Omegon 90/500 OTA Telescope

Omegon 90mm Guidescope: the travel and guide scope in one

The Omegon 90mm Telescope is ideal for panoramic viewing or guiding faint stars. Where small guide scopes fail, where there simply isn't a brighter star in sight, that's where Omegon's 90mm refractor really shines. But there is more to this telescope...

For nature and sky: Achromatic with 90mm aperture

With a focal length of just 500mm, this achromatic lens telescope is extremely compact. Therefore, use it not only as a guide telescope, but also on vacation or as a travel telescope for wide-field observation. Reflections are reduced by an internal aperture system and multi-coating on the lens doublet. Observe with a 2" eyepiece at low magnification and experience a fantastic impression of the sky and nature. You can also go into detail with the telescope up to a useful 80x magnification.
