I have had a problem with a scope I had it collimated perfectly but when I lined up on Saturn I had a perfect image of it but there was a flare on one edge. I finally found the problem one of the secondary vanes was broken and was offline towards the front of the scope all fixed now and everything looks great
Hehe... I had that problem once with my small newt. It wouldn't hold collimation. Took me a while to figure out one of the vanes two screws on the secondary block were loose. Drove me nuts for a while though. It's not something you'd think would happen.
Problem solved
