There must be something wrong Astro, the 2" adaptor that fits onto the focuser so that you can use 2" eyepieces is about 56mm deep[from memory].
How far in does your laser collimator have to go? My laser collimator slides in
fully, which is about 25MM. I don't have the scope any more, so I can't compare anything, but I don't remember any stop in the draw tube. Are you using the adaptor when collimating? The stop is not something to do with using 1.25" eyepieces is it?
