The Bresser Messier AR-90 telescope is an excellent instrument for beginners astronomy. The 90 mm lens collects 200 times more light than the unarmed eye, thus ensuring large observation possibilities.
The short focal length makes the telescope provide a wide field of view and is ideal for observing large clusters and dairy pathways. This well-known refractor can also be used when observing the moon and planets. It will also reveal the beauty of the deep sky objects. It is impossible to forget the view of the Great Nebula in Orion or the galaxy M31, using this refractor.
The AR-90 refractor gives images many times brighter than the Galileo instrument, which he used during his observations over 400 years ago.
The universal telescope dovetail allows the instrument to be mounted on typical telescopic assemblies. Dovetail is equipped with a hole with photo thread (1/4 ") allowing also to place the telescope on photographic tripods.The small size ensure ease of carrying and transport.It is also an excellent instrument for ground-based observation, much cheaper than dedicated for this purpose observation telescopes.
The modernized version of the telescope, in addition to visual changes, includes a number of structural changes. As a result, the telescope has a modern, timeless appearance and a number of important features that improve the performance. Optical system
