Hi, all

I have an 8 inch mak, and believe that I can't use a laser collimator on it.

My reasoning is that the laser beam would hit the center of the (fixed) secondary mirror and return directly (hopefully) back to the laser collimator - ie: it would never touch the adjustable primary mirror.

is my reasoning correct? - I hope that I'm wrong, because I hate wasting prime viewing conditions to do star based collimation.
