Then I think you most likely you have the problem with the focusor. Those focusors move around very badly. It does not take much flex to see different results. I found that even at different angles the collimation would shift quite a bit and yet it appeared to be reasonably firm.

I was not clear about the baffle area. I did mean the retaining ring. Sorry for the confusion.
