| 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, or 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%.
The 3-element, 41mm clear-aperture optics are multi-coated 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 SCT?s and between f/1.9 and f/3.2 on
f/6.3 SCT?s. 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. The f/3.3 CCD Focal Reducer
