Bresser AC 127S/635 - Powerful brightness in compact size
The Bresser AC 127S/635 is made for those who want to see big without a complicated setup. Thanks to its short tube and fast f/5 optics, you'll see bright, wide images of the night sky. Perfect if you want to enjoy the Moon, the Andromeda Nebula or colorful gas clouds - all with striking contrast and clarity.
Big picture, small size
The 127 mm aperture captures a lot of light, allowing you to see even faint deep-sky objects that remain invisible with smaller telescopes. The short construction ensures that the telescope remains stable and hardly vibrates. Thus, your image remains calm even at higher magnifications.
Clear, colorfast display
The four-lens superachromate reduces color aberrations and delivers sharper, more natural images than standard two-lens systems. You'll see bright star fields with clearly separated colors - exactly what you want for visual observation as well as photography.
Solid mount for smooth movement
The EXOS-2 mount is built for precision and stability. Dual bearings keep movements fluid and minimize backlash. With a carrying capacity of 13 kg, everything stays firmly in place, even with additional accessories or cameras. Add an optional motor for automatic tracking - ideal for those looking to take their first steps in astrophotography.
User-friendly and expandable
Bresser's Messier series is designed to grow with you. Start as a beginner, expand later with motors or camera adapters. The sturdy aluminum tube, comfortable handle and stable steel tripod make it durable and easy to handle.
