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.

    f/6.3 Reducer/Corrector is rated 4.7 out of 5 by 35.
    Rated 5 out of 5 by from A Must Have With any SC OTA you are going to have a limited FOV. The Celestron f/6.3 Reducer/Corrector takes care of that and improves photon capturing. Easy to use, it never leaves my OTA also keeping dust and debris out. Images are clear and crisp near to the very edge of the expanded view plane.

    Rated 5 out of 5 by from Reducer 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.

    Rated 5 out of 5 by from Glad I got it. I see a big difference in the brightness of the moon and stars. I wished I had purchased this long ago. It will remain on my telescope probably with all of my viewing and astrophotography. I have it on my Nexstar 6SE.

    Rated 5 out of 5 by from Well made and does its job 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!

    Rated 5 out of 5 by from A must have for your Celestron SCT I use this reducer on my Celestron 14 SCT and works great. Great accessory for deep view. Works with all my eyepieces and can focus with my Nikon D800 with a T-adpater.

    Rated 5 out of 5 by from WOW! 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.

    Rated 5 out of 5 by from best accessory I have Great for Lunar if your FOV is restricted on your current scope. Also great for long exposure as it bring your F10 down to an F6.3
