Celestron Focal Reducer / Corrector - f/6.3 - 94175

This combination Celestron Focal Reducer/Corrector lens accessory works with all Celestron 5, 8, 9.25, 11 and 14-inch 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, C9.25 and C11 telescopes and f/7 for the C14 telescope.

If offers wide fields of view with any Schmidt-Cassegrain telescope. Used for astrophotography, the Celestron Focal Reducer/Corrector reduces exposure time by a factor of 3.

Celestron does not 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 Celestron Focal Reducer/Corrector. Results are amazing both visually and photographically.
