Meade - Series 4000 f/3.3 CCD Focal Reducer: £128.68

For ultra-fast CCD imaging

The CCD Focal Reducer converts the optical systems of f/10 STCs to f/3.3, or f/6.3 SCTs to f/2, f8 RCX's to f2.6 for ultra-fast CCD imaging with increased edge of field resolution and colour 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 SCT brands and reduces CCD exposure times by up to 80%. The 3-element, 41mm clear-aperture optics are multi-coated to maximise 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 SCTs and between f/1.9 and f/3.2 on f/6.3 SCTs. The Focal Reducer may be used with CCD imagers of any brand and chip dimension but is not recommended for use in either visual or photographic imaging applications.
