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.

Due to the short focal length this telescope provides large and bright fields of view. Don't forget to observe the Anrdomeda Galaxy with the BRESSER Messier AR-127S! The glow of this object that you can observe from the immense distance of 2 million lightyears is as spectacular as it is to watch large nebulae with the Messier AR-127S. Because of the large aperture it is even possible to use nebular filters on the Messer AR-127S. These filters can enhance the appearance of emission nebulae to en astonishing contrast level. The special four lens construction delivers a better perfomance than a classical two lens achromat of this focal length.The short tube and the rigid mount also make this combination ideal for short easy viewing sessions, especially if the telescope has to be moved for observation
