Seestar Smart Telescope
A New Era of Astrophotography
Traditional astrophotography often requires a telescope, an equatorial mount, a dedicated astronomy camera and more, with complex wiring and setup. Seestar integrates the core imaging system into one lightweight device. Simply mount it on a tripod, power it on, and connect to the Seestar app to start imaging. From backyard stargazing to camping trips and family outings, capture the beauty of the universe wherever you go.
From Deep Sky Wonders to Everyday Moments. Capture It All.
Four imaging modes to bring the universe and everyday discoveries into clear view.

A Universe in Your Backpack
Travel Light. Explore the Night Sky.
From mountain campsites to faraway destinations, start your astrophotography adventure wherever you go.
Discover the Night Sky. Even in the City.
The built-in light pollution filters reduce interference from city lights. Capture the night sky right from your balcony or backyard!
Discover the Stars. Together.
Capture the Moon’s craters and distant nebulae with your family. Turn an evening under the stars into a shared discovery.
For the Stargazer in Your Life.
Give them a closer look at the universe—and share the wonder of what comes into view.
80,000+ Celestial Objects. A Universe to Explore.
Select a target in the Seestar app and tap GOTO. Seestar automatically finds, tracks and captures it——revealing more details as they stack.
Three Simple Steps.
Your Journey to the Stars Begins.
2K Dual-Lens. More in View.
Explore distant detail with the telephoto camera and sweeping nightscapes with the wide-angle camera. Capture deep-sky objects and expansive nightscapes with clarity.
Compact Design. Optical Precision.
A folded optical path fits a longer focal length into a compact body, bringing distant celestial details into view.
One-Tap Post-Processing. More Ways to Refine.
Bring out the detail in your astrophotography with one-tap enhancement, or take control with tools for star removal, star reduction, noise reduction, brightness, contrast, saturation, cropping, flipping and more. Get closer to the shot you imagined, every time.
A Wider View. More Ways to Create.
Frame the Milky Way, trace the paths of the stars, and turn a night beneath the sky into a time-lapse.
Freeze the Ground, Two Worlds in Perfect Focus
Intelligently detects and locks the foreground landscape, processing it separately from the sky. Customize the landscape freeze duration. Stars stay sharp during tracking, while the foreground remains clear and natural for crisp, striking nightscapes.
Constellation Recognition
Identify constellation lines and labels with one tap, then use GOTO to lock on quickly. Even beginners can find and recognize constellations with ease.
Star Trails. Time in Motion.
Automatically turn star trail images into dynamic videos. Watch trails extend and converge as the night sky moves through time. One capture becomes a lasting connection with the universe.
Mosaic Stitching
See Beyond a Single Frame.
Some celestial wonders deserve a wider view. Seestar captures overlapping images across your chosen area and stitches them together automatically, bringing more of the night sky into one image.
Equatorial Mode
Compensates for Earth's rotation when tracking celestial targets. Stable tracking supports longer exposures and keeps objects steady in the frame.
Plan Mode
Create an imaging plan and let Seestar follow it through the night. It automatically moves from one target to the next, capturing multiple celestial objects while you sleep.
Remote Control
Your Window to a Darker Sky.
Cloudy skies at home? Connect to a Seestar at a remote location and explore the night sky from wherever you are. Capture images and manage your files—all through the app.
