The classic all-rounder that aims itself!
The Bresser Messier 90/900 GoTo adds fully automatic searching and tracking to the classic f/10 all-rounder. The Moon, planets, and the Sun (with the included solar filters) are centered in the field of view at the touch of a button.


Classic f/10 achromatic
The 90mm lens captures approximately 165 times more light than the naked eye. With the 26mm eyepiece, you get 35x magnification; consider around 180x as the maximum. At f/10, chromatic aberration is well under control. Use solar filters only if they are undamaged, and never look at the sun without certified protection.
StarTracker GoTo System
The StarTracker hand controller knows over 100,000 objects and positions the telescope automatically. Servo motors on both axes then track accurately, and you can later connect an autoguider via the ST-4 port. The EXOS-2 GoTo can carry up to 13 kg.
