Are you looking for the world’s best APO refractor ? You have just found it !!

You have found what you should be placing at the top of this list in your research, CFF’s fully oil spaced APO triplets.

This is a bespoke custom hand crafted exotica level triplet fully oil spaced APO refractor that is better than any telescope made anywhere globally by any manufacturer.

CFF Telescopes are a premier European manufacturer of the highest quality and capability. CFF are different from other manufacturers – CFF use an “Oil Spaced” optic process.

Oil spacing enables higher performance due to:

  • Higher optical quality is required to hand craft the lens in the first place (an air spaced does not need to be anywhere near as accurate optically)
  • Less contact points between the light waves entering the lens pack & the surfaces of the lens elements themselves – enabling higher magnification & resolution
  • Shorter cool down time

These advantages are only available in a fully “oil spaced” refractor design.

This is why the best refractors ever made in history are all fully oil spaced !

Please feel free to call Cris to review, you will find our discussion of optical physics on this matter illuminating.
