Bresser Maksutov telescope MC 152/1900 Messier Hexafoc EXOS-2 (54354)

The Messier series by Bresser provides telescopes that deliver excellent performance at an affordable price, making them ideal for ambitious beginners. These telescopes are designed to be expandable and retrofittable, ensuring they remain useful as users progress in their astronomy journey.

Maksutov Telescopes
Maksutov telescopes are compact and portable, making them perfect for travel or on-the-go observations. Their enclosed optics and collimation stability ensure durability and robustness.

Despite their compact design, Maksutov telescopes feature a long focal length. However, their field of view is narrower compared to achromatic refractors, making them ideal instruments for observing the Moon and planets. When equipped with an Amici prism, they are also excellent for nature observation and photography.

This telescope is now equipped with the improved Hexafoc focuser, which has a free aperture of 65 mm. For astrophotography, it can be upgraded with a 1:10 reduction ratio fine focuser (available as an accessory) for precise focus adjustments.

Bresser EXOS-2 Mount
The EXOS-2 is a robust equatorial mount designed for both visual observations and astrophotography. It has a high load capacity of up to 13 kg for visual use and 10 kg for photographic use. The mount ensures precise tracking, supported by double radial ball bearings for smooth operation and an optimized RA-axis that minimizes play.

This durable and precisely engineered mount is ideal for beginners entering astrophotography. Additionally, a motorized two-axis control system can be added as an optional upgrade.

Included with the Mount:

• Sturdy equatorial mount

• Counterweight included (4.5 kg)

• Robust steel tripod with three legs
