Celestron f/6.3 Reducer/Corrector

Product Highlights
  • For 5-14" Catadioptric Scopes
  • Widens Field of View
  • Shortens Exposure Times
  • Requires 93633-A Photo Adapter
  • Requires Camera-Specific T-Mount

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.

      No problems with this product. Fitted great on my cpc 9.25. Really useful for viwing nebulae. Thus far used it to photograph M42 and omega centauri, with pretty good results using SLR and despite having cpc on alt-az. Reduces the magnification, giving wider field of view, and allows shorter exposure for astrophotography. T adaptor/slr assembly fits on fine.

      I used this with a Celestron Off Axis Guider and Canon EOS 500D, shots showed a darkened circle around the edges, inner image was fine and good quality (same was shown in the NexImage CCD in the eyepiece turret of the OAG). Have not had an opportunity yet to try this with a different configuration.

          Great product for shortening exposure times shooting through SCT scopes. Use it on a C8 XLT and very pleased with the results.

          Increases the field of view (FOV) when veiwing the large celestial objects (e.g. Moon, Sun, some nebulae, sections of the MilkyWay.) Does vignette when doing imaging.

          Comments about Celestron f/6.3 Reducer/Corrector:

          Never thought something like this could make such a huge difference. Much more sharp, especially the edges. Also increases the field of view. I'm using a canon Mrk III and am still amazed at the improvement.

              I use this with my C6-avx and a Nikon 3100. Cuts my exposure time by a third and provides a flatter field. Optical coatings are great as there is little contrast loss. For astrophotography this is a must have!

                Dears Sirs
                The Celestron focal reducer was delivered in perfect condition, and it worked fine on my telescope.
                Images appear with perfect clarity and without distortion.
                Thank you for your attention.

                  No problems with this product. Fitted great on my cpc 9.25. Really useful for viwing nebulae. Thus far used it to photograph M42 and omega centauri, with pretty good results using SLR and despite having cpc on alt-az. Reduces the magnification, giving wider field of view, and allows shorter exposure for astrophotography. T adaptor/slr assembly fits on fine.
