CFF 140 f/6.6
CFF 140 f/6.6

The CFF Telescopes 140mm f/6.5 Oil-spaced Triplet Refractor is a remarkable instrument. It is a medium-size refractor that targets both visual astronomers and imagers alike. Its cell contains hand-finished, European lenses, which provide top quality planetary as well as unrivalled deep-sky views.

Paired with the CFF Field Corrector for Medium Format, the 140 mm F/6.5 is suitable for imagers using sensors bigger than full-frame.

This slightly shorter (915mm) focal length versions is aimed at deep-sky observers but will also suit planetary observers that want to enjoy the best correction possible at the eyepiece. The telescope has a colour correction which is tuned specially for planetary-visual peak wavelengths.

Note: this telescope is manufactured on request.

Main features:

  • 3.5″ rack and pinion type focuser from Starlight Instruments
  • dew shield with rotate & lock feature
  • highly portable, medium size refractor
  • Oil-spaced design for best possible light transmission & highest contrast.

 

* Overall length and weight depend on focal ratio, back-focus value and focuser
