The Celestron Focal Reducer is one of the most highly recommended Focal Reducers / Correctors on the market today. The Celestron Focal Reducer is made of top quality glass and it's body and finish are solid. The Celestron f/6.3 Focal Reducer offers wide fields of view with any Schmidt-Cassegrain telescope. Used for astrophotography, the Celestron Focal Reducer reduces exposure time by a factor of 3.
The Celestron Focal Reducer and field corrector lens accessory works with all Celestron 5", 8", 9 1/4", 11" and 14" Schmidt-Cassegrain telescopes. The Celestron Focal Reducer is f/6.3 for the 5", 8", 9 1/4", 11" Celestron SCT Telescopes and f/7.0 for the Celestron 14" SCT Telescope.
The Celestron Focal Reducer makes it possible to have a dual focal ratio telescope without sacrificing image quality.
Celestron doesn't offer an f/6.3 Schmidt-Cassegrain telescope, because the design is impractical, with a large central obstruction, and resulting loss in contrast. This, added to the inability to utilize longer focal ratios for certain objects, led Celestron to design the four-element, fully multicoated f/6.3 Reducer/Corrector results are amazing both visually and photographically.
