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, 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.

"This focal reducer does what it is described to do. Its a beautiful addition to any catadioptric telescope. Take great care when handling it,though, because there is no protection for it once out of its box. I would like to see more durable lens covers, too. They are somewhat thin and flimsy.

Very Useful accessory!

Pros
- None
Cons
- Astronomy
Best Uses
"The reducer/corrector sure makes the SCT a much more versatile instrument. I leave mine on the scope all the time. It gives you much wider fields of view with the same eyepieces and is cheaper than buying new low power eyepieces. Highly recommended. "

Pros

Best Uses
"Used to decrease the focal length from 10 to 6.3 on a 9.25 Celestron CAT.
Decreased focal length = increased light gathering power and wider field of view.
