Bresser Telescope AC 102/600 AR-102S Messier Hexafoc EXOS-2 GoTo (54275)

The traditional company Bresser offers telescopes under the Messier brand, providing an excellent price-performance ratio for ambitious beginners. These Messier telescope systems are expandable and retrofittable, making them suitable for use well beyond the initial entry point.

Bresser Messier AR-102S
The Messier AR-102S is an excellent choice for ambitious beginners looking to explore objects beyond our solar system. With this telescope, you can observe structures in the Orion Nebula at an incredible distance of 1,500 light-years (14,200,000,000 km). It also allows you to view the craters on the Moon, the rings of Saturn, and Jupiter’s Great Red Spot.

Bresser EXOS-2 Mounting
The EXOS-2 is a robust mounting system with a high load capacity (up to 13 kg for visual use and 10 kg for astrophotography). It provides precise tracking for both visual observations and astrophotography. Double radial ball bearings ensure smooth operation, while optimized RA axes reduce play. This sturdy and precisely crafted mount makes it easy to begin astrophotography. Additionally, a motorized 2-axis control can be added.

Included with the EXOS-2 Mount:

• Sturdy mounting

• Matching counterweight

• Robust steel tripod with three legs

GoTo System for EXOS-2
The GoTo system simplifies celestial observations, even for beginners. By pressing a button, the telescope automatically moves to your selected celestial object (planet, nebula, or galaxy) and tracks it continuously. The database contains over 100,000 objects, allowing you to observe or photograph faint objects without needing advanced location skills.
