BRESSER Messier AR-90L/1200 Optical Tube assembly (Refurbished)

With teleextenders it is possible to extend the effective focal length of a telescope system, resulting in higher magnification for the observation of the moon, the planets or small Deep-Sky objects with the same eyepieces. So you can use the advantages of eyepieces with longer focal length - such as the bigger eye distance and the more relaxed observing comfort - at high magnifications also.These teleextenders incorporate a telecentric optical design that deliveres a excellent image sharpness over the whole field of view and are premium choices for visual observations and astrophotography. The combination of excellent fully multicoating with superior optical design makes the Focal Extenders superior to classic Barlow lenses.FEATURESSuitable for visual observations and astrophotographyTriples the effective total focal length of the telescopeFour lens telecentric designFully multicoatedFilter thread for color or nebula filtersSCOPE OF DELIVERY Fokal Extender 3 x Adapter 2" (50,8mm) auf 1,25" (31,7mm)

NEW - now including a high-quality aperture Solar-filter for safe observation of sunspots, eclipses and planet transits. Great telescope for night and solar observation.Ambitious beginners and advanced observers alike will see the finest details of our Moon and Planets with the BRESSER Messier AR-90L telescope. Watch details on Mars like the white polar ice-cap, the Cassini division on the ring of Saturn or the great-red-spot on Jupiter. Scanning the lunar terminator is simply a pleasure. 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 2 with a robust 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.
