Bresser Telescope AC 102/460 AR-102 Messier Hexafoc EXOS-2 (59992)

The Bresser Messier series offers telescopes designed for ambitious beginners, providing excellent performance at an affordable price. These telescopes are expandable and retrofittable, ensuring they remain useful as users progress in their astronomy journey.

The AC 102/460 refractor telescope is compact and features a short focal length, making it ideal for wide-field observations. It is perfect for viewing large structures in the night sky, such as open star clusters along the Milky Way.

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