HelloIt’s a while since I owned a Newtonian, but from when I did, if it really is only very slight, and I mean veryslight, then I would suggest its nothing to worry about. How do the Airy rings appear on a star test? Are targets such as Jupiter clear, sharp and crisp through a range of magnifications? Again, if all looks good, then I wouldn’t worry.
