For sale is my Celestron f/6.3 Focal Reducer. For Astrophotography. Will turn your scope into a wide field scope. Bought it from the U.S.A. only to find out that the scope I got was not compatible. I use a Celestron 800 HD EDGE. This will work for all Schmidt Cassegrain scopes of any brand except for Celestron HD EDGE scopes.
Price Php5,000 FIXED.
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.
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.
