Hi Paul,Yes, there is coma but not so bad. A lot depends on what EPs your’e going to use as some of them make things worse and some better. If you’re really really picky you can get yourself a TV Paracorr and be done with it. Obviously for high magnification stuff coma is not an issue (at f/4.8 anyway).BestAndrea T.
