Hi everyone.
I'm the proud daddy of a Skywatcher 10 inch Dob. Bought it second hand at the right price. Just spent all morning trying to collimate it with my assistant's help. Not sure it is right but I have read heaps so tonight will be the crunch. Now my problem is with the focuser. It slops around the tube so I got busy with some cardboard and packed it but I don't think it will last long. Can anybody suggest a suitable remedy (other than buying a Crayford). Maybe that will be the best option eventually.
