Tube Ring Placement Effect On Optics

Placement is a non issue. Over tightening might be a problem.

I have found most people over tighten the tube clamps, they only need to be snug enough to hold the telescope.
I have seen some before that were so tight it dented the tube.
Moving clamp locations is just for ease of balance.

yes I meant tightening.

maybe the person worded their problem incorrectly, maybe they were getting some sag from seconday to primary , a bit of a warp from the tube rings , knowing the scope was collimated correctly before, pinching optics with tube rings is something i've never seen, optics are usualy free floating on a plate in most telescope setups, the tube is just a mere outside structure or even to just baffle out light ..

even most refractor lenses should be in thier own housing cell, i can only think of guide scopes or smaller scopes that have the tube and optics touching .

Thanks nFA. Been quite a while since I have heard that. But it all gets down to every thing connecting to the eye ball bone. 👁

Glad you were amused. It was a stream of consciousness post, the first thought I had.....
