Meade's #07567 f/3.3 CCD Focal
Reducer/Field Flattener converts f/10.0 Schmidt-Cassegrain telescopes to
fast f/3.3 system, and a f/6.3 aperture scope becomes an astoundingly
fast f/2.0!  Ritchey-Chrétien f/8.0 systems convert to f/2.64 effective
apertures.  The device yields wider fields for imaging deep space
objects and better color correction and edge resolutionas well, as
effectively reducing exposure times by as much as 80%.

The Meade f/3.3 CCD Focal Reducer/Field Flattener attaches to the rear
cell of Meade LX-Series Schmidt-Cassegrains, RCX400 Ritchey-Chrétiens
and Celestron Schmidt-Cassegrains with apertures between
5.0-14.0".  Your CCD camera attaches directly to the reducer using the
supplied T-threads, due to the reducer's very minimal back focus.  This
is a concern; even adding a color filter wheel between reducer and
camera usually adds excessive distance to retain reaching focus.

The
variable T-adapter included with this device allows the choice of f/3.0
or f/5.0 focal ratios with f/10.0 Schmidt-Cassegrains, f/1.9 or f/3.2
focal ratios with f/6.3 systems, or f/2.4 or f/4.0 focal ratios with
f/8.0 Ritchey-Chrétien designs.

Multicoated 3-element (41mm effective clear aperture) optics maximize light transmission
