Sloppy I can believe - mine gets that way sometimes after a lot of twiddling, but it's a dawdle to adjust back up quickly.

Hi there Chris, Before the focuser went to the dealer I colimated the bare OTA. I then fitted the focuser to it & put the laser into the draw tube of the focuser. The laser didn't even appear on the target. Holding the focuser nice & solid, (with the draw tube fully retracted) I rotated it on it's axis. The laser appeared on the target, moved through an ark across it & then disapeared again. I haven't done the paper trick, but will try that when I pick it up later in the week.
