An important advancement in high resolution focal reduction systems, the Meade 4 element, multicoated f/6.3 Focal Reducer threads onto the rear cell of any Meade LX series mirror lens telescope or to other Schmidt Cassegrain telescope brands (followed by the Off Axis Guider, shown, or T Adapter) and reduces the telescope's focal ratio by a factor of 0.63: f/10 telescopes are converted to f/6.3; f/6.3 telescopes are converted to 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 percent, while producing an actual field diameter of 1.5 inches at the film plane.
