Ambitious beginners and advanced observers alike will see the brightest objects outside our solar system with the MESSIER AR-102xs. Watch details in the Great Orion Nebula from the astonishing distance of 1500 lightyears (14.200.000.000.000 km)! Scanning the lunar terminator is simply a pleasure. Scanning the Milky Way in Saggitarius shows a multitude of deep-sky objects.
Richfield telescope with ED glass lens and a short focal length of 460mm. Suitable for traveling and to observe large open star clusterns and the milky way
Mount and Tripod. The BRESSER Messier beginners series of telescopes. Within this series you find smaller optics mounted stable on the new BRESSER EXOS 2 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 2 with a robust stainless steel tripod bears optical tubes weighing up to 13kg stable for visual observation. The optional motor drive for the RA+DEC 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.
