OVERVIEW

This combination focal reducer and field corrector lens 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 is f/6.3 for C5, C6, C8, C9¼ and C11 telescopes and f/7 for the C14 telescope.

DESCRIPTION

REDUCER/CORRECTOR F/6.3

If offers wide fields of view with any Schmidt-Cassegrain telescope. Used for astrophotography, it 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 utilize longer focal ratios for certain objects, led Celestron to design the four-element, fully multicoated f/6.3 Reducer/Corrector. Results are amazing both visually and photographically.

THE #94175 REDUCER/CORRECTOR LENS IS NOT COMPATIBLE WITH CELESTRON EDGEHD OPTICAL SYSTEMS.

Avery L. ★★★★★

My stars are much sharper across the entire field now, especially at the edges, which used to be a real problem with my 8" SCT. It threaded on easily and cut my exposure times in half, exactly what I needed for deep-sky imaging.

Penelope ★★★★★

I’ve been using this reducer-corrector on my 11" scope, and the reduction to f/6.3 really speeds up exposures while keeping stars sharp across the whole frame. The threads mate perfectly with my SCT, and it’s dramatically improved my wide-field deep-sky shots.

Joshua Z. ★★★★★

My stars are noticeably sharper across the whole frame now, and it shaved about 20 minutes off my total exposure time for a single target. Perfect fit on my 8" SCT without any wobble.
