Improve your Meade or Celestron SC / Maksutov telscope with a really superb focuser. Mirror shifting will not be any problem any more. Additionally, you can focus more precise than with the standard main mirror system.

We do not recommend this focuser for fork-mounted SC telescopes. - Because of the focuser's length (112mm), it would hit the base of the fork mount at higher elevations.

The function of the Crayford's ball bearings is take over by a massive stainless steel rail that is fixed to the drawtube. Nothing can be bended any more. Lateral guiding is performed by ball bearings who only have to do this function - they don't have to deal with pressure loads.
