Orion Optics UK Astrographs

Orion Optics UK astrographs are telescopes designed first for deep-sky imaging, in two families. The AG series are fast Newtonian astrographs, such as the AG8 at f/3.8, from the AG8 to the AG20, used with a Wynne corrector for wide fields. The ODK series are corrected Dall-Kirkham telescopes from the ODK10 to the ODK20Tr, in closed tube and truss versions.

Choose an AG for large nebulae and wide fields, or an ODK for galaxies and small targets at long focal length.
