Meade® f/3.3 CCD Focal Reducer/Field Flattener

The f/3.3 CCD Focal Reducer marks a major advance in high-resolution focal reduction systems. It permits ultra-fast CCD imaging and reduces CCD exposure times by up to 80%. The f/3.3 CCD Focal Reducer threads to the telescope's rear cell and may be used with CCD imagers of any brand and chip dimensions to produce spectacular results. The 3-element, 41mm clear-aperture optics are multi-coated to maximize light transmission.A variable T-Adapter that allows a range of f/ratios between f/3 and f/5 on f/10 Schmidt-Cassegrains and between f/1.9 and f/3.2 on f/6.3 Schmidt-Cassegrains. Note, however, that the f/3.3 unit is not recommended for use in either visual or photographic applications.
