Live stacking, automatic GoTo and tracking, object database and more!
The ZWO Seestar S50 is packed with smart features that make astrophotography easier AND more impressive. Thanks to live stacking images are automatically combined into one clear, noise-free result. With auto GoTo and tracking The telescope finds and tracks celestial objects independently, while the wireless link and comprehensive star database provide a smooth and intuitive experience.
Read more about these powerful features below and discover how the Seestar S50 can become your all in one observatory for life!
The ZWO Seestar S50 brings the power of a complete observatory setup to a compact and portable size. Lightweight, easy to operate and ready to use within minutes.
The ZWO Seestar S50 is equipped with professional triplet apochromatic optics. These high-quality lenses provide razor-sharp images of the night sky with minimal chromatic aberration. The multilayer anti-reflection coating reduces light loss and delivers a bright, high-contrast image, ideal for both observation and astrophotography with this 50 mm smart refractor
Inside the Seestar S50 is the Sony IMX462 STARVIS sensor, specially developed for low-light performance. Thanks to this sensor, you take sharp and low-noise shots even in dark conditions. The sensor can also capture details in the near infrared (IR) spectrum, adding texture and depth to your images. With a resolution of 1920×1080 pixels, this is an excellent choice for both novice and advanced astrophotographers.
The Seestar S50 uses live stacking, which automatically combines multiple exposures into one bright, detailed image. The longer you expose, the more color and detail become visible, even of objects invisible to the naked eye. With the built-in SkyAtlas, you can easily rotate or zoom the image frame. The telescope then automatically creates a mosaic image of different sections of the sky and merges them into one perfect panorama.
The telescope is completely wireless thanks to the built-in WiFi module. You connect your smartphone or tablet directly to the Seestar, even without a mobile network. Operation is via the intuitive Seestar app, where you can control everything from alignment to shooting and image editing. Bluetooth is only required for initial setup. Before leaving, it is advisable to download the app in advance so that you can use the telescope immediately, whether you are in the garden, camping or under dark skies.
The Seestar S50 is designed for efficient power consumption. With a fully charged battery, you can observe continuously for about 6 hours. During use, you can easily recharge the telescope with a power
Using your smartphone's GPS and internal sensors, the telescope automatically performs alignment and calibration. Thanks to the built-in autofocus, your shots will always stay sharp, both for sky objects and landscape photography. Via Auto GoTo, you simply select an object in the app, and the Seestar looks for it itself and tracks it automatically. The tracking compensates for earth's rotation, so the object remains stable in focus without you having to make adjustments.
In short: The Seestar S50 is a clever telescope that makes astrophotography accessible to everyone. You don't need any experience with alignment or focusing: this telescope does it all by itself. Within minutes it is ready to use, and you can see the nebulae, star clusters and galaxies normally visible only with much larger telescopes.
What you can capture with it
- Nebulae such as Orion and the Veil Nebula
- Galaxies such as Andromeda and Triangulum
- Star clusters such as the Pleiades and the Double Cluster
- The sun with the included solar filter
- Moving objects in time-lapse or tracking mode
The moon and planets are visible, but not the main purpose of this instrument. The Seestar is fully digital, so there is no eyepiece for visual use.
For whom
The Seestar S50 is designed for beginners , experienced astrophotographers and enthusiasts who want instant results without technical settings. Ideal for those who want to start astrophotography such as the moon, deep sky objects and the sun with solar filter, in a simple, reliable way.

Rene van Heemskerk -
I have been using the Seestar S50 for over three weeks now and I must say: this thing has really surprised me. I previously had a traditional telescope, but was always spending hours searching and focusing - that has completely disappeared with this one.
Installation actually went surprisingly smoothly. Everything is neatly packaged and feels solid. Within 15 minutes it was outside ready to use. The accompanying app works intuitively: you pair with the telescope via wifi, and then you get a live image directly on your screen. No more fiddling with eyepieces.
What I especially like is the automatic alignment. You just put the telescope down, press ‘start alignment,’ and within a minute it knows exactly where it is and where to go. Then you can just tap on an object in the app (M42 or Saturn, for example), and the telescope turns toward it. And it's actually on top of it - almost always perfectly centered in the image.
The image quality is impressive, especially for such a compact system. I have now captured several deep-sky objects, including the Andromeda Nebula and the Ring Nebula. With the stacking feature, you can really bring out a lot of detail, even from my fairly light-polluted backyard. You won't see Hubble quality, of course, but for a telescope of this size, it's really impressive.
Only small note: you do need to have some patience. It takes a while for the stacking to really produce results, and if you want to shoot some pictures quickly without long exposures, for example, the results are a little less sharp. But if you take your time and let the telescope do its job, you will get great images in return.
The app also has a ‘live stacking’ feature, where your image slowly builds up as you watch. This really gives a wow factor, especially if you're watching with friends or children - you can literally see the nebulae and stars come to life on your screen.
I now use it mostly on a tripod from the garden, but also took it with me on a weekend trip to the Veluwe. Small and light enough to throw in the car.
All in all: I am immensely satisfied. If you're looking for a smart telescope that allows you to explore the sky right away without hassle, the Seestar S50 is the best choice in this price range as far as I'm concerned, will buy the DWARF 3 as well
