Bresser EXOS-1/EQ-4 Mount Messier: compact equatorial entry-level
The Bresser EXOS-1/EQ-4 is a compact equatorial mount for small to medium-sized telescopes, with a payload capacity of up to 7 kg (15.4 lb). The worm gear drive with fine adjustments makes manual tracking smooth and precise: it truly helps you get to know the movement of the sky.
The EXOS-1 also has a growth path: with the separate RA motor, the mount tracks automatically, and the separate polar finder makes polar alignment precise. This way, your entry-level mount grows with you without needing replacement.

Load capacity in practice
Zeven kilo betekent: refractors tot zo’n 120 mm en Newtons tot 150 mm opening voelen zich hier thuis. Voor zwaardere buizen is de EXOS-2 de betere basis.
Featured accessories

For whom yes and for whom no
- ✓ Beginners who seriously want to learn how to use an equatorial mount
- ✓ Owners of a light to medium-weight tube
- ✗ Anyone carrying a heavy Newtonian or photo setup: choose the EXOS-2
