Bresser AC 102S/600 - Compact, bright and ready to explore the sky
The Bresser AC 102S/600 is made for anyone who wants to experience the night sky in a new way. With its 102 mm aperture, it captures a lot of light, giving you bright and high-contrast images of the Moon, Jupiter, Saturn and even nebulae and star clusters. The short focal length of 600 mm provides a wide field of view - ideal for wandering the Milky Way or tracking comets.

Wide image, clear result
You can see the Moon in razor sharp focus, including craters and shadows. Planets show color differences and cloud bands, while open clusters sparkle like diamonds. The telescope smoothly magnifies up to 200× without losing clarity, so every detail remains visible.
Perfect for comets and deep-sky
The bright f/5.9 optics allow you to see not only the bright planets, but also nebulae and comets. The wide viewing angle makes it easy to see large objects in one image - an experience not offered by many larger telescopes.
Precise focusing with Hexafoc
The robust Hexafoc Focuser with a clear aperture of 64 mm lets you focus effortlessly. For those who want extra precision, there is an optional 1:10 micro fine adjustment, so you can focus razor sharp even at high magnifications.
Stable with the EXOS-2 mount
The sturdy EXOS-2 mount keeps the telescope perfectly balanced. You can track smoothly without vibration, which is especially important at higher magnifications. Want to take astrophotography further? With motor control, tracking becomes automatic and extremely precise.
Ready to use out of the box
The Bresser AC 102S/600 comes complete with a 26 mm eyepiece, 6×30 viewfinder, 2″ to 1.25″ adapter and a stable steel tripod. Within minutes you'll be outside, ready to explore the sky.
