William
Optics 2" 0.8x focal reducer / field flattener
This
quality 2” reducer/field flattener comes with a CCD camera
adapter and is suitable for refractors with focal ratios from f6
to f10. In addition to reducing the focal length by a factor of
0.8 for fast photography, it works as a flattener of the field
curvature for sharp, pinpoint stars in your images. It is
especially recommended to imagers using CCD cameras. Comes
complete with brass compression ring and dust covers.
Custom computer designed to increase image scale with the
flattest possible field for photography with fast Newtonian
Telescopes. This lens is suitable for use with f/3.5 to f/6
systems. It will turn an f/6 system into an effective f/9 or f/11
system. Excellent for planetary work and splitting double stars.
Both lens surfaces are fully multicoated for minimal light loss.
The Multiplier lens yields a flat field of optimum focus and is
ideal for use with flat field eyepieces such as the TeleVue
Naglers or Pentax XLs
