Hi everyone,

I've got a skywatcher pro 180 mak and need to collimate it but have lost the instructions and dunno what the 3 sets of screws on the back of the scope do. One obviously moves the mirror and the other locks it in place but I have no idea which is which.

Also do I need to loosen all the locking screws and collimate and then relighted them all or only loosen the lock associated with the collimating screw that I'm using if I need to adjust only one of em, hope that makes sense.

Look forward to any help and I'm getting desperate to get the scope out for some photography as its been ages since I've done any scoping.

Cheers
Mike
