Bresser Messier AR-127S / 635 EXOS-2 / EQ5 Hexafoc

The telescope consists of a telescope (refractor) and an equatorial mount including a tripod. The optics have a free opening of 127mm with a focal length of 635mm and thus an opening ratio of F5. The refractor has many extras, such as pipe clamps with handle and integrated camera, 31.7mm (1.25 ") zenith mirror or 8x50 viewfinder, and an equatorial (also parallactic) EXOS-2 mounting (Only the left / right and top / bottom axes) (azimuthal mount). With the included 8x50 viewfinder, the sky objects can be easily found. The viewfinder also has a crosshair to allow for a more comfortable viewing in the dark.The mount has an illuminated pole searcher which makes the north orientation extremely easy to navigate and allows the objects to be adjusted precisely in the eyepiece by means of two flexible shafts connected to the mechanical feint drive The sturdy tubular steel tripod is steplessly height-adjustable and thus guarantees a comfortable observer position.

Application area: The Bresser Messier AR-127 on EXOS-2 offers the ambitious amateur astronomer a good look with a stable universal mount. 127mm telescopic opening and the narrow focal length are perfect for large-area objects such as open star clusters and large-area fog. For detailed observations on the moon and for the planets of our solar system, it is advisable to obtain additional eyepieces and / or a barlow lens to increase the focal length. With a total weight of approximately 24 kilos composed of the three parts (tube, mount with counterweight, tripod), the telescope is still suitable for missions outside the bright cities. Only then the optics can bring the full performance.

Special features: Bresser EXOS-2 Mount The equatorial (parallactic) mount with a load capacity of up to 13 kilograms (depending on the length of the telescope) and a polish searcher. Ball bearings in both axles ensure precise, easy running. An optional GoTo motor set can be used to facilitate tracking and navigation during observation.
