Celestron Reducer / Corrector f/6.3

Little giant!Celestron's combination focal reducer and field-corrector lens accessory is a little wonder. It makes it possible to have a dual-focal-ratio instrument without sacrificing image quality and it works with all Celestron C5 C8 C9.25 C11 and C14 telescopes yielding f/6.3 for C5 C8 C9¼ and C11 telescopes and f/7 for the C14.Wide field of viewThe Celestron Reducer/Corrector f/6.3 offers wide fields of view with any Schmidt-Cassegrain telescope. And when used for astrophotography it reduces exposure time by a factor of 3.Spectacular resultsCelestron doesn't manufacture an f/6.3 Schmidt-Cassegrain telescope because the design would have to incorporate a large central obstruction producing marked loss in contrast. In addition it would be unable to utilize longer focal ratios for certain objects. So Celestron designed the four-element fully multicoated f/6.3 Reducer/Corrector. It's a clever and highly functional accessory. Both visually and photographically its images will amaze you.Navigate the night sky with Celestron Sky Maps.
