This combination focal reducer and field corrector lens accessory works with all Celestron C5, C8, C9.25", C11 and C14 telescopes.  This clever accessory makes it possible to have a dual focal ratio instrument without sacrificing image quality.  The Reducer/Corrector is f/6.3 for C5, C8, C9.25" and C11 telescopes and f/7.0 for the C14 telescope.

It offers wide fields of view with any Schmidt-Cassegrain telescope.  Used for astrophotography, it reduces exposure times by a factor of 3.

Celestron doesn't offer a f/6.3 Schmidt-Cassegrain telescope, because the design is impractical-with a large central obstruction and a resulting loss in contrast.

    Comments about Celestron f/6.3 Reducer/Corrector:

    I used this with a Celestron Off Axis Guider and Canon EOS 500D, shots showed a darkened circle around the edges, inner image was fine and good quality (same was shown in the NexImage CCD in the eyepiece turret of the OAG). Have not had an opportunity yet to try this with a different configuration.
