An auto collimator involves some kind of mirror so the light path is folded a couple of times. The idea is to overlap and match all the corresponding reflections on each pass to increase accuracy.

Thanks for the info on this Marc, but it won't be much use to me since my telescope has a 1.25in eyepiece barrel.
The Catseye auto collimator is for 2in eyepiece barrels only.
