The Celestron focal reducer /*C*and*C*/ field corrector lens accessory works with all Celestron C5, C8, C9-1/4, C11 /*C*and*C*/ C14 SCT telescopes. This clever accessory makes it possible to have a dual focal ratio instrument, without sacrificing image quality. The Celestron reducer/corrector is f/6.3 for C5, C8, C9 /*C*and*C*/ C11 telescopes /*C*and*C*/ f/7 for the C14 telescope. The Celestron 6.3 focal reducer is /*C*not*C*/ compatible with either the Celestron HD /*C*and*C*/ Meade ACF scopes /*C*and*C*/ OTA

The Celestron focal reducer /*C*and*C*/ field corrector offers wide fields of view with any Schmidt-Cassegrain telescope. Used for astrophotography, it reduces exposure time by a factor of 3. The Celestron focal reducer uses fully multicoated optics for the best image quality /*C*and*C*/ light transmission.
