$195! Gulp! Are you visual observing with a 8" GSO (or similar) reflector? Are you doing any collimation at all at the moment?
However, I'll jump ahead and suggest that you grab the cheap 1.25" Cheshire ($35) and use that. (I'd even pull the cross hairs out! But that is me
Crosshairs in a short tube are a bit too much, I think).) I reckon that Cheshire will get you started, may well do all you need, and there are no batteries to go flat on you! If you use it after dark, you will need to shine your red light onto the 45 deg surface to see.
