Meade f 6.3 Focal Reducer/Field Flattener #07545. For Meade Schmidt-Cassegrain models. Improves edge-of-field correction and reduces exposure times by close to 50%. Threads into rear cell of any Meade SCT. Threads into rear cell of any Meade SCT. May be used to increade field of view and reduce magnification for visual applications.
An important advancement in high-resolution focal reduction systems, the Meade 4-element, multi-coated f/6.3 Focal Reducer/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 accessory enables a reduction of photographic exposure times by about 50%, while producing an actual field diameter of 1.5" at the film plane. Use of this focal reducer is not recommended for 35mm photography or larger CCD chips with Meade Advanced Coma-Free (ACF) models as field correction is not needed.
