Description
This combination focal reducer and field flattener consists of a four-element multicoated 41mm lens in a metal cell. It threads onto the rear cell of 5″ to 16″ Celestron and Meade Schmidt-Cassegrain telescopes, making it possible to have a dual focal ratio instrument without sacrificing image quality. The reducer/corrector duplicates the rear cell thread of the telescope, allowing you to attach all standard rear cell visual and photographic accessories. The reducer/corrector converts the f/10 focal ratio of Celestron C5, C8, C9, and C11 telescopes (and all Meade 8″ and larger f/10 telescopes) to f/6.3. The f/11 C14 telescope becomes an f/7. When used for astrophotography, it reduces exposure times by a factor of 3, with an actual field diameter of 1.5″ at the film plane.
The reducer/corrector is supplied with full instructions and with plastic dust caps for both sides of the lens assembly. A rubber grip ring on the body allows for easy installation of the reducer on your scope, even when you are wearing gloves.
