Celestron Reducer/Corrector f/6.3 This combination focal reducer and field corrector lens accessory works with all Celestron 5 8 9 1/4 11 and 14 Schmidt-Cassegrain 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 C9¼ and C11 telescopes and f/7 for the C14 telescope.

If offers wide fields of view with any Schmidt-Cassegrain telescope. Used for astrophotography it reduces exposure time 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 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.
