Descrizione prodotto:

Purtroppo, questa descrizione non è stato tradotto in italiano, in modo da trovare a questo punto una descrizione inglese.

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.

To assist cool down of the telescope, each model is fitted with three fans, all positioned behind the primary mirror.

Exact focusing across the ODK range is achieved with the ACU-3S 3”-Crayford Focuser featuring a 10:1 reduction drive.

Good images need good optics, all fitted in reliable, stable and precise engineering.
