Pentax XW 30mm /40mm in f7 refractor

I am also interested to hear about the Paragons in terms of edge correction.

How do they handle astigmatism at f7?

I used my old TMB Paragon 40mm in my 80mm F/6 (before I got the Mighty 31T5 Panzerfaust) and the correction at the edges was good. I spotted no astigmatism, but there was a hint of field curvature

FC is fine, but I detest astigmatism. Usually in long focal length eyepieces, you trade one for the other..
