Celestron f/6.3 Focal Reducer / Field Flattener

Photo visual reducer / corrector F / 6.3 - for SC (non Edge HD) This photo visual corrector / reducer is compatible with all Schmidt-Cassegrain Celestron telescopes (non Edge HD) 5 ", 6", 8 ", 9 1/4 ", 11" and 14 ". This optical accessory offers the possibility of using your instrument with two opening ratios: original F / 10 and F / 6.3 for the Celestron range set out above and F / 7 for the C14. This accessory is made up of 4 anti-reflective lenses for all surfaces to maintain very good image quality. Used in astrophotography, it reduces the exposure time by a factor of 3. The applications for visual and photographic observations are numerous.
