Orion Optics UK Telescopes

Orion Optics UK telescopes are optical tube assemblies from a British maker of Newtonian and Cassegrain optics. The collection covers VX and IDEAL Newtonians from 6" to 16" with long focal length L versions, CT carbon fibre Newtonians, AG Newtonian astrographs up to the AG20, and ODK corrected Dall-Kirkham astrographs in closed tube and truss designs.

Tubes are sold without mounts, so you can pair them with your own equatorial mount, a Dobsonian base or an observatory pier.
