- Works with all Celestron 5", 6", 8", 9 1/4", 11" and 14" Schmidt-Cassegrain telescopes
- The Reducer/Corrector is f/6.3 for C5, C6, C8, C9¼ and C11 telescopes and f/7 for the C14 telescope
- Can be used visually and for astroimaging
The Celestron f/6.3 focal reducer and field corrector accessory works with all Celestron 5", 6", 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 will give f/6.3 for Celestron's C5, C6, C8, C9¼ and C11 SCT telescopes and f/7 for the C14 SCT telescope. From a visual perspective, its used offers wide fields of view with any Schmidt-Cassegrain telescope. When used for astrophotography, it will also give a wider field of view and its use also 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 utilise longer focal ratios for certain objects, led Celestron to design the four-element, fully multi-coated f/6.3 Reducer/Corrector. Results are amazing both visually and photographically.
