Description
Series 4000 f/3.3 CCD Focal Reducer/Field Flattener:

The revolutionary Meade f/3.3 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- Cassegrains (pp. 16 - 57) and to other Schmidt-Cassegrain brands as well and reduces CCD exposure times by up to 80%.

The 3-element, 41mm clear-aperture optics are multicoated to maximize light transmission. Included with each f/3.3 CCD Focal Reducer is a Variable T-Adapter that allows a range of f/ratios between f/3 and f/5 on f/10 Schmidt-Cassegrains.

The f/3.3 CCD Focal Reducer may be used with CCD imagers of any brand and chip dimensions and produces spectacular results. Note, however, that the f/3.3 unit is not recommended for use in either visual or photographic imaging applications.
