Hi, i need some advice as to where i can obtain a crayford style SCT focuser to fit to my 5" Mak, it has a 1 1/2" visual back, not 2" like most, and all the focusers i have seen so far are all 2" fitment. Surely someone makes one with 1 1/2" fitment, or maybe a reducer adaptor so a 2" will fit.

Or if anyone on IIS has one they wish to sell, pls let me know.
Cheers.

You can get a small adaptor which replaces the 1.25" on the rear of the scope and gives you a SCT thread ( identical to the Celestron/ Meade thread) This allows you to use all the Standard SCT accessories; focusers, flip mirrors etc etc.
The only real problem is that the internal baffle on the Skymax is only 28mm so adding anything large (ie 2" fittings or eyepieces) is a waste of time.
