The Meade f/6.3 Focal Reducer/Field Flattener for Meade Schmidt-Cassegrain models, improves edge-of-field correction and reduces exposure times by close to 50%. The Meade f-6.3 Focal Reducer may be used to increase field
of view and reduce magnification for visual applications. An important advancement in high-resolution focal reduction systems, the Meade f/6.3 Field Flattener threads on to the rear cell of any LX90, LX200 or other Schmidt-Cassegrain or Advanced Coma-Free model and is typically used with an Off-Axis Guider or T-Adapter. Reduces the telescope's focal ratio by a factor of 0.63: f/10 telescopes are converted to f/6.3. Simultaneously, the 41mm-diameter lens system helps flatten the field of Schmidt-Cassegrain models, significantly improving edge-of-field corrections. This handy Meade f 6.3 Focal Reducer/Field Flattener enables a reduction of photographic exposure times by about 50%, while producing an actual field diameter of 1.5" at the film plane.
