Omegon Ritchey-Chretien Pro RC 154/1370 OTA

The Omegon Ritchey-Chretien Pro Telescope 154/1370 is a Ritchey-Chrétien photographic telescope with a 154mm main mirror and a 1370mm focal length. Omegon’s Ritchey-Chrétien telescopes have a flat field of view, with no coma or color defects at all, and are therefore particularly well-suited for astro photography. A long focal length is good for describing galaxies, for example. The mirrors with a low coefficient of thermal expansion of the telescope are 92-94% reflective BK7 quality.

The telescope comes with a 2 "two-speed Crayford focusing device. The main mirror is permanently mounted, so there is no" mirror flop "familiar from other Cassegrain telescopes when focusing. Three extensions of the focusing device are included to find the right back focus.

NOTE! Just a telescope. Viewfinder tube, eyepiece and angle mirror are not included.
