The Meade f/6.3 Focal Reducer/Field Flattener (4-element, 41mm diameter, multicoated lens elements) # 07545 threads on to the rear cell of any Meade SCT telescope or to other Schmidt-Cassegrain telescope brands. It reduces the telescopes focal ratio by a factor of 0.63. With this accessory, f/10 telescopes are converted to f/6.3 and f/ 6.3 telescopes are converted to f/4.
Simultaneously, it helps to flatten the field, significantly improving edge-of-field corrections. The f/6.3 Meade 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 f/6.3 Focal Reducer duplicates the rear cell thread of the telescope, allowing you to attach all standard rear cell visual and photographic accessories. Has a standard male SCT thread (2" outside diameter x 24 TPI) on one side and a standard SCT female thread on the other.
Product carries full one year Meade factory limited warranty (within US/Canada only).
