You will never give the Bresser Messier AR-90L Telescope away voLuntarily.

Because of the extra long focal length ratio F/13.2 this telescope offers incredible sharpness and contrast but extremly low color-aberration.

Mount and Tripod. The Bresser Messier beginners series of telescopes. Within this series you find smaller optics mounted stable on the new Bresser EXOS 1 mount. This combination means more value for money and puts an end to flimsy beginners scopes which discourage most of the beginners due to small, under engineered mounts. The EXOS 1 with a robust steel tripod bears optical tubes weighing up to 7kg stable for visual observation. The optional motor drive for the RA axis makes usage even more comfortable, so there is no need of manual tracking and the object is kept steadily in the field of view.
