I sometimes wonder after hearing fairly varied accounts of the field curvature
in the 14mm XW, which I see mostly being testing in mass produced mirrors.
If the varying performance of the mirrors have something to do with this. I've
tried my 14mm XW in a variety of scopes, in some it performs better than in
others.
I have tried a Hyperion, cant remember what FL it was. But I would have to
say it was the closet thing I've seen to the performance of the XW in regards
to contrast.
