Seestar S30 Review
Wondering how the Seestar S30 works, how to use it, and how it compares to other smart telescopes? In this review, Agena Astro affiliate AstroBackyard shares everything you need to know about the S30:
Three Versatile Shooting Modes
Stargazing Mode
Astrophotography has never been easier! Capture stunning images of galaxies, nebulae, star clusters, and more. Simply open the mode or sky atlas, select an object, and use the “go-to” function to center it. The S30 then stacks images in real time, revealing details normally hidden from the naked eye.
Scenery Mode & AI Tracking
Scenery Mode is for photographing terrestrial objects like landscapes, cityscapes, and wildlife. Simply select the mode in the app and frame your shot using the dual-lens system. With AI tracking, the S30 automatically follows moving objects.
Solar System Mode
Capture the Sun with the included magnetic solar filter and record surface details, including sunspots. Use the app to take photos, videos, or solar time-lapses, and the RAW video option lets you create stackable files for sharper results. The Moon is just as easy. Skip the solar filter and follow the same steps to capture craters, maria, and other surface details in stunning clarity.
Note: The Seestar isn't equipped for planetary photography.
Intuitive Seestar Companion App
The free Seestar app is your portal to the stars! Simply download it from the Apple App Store or Google Play Store and connect to any Seestar smart telescope to get started. In the app, you'll find useful features like:
- A Sky Atlas with over 4,000 objects to choose from.
- A suggested list of best celestial objects tonight.
- Multiple image capture modes such as live stacking, time lapse, and video.
- A global social community of other Seestar users where you can share your images.
- Plus much more!
Seestar Supports Equatorial Mode
Using the dedicated Seestar TH10 mount, or any compatible tripod and wedge, you can easily enable Equatorial Mode through the app. This mode provides stable tracking, longer exposure times, and reduced field rotation, letting you capture sharper, more detailed astrophotography images like a pro.
Dual Lens Design
The S30 features two lenses: one telephoto lens and one wide-angle lens. The telephoto lens is used for taking close-up shots of astronomical and distant objects, while the wide-angle lens lets you capture landscapes and nightscapes.
Tip: Use the wide-angle lens to find your objects before zooming in.
Enhance Your Views with 4 Included Filters
The S30 comes with four filters, three built-in and one external solar filter, designed to make capturing stunning images easier no matter your location. Filters enhance contrast, reduce unwanted light, and bring out fine details that might otherwise be lost, especially under light-polluted skies.
- Light Pollution Filter lets only light from nebulae pass through while cutting city and suburban glow, making deep-sky astrophotography possible anywhere.
- UV/IR Cut Filter is perfect for galaxies and star clusters, producing sharper and more accurate colors.
- Dark Frame Filter removes noise automatically, giving cleaner and more professional-looking images.
- Solar Filter allows safe solar photography while revealing surface details such as sunspots.
Using these filters makes a huge difference, ensuring clearer, brighter, and more vibrant results every time.
Go Extra Wide with Mosaic Mode
Mosaic Mode lets you take bigger pictures of the night sky by automatically stitching multiple images together. Once you’ve located an object in the app’s sky atlas, start a mosaic session by selecting “framing” from the options on the right. You can zoom between 1x and 2x, rotate the frame, and when your setup is ready, press “go-to”, the S30 handles the rest. This makes it easy to capture large nebulae, star clusters, or other deep-sky objects in one wide shot.
AI Noise Reduction & Imaging Editing
The ZWO S30 utilizes the power of AI to reduce noise in your astrophotography images, resulting in a much cleaner final image. The Seestar app also includes a photo editor with brightness, contrast, saturation, and denoising controls. With Deep Sky Restack, you can review and stack only the best frames in real time or after your session. Plus, all your data can be downloaded for advanced editing in programs like Photoshop or PixInsight.
3 Different Photo Modes
The S30 features three different photo modes: photo, time lapse, and video recording so you can get the best shot possible, whether it be of the night sky or terrestrial objects!
Seamless Sharing to Social Media
When you're ready to share your photos, you can simply save them to your smart device and post away. Also included in the Seestar app is a social network for sharing and staying up to date with the latest images from other Seestar telescope owners in the community.
Up to 6 Hours of Battery Life
The S30's internal lithium 6000Ah battery can last up to 6 hours on one charge (4 hours when using video mode). You can also connect a portable battery to the S30 with the included USB-C cable for even more battery life.

Seestar S30 Review
Wondering how the Seestar S30 works, how to use it, and how it compares to other smart telescopes? In this review, Agena Astro affiliate AstroBackyard shares everything you need to know about the S30:
Three Versatile Shooting Modes
Stargazing Mode
Astrophotography has never been easier! Capture stunning images of galaxies, nebulae, star clusters, and more. Simply open the mode or sky atlas, select an object, and use the “go-to” function to center it. The S30 then stacks images in real time, revealing details normally hidden from the naked eye.
Scenery Mode & AI Tracking
Scenery Mode is for photographing terrestrial objects like landscapes, cityscapes, and wildlife. Simply select the mode in the app and frame your shot using the dual-lens system. With AI tracking, the S30 automatically follows moving objects.
Solar System Mode
Capture the Sun with the included magnetic solar filter and record surface details, including sunspots. Use the app to take photos, videos, or solar time-lapses, and the RAW video option lets you create stackable files for sharper results. The Moon is just as easy. Skip the solar filter and follow the same steps to capture craters, maria, and other surface details in stunning clarity.
Note: The Seestar isn't equipped for planetary photography.
Intuitive Seestar Companion App
The free Seestar app is your portal to the stars! Simply download it from the Apple App Store or Google Play Store and connect to any Seestar smart telescope to get started. In the app, you'll find useful features like:
- A Sky Atlas with over 4,000 objects to choose from.
- A suggested list of best celestial objects tonight.
- Multiple image capture modes such as live stacking, time lapse, and video.
- A global social community of other Seestar users where you can share your images.
- Plus much more!
Seestar Supports Equatorial Mode
Using the dedicated Seestar TH10 mount, or any compatible tripod and wedge, you can easily enable Equatorial Mode through the app. This mode provides stable tracking, longer exposure times, and reduced field rotation, letting you capture sharper, more detailed astrophotography images like a pro.
Dual Lens Design
The S30 features two lenses: one telephoto lens and one wide-angle lens. The telephoto lens is used for taking close-up shots of astronomical and distant objects, while the wide-angle lens lets you capture landscapes and nightscapes.
Tip: Use the wide-angle lens to find your objects before zooming in.
Enhance Your Views with 4 Included Filters
The S30 comes with four filters, three built-in and one external solar filter, designed to make capturing stunning images easier no matter your location. Filters enhance contrast, reduce unwanted light, and bring out fine details that might otherwise be lost, especially under light-polluted skies.
- Light Pollution Filter lets only light from nebulae pass through while cutting city and suburban glow, making deep-sky astrophotography possible anywhere.
- UV/IR Cut Filter is perfect for galaxies and star clusters, producing sharper and more accurate colors.
- Dark Frame Filter removes noise automatically, giving cleaner and more professional-looking images.
- Solar Filter allows safe solar photography while revealing surface details such as sunspots.
Using these filters makes a huge difference, ensuring clearer, brighter, and more vibrant results every time.
Go Extra Wide with Mosaic Mode
Mosaic Mode lets you take bigger pictures of the night sky by automatically stitching multiple images together. Once you’ve located an object in the app’s sky atlas, start a mosaic session by selecting “framing” from the options on the right. You can zoom between 1x and 2x, rotate the frame, and when your setup is ready, press “go-to”, the S30 handles the rest. This makes it easy to capture large nebulae, star clusters, or other deep-sky objects in one wide shot.
AI Noise Reduction & Imaging Editing
The ZWO S30 utilizes the power of AI to reduce noise in your astrophotography images, resulting in a much cleaner final image. The Seestar app also includes a photo editor with brightness, contrast, saturation, and denoising controls. With Deep Sky Restack, you can review and stack only the best frames in real time or after your session. Plus, all your data can be downloaded for advanced editing in programs like Photoshop or PixInsight.
3 Different Photo Modes
The S30 features three different photo modes: photo, time lapse, and video recording so you can get the best shot possible, whether it be of the night sky or terrestrial objects!
Seamless Sharing to Social Media
When you're ready to share your photos, you can simply save them to your smart device and post away. Also included in the Seestar app is a social network for sharing and staying up to date with the latest images from other Seestar telescope owners in the community.
Up to 6 Hours of Battery Life
The S30's internal lithium 6000Ah battery can last up to 6 hours on one charge (4 hours when using video mode). You can also connect a portable battery to the S30 with the included USB-C cable for even more battery life.
