The Meade f/3.3 CCD focal reducer converts the optical systems of f/10 Schmidt Cassegrain telescopes to f/3.3, or that of f/6.3 Schmidt Cassegrains to f/2 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 Cassegrains and to other Schmidt Cassegrain brands as well and reduces CCD exposure times by up to 80 percent. The 3 element, 41mm clear aperture optics are multi-coated to maximize light transmission.
The f/3.3 CCD focal reducer may be used with CCD imagers of any brand and chip dimensions. Note, however, that the f/3.3 unit is not recommended for use in either visual or photographic imaging applications with APS or full-frame DSLRs.
