I had the little scope out for a peek at Saturn tonight. After a bit, I pointed the scope to a bright star and went in and out of focus to check the collimation. Turns out the center shadow is noticably off center. I'm looking at the back of the scope, and see the 6 small Allen screws, in 3 groups of 2. I understand one screw in each group is a lock screw, and one actually moves the mirror. My question is which is the lock screw, and which is the collimation screw. I'm not worried about turning the wrong one to 'unlock' the collimation screws, but I figure I'd ask here in case anyone has experience with this scope, or can offer advice. I've been successful collimating my Z8 for many years, so I'm sure I can figure it out, but asking for any advice I can get seems prudent. I've never messed with anything but Newts. Thanks in advance.

 The first post has some tips on mirror alignment.
