Telescopes General Series ODK

Highend Astrographs with Carbon tubes

The ODK-Series (Optimised Dall-Kirkhams) is based on a focal ratio of f/6.8, fast enough for some superb deep sky photo-visual use and, still have enough focal length for high resolution planetary work both visual and CCD applications.
The tube is constructed from Carbon Fibre sandwich design. Very, very strong to avoid flexing and, zero expansion to ensure the focal plane does not change over long photographic exposures. Being an open tube design and very short, cool down times are remarkably fast.
