Series 4000 f/3.3 CCD Focal Reducer/ Field Flattener: The revolutionary Meade f3.3 CCD Focal Reducer converts the optical systems of f/10 Schmidt-Cassegrain telescopes to f/3.3 for ultrafast CCD imaging, and with increased edge of field resolution and color correction. Mounted in its threaded cell, the f/3.3 CCD Focal Reducer attaches to the rear cells of all Meade LX-Series Schmidt-Cassegrain brands and other Schmidt-Cassegrain brands as well and reduces CCD exposure times up to 80%. The 3-element, 41mm clear-aperture optics are multi-coated to maximize light transmission. Included with each f/3.3 Focal reducer is a Varible T-Adapter that allows a range of f/ratios between f/3 and f/5 on f/10 Schmidt-cassegrains. The f/3.3 Focal Reducer may be used with CCD imagers of any brand and chip dimensions and produces spectacular results. Note, however, that the f3.3 unit is not recommended for use in either visual, DSLR, or photographic imaging applications. Meade Instruments Corporation
