Celestron

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.
