate a shooting plan and carry it out automatically. Even if you are unsure what to shoot or how to set the parameters, smart recommendations help you get started with less manual setup and fewer repeated steps.

A: Telescope Network lets you remotely control the S50 Pro for imaging. You can also share or transfer device access, and batch-export photos after a session. Capture and access your images even when the device is not by your side—for a more flexible everyday experience.
Q: How is the S50 Pro tripod different from the S50 tripod?
A: The S50 Pro features a new two-section tripod with two adjustable leg angles. It supports a wider adjustment range, adapts flexibly to different terrain, and provides a more stable shooting experience.
Q: How much internal storage does it have?
A: The S50 Pro has 128 GB of internal storage, with approximately 100 GB available for use.
Q: I already own an S30 Pro. Is it worth upgrading to the S50 Pro?
A: The S30 Pro is a portable all-rounder for a wide range of shooting scenarios. The S50 Pro is built for deep-sky imaging, with a larger aperture, a more capable tracking system, and richer image detail.
If portability and versatile everyday shooting are your priorities, the S30 Pro remains an excellent choice. If you want to capture fainter deep-sky objects and pursue greater imaging detail, the S50 Pro is the better upgrade.

Handle with care.
Seestar smart telescope is a precision optical and electronic instrument. Avoid drops, impacts, or strong shocks, which may cause damage.
Image results may vary.
Imaging performance depends on environmental conditions such as light pollution, atmospheric transparency, parameter settings, and stacking duration. Actual results are subject to real‑world shooting conditions.
[1] At 1× magnification, both the telephoto and wide‑angle cameras capture images at 4K (3840 × 2160) resolution. Resolution decreases at 2× and 4× magnification. The real‑time live preview stream for both cameras is 1080P.
[2] Milky Way imaging requires dark‑sky conditions. In areas with significant light pollution, Milky Way details may be limited or not visible. Results depend on on‑site observing conditions.
[3] NFC functionality requires a compatible smartphone. Support varies by device and model—please refer to your phone's specifications.
To use NFC, ensure the telescope is powered on, the phone is unlocked, and Wi‑Fi, Bluetooth, NFC, and GPS are enabled on your phone.
NFC sensitivity varies by device due to antenna placement. Locating your phone's NFC sensing area may improve detection.
If the Wi‑Fi name is changed, NFC information must be updated manually for NFC to work properly.
[4] Due to system usage and storage allocation, available capacity may vary. System updates may affect storage allocation. Please refer to the actual available capacity on your device.
[5] Under ambient temperatures above 25°C, with Alt‑Azimuth Mode and Telephoto Sensor Stargazing Mode enabled, the battery provides up to 9 hours of runtime. Data provided by the ZWO laboratory for reference only. Actual performance may vary.
Data provided by ZWO Laboratory for reference only; actual performance may vary.
[6] 60 s long exposures are supported only in Equatorial Mode and are not available in Alt‑Azimuth Mode. Accurate polar alignment is required in Equatorial Mode to ensure precise tracking. Inaccurate alignment may reduce imaging performance.
[7] A solar filter must be installed when observing the Sun. Never allow the main camera to observe the Sun directly, as this may cause permanent damage to the device.
[8] The Smart Enhancement feature optimizes noise in actual astrophotographic images and enhances the stars captured in those images. It works like beautification applied to existing photos and does not generate AI‑created images. This product is an intelligent astronomical telescope, and all images are authentic captures without AI‑generated content.
[9] Wi‑Fi transmission range is measured under ideal conditions. ZWO Laboratory testing shows a range of up to 10 meters in an open outdoor environment without interference. Actual range depends on real‑world conditions.
[10] Sudden changes such as cloud cover, rain, or strong winds may prevent task completion. The device does not automatically power off in these situations. Please confirm weather conditions before scheduling an imaging plan.
[11] Telescope Network Remote Access is available for a limited‑time free trial during the beta period.
