Hi Dan nice report, the star test is revealing a problem for shaw . Getting softening at 155 x with an 80mm triplet ED. I would take a punt and say you have spherical aberration . Should you worry about it?
maybe send it back under warranty for a better corrected one?
These are probably questions you are asking your self!
I think It all depends what your happy with, but the first thing I would do is get a professional evaluation but hey thats me !
I hope that I have not depressed you Dan, that is not my intension,I could be wrong.
I believe that when you buy quality you should get It !
