Celestron - Reducer / Corrector f/6.3

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, C9.25 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.
