There have been a few threads on this subject.
Instead of building a cradle for the laser and doing the spot on the distant wall I have been wondering about another method.
I have a few refractors at f8 f9 f11 and f12 all of which are in collimation with a Cheshire eyepiece. On all these refractors the GSO laser is 10mm off centre so if I adjust the lasers dot, using a refractor and moving it to the centre does that mean it is now collimated for use in a Newtonian?
Seems easier than the cradle and wall thing, or am I missing something?
