Smart Telescope for Everyone: Easy Access to the Night Sky Reach for the stars with the ZWO Seestar S50 Smart Telescope. This innovative, smart apochromat combines high-quality optics and smart technology with incredible ease of use! Imagine sitting relaxed on your terrace, a glass of wine in hand, while the Seestar S50 explores the vast expanses of the universe for you and sends real-time images to your smartphone or tablet. Astronomy from the Comfort of Your Couch Simply choose your desired object from the countless galaxies and nebulae available in the star catalog of the intuitive app. The ZWO Seestar S50 Smart Telescope will automatically move to the selected object. The all-rounder automatically focuses on the celestial object before beginning the capture and sends real-time images to your smartphone or tablet. The smart telescope independently sets the optimal camera settings such as exposure time, ISO value, or aperture. High-Quality Optics Meets Smart Technology The high-quality apochromat refractor optics of the Seestar S50 ensure exceptionally clear and color-accurate images. The combination of top-notch optics, advanced automatic star recognition, and effective GoTo functionality makes this smart telescope a powerful instrument for night observation and astrophotography – accessible to everyone! The integrated camera supports high resolutions that capture even the finest details in distant galaxies and nebulae. Focus on the Essentials The Seestar S50 features an integrated filter change mechanism that can be controlled via the app. By default, the UV/IR-CUT filter is used, eliminating unwanted infrared and ultraviolet light while allowing the crucial H-alpha emission nebula band for astronomical photography to pass through. This results in more contrast-rich images of many deep-sky objects. Automatic Image Stacking for Razor-Sharp Shots The Seestar S50 uses the stacking method for creating astrophotos. Multiple individual images are combined or "stacked" in real-time to form a new image. The final image becomes sharper and more detailed as more individual images are combined. Experience how a galaxy millions of light-years away takes shape before your eyes, revealing more details with each passing minute. The result is exceptionally clear images that reveal the depths of space with impressive detail. For Stacking Pros Too Already familiar with stacking and prefer to do the image processing yourself? No problem – the Seestar saves each individual image in RAW format in its internal storage on request. Also a Master of Observation During the Day Not only stars and galaxies at night, but the Seestar S50 also offers fascinating observation possibilities during the day. Create landscape images and safely observe the sun with the included solar filter, marveling at its impressive sunspots. The S50 is a true all-rounder for any time of day or night. Share Your Discoveries The Seestar S50 makes it easy to quickly and easily share your astrophotographic achievements with friends or the astronomy community. With just a few clicks, you can publish your images directly from the app on social networks. Whether capturing fascinating lunar craters, glowing nebulae, or colorful galaxies – share your observations and inspire others with your discoveries!

This reflecting telescope shows not only the big planets, but also bright deep-sky objects when you are observing under dark skies. Fully equipped, and with a mount that is easy to use, this telescope is ideal for a beginner that has no astronomical knowledge, but wants to immerse him or herself in space. Explore the moons and cloud bands of Jupiter or the majestic rings of Saturn, or find other galaxies, star clusters and nebula on a moonless night. Please note: Reflector telescopes with optical design “Newton” are very good for astronomical observing at the starry night sky. But these telescopes are not well usable for observing landscape and nature during daylight. Therefore we suggest refractor (lens) telescopes for landscape and nature observing.
