Thanx Leo, yes I found the 20 had very good reviews etc, very happy with it and it fits the emu real good on the horizon.
I haven't had the pleasure of a fast 14 of any kind but I often think what are like at the extreme edges, and wonder if they have the lens technology to keep the stars reasonably good out to the edge, if so, then you'd expect there be absolutely no problem with edge distortion in a 20, but - there is some ?
So I have to crop a smidge which is no problem, but how far out is a 14 producing pin stars from the center, 80% the way out, 85, 90, 95% the way out, just curious anyway so doesn't matter, they do however produce an awesome field and with Programmed Lens correction etc make their images quite a treat,
I dont have such upto-date progs anyway but I'm happy with what I have,,
Cheers ..
