Not Useful for Beginners
Purchased this to learn to collimate my 10" reflector. Looking at the web page, it's not clear that you have to remove your primary mirror to put their target stickers in place. They then talk about using their Farpoint Laser Collimator (in...

Works particularly well
After spending some time comparing this tool to others in my tool box, I've really come to appreciate the fact that this tool "self centers" because of the way it press-fits into the focuser. This makes the tool's placement extrem...
