Model:
Atik 0.5x Focal Reducer

Description
:
When used with the
phillips webcam this simple and cost effective device works as a .5x
reducer. When coupled with the "shortie" adaptor and a Mintron or Watec it
functions as a .66x reducer. This reduction ratio is very useful for deep
sky performance on most reflectors and refractors of the F4-F8 range. I have
found that larger instruments (above 6") benefit most from the reduction in
the F ratio. Adding the C/CS adaptor supplied with each video camera results
in a reduction of about .6x, but requires more focuser in-travel than many
instruments can deliver, without modification.Higher focal ratio instruments
such as SCT's and MCT's are better off with the long telescope adapter.
Using the focal reducer in this situation can result in a focal reduction of
around .4x. Achieving focus is not usually a problem with these instruments.
F10 + telescopes are transformed for deep sky work by a large reduction in
the focal ratio.
