Description
This focal reducer and field flattener consists of a four-element multicoated 40mm 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 to the reducer. 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.
A rubber grip ring on the body allows for easy installation of the reducer/corrector on your scope, even when you are wearing gloves.
