Thanks Trevor I really didn't want to touch the primary. It looks really well collimated anyway. I know what you mean when you say hard by your self haha! Found that out the other night, but I figured out which screw did what in the end. Only did VERY small adjustments, like 1/20 of a turn at a time, if that, and each time I noticed a small bit of movement, but it was an improvement. When you say the primary is fixed, does that mean it will never need adjusting if the scope is cared for properly? (i.e not dropping it or something)
Any thoughts on this website which talks about primary collimation?
