Description
Celestron Reducer/Corrector f/6.3
This combination focal reducer and field corrector lens accessory works with all Celestron 5", 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.
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.

I purchased the Celestron reducer/corrector in order to drop the focal length of my older C8 from 2000mm down to 1280mm. The reducer performs as advertised; my low-power eyepieces kept their edge-to-edge sharpness, while increasing the field of view. I'm now able to easily find (with help from a Telrad) and observe those large, faint "fuzzies" at lower power, while still taking full advantage of the light-grabbing power of the 8-inch aperture. I could not notice any change in optical performance, except for the reduced focal length and increased field of view for a given eyepiece. If you're looking for nice, wide, low-power views out of your SCT, but don't have the $700.00 for a TV 50mm panoptic (I didn't!), this is definitely the way to go! For a 2000mm FL SCT, adding the reducer/corrector will make a 32mm plossl act like a 50mm (40X mag), increasing the field of view, and saving you hundreds of dollars. Well worth the cost!

I'm using this on my Celestron C6-A optical tube and this is really a good focal length!

Comments about Celestron f/6.3 Focal Reducer / Corrector Lens:
This focal reducer definitely opens up the view a lot. I leave it on all the time except when viewing planets or the moon. You will be amazed at how much more you can see in some star fields once the field of view is widened. It has an impressively strong construction and threads easily to the back of my 8SE. It does not degrade the view at all and really makes looking at deep space objects more enjoyable. It makes it almost as if you have two different scopes. Handle with care, though. Definitely recommend.

Comments about Celestron f/6.3 Focal Reducer / Corrector Lens:
A remarkable astroviewing accessory. It converts a narrow, F10-speed SCT to a wide, rich-field telescope in one easy step, and can readily be removed to change your telescope back to its previous narrow-field view.

Comments about Celestron f/6.3 Focal Reducer / Corrector Lens:
This focual reducer does what it is supposed to do. However on my Nextstar 8SE, with the reducer in place, I cannot get my Nikon D300 to focus. There are ways to get around this I have been told, but I am in the midst of finding the best way.
