The reducer/corrector duplicates the rear cell thread of the telescope, allowing you to attach all standard rear cell visual and photographic accessories. It reduces the telescope’s focal ratio by a factor of 0.63. An f/10 telescope is converted to an f/6.3, while an older Meade f/6.3 telescope is converted to an f/4. Simultaneously, the 41mm-diameter lens system helps to flatten the field, significantly improving edge-of-field corrections. The f/6.3 focal reducer enables a reduction of photographic exposure times by about 50%, while producing an actual field diameter of 1.5" at the film plane.

The reducer/corrector comes 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.
