I'm testing something that could be very very valuable to beginners, if proven to be correct

So to prove if I'm correct or not, I need distorted data; distortion at the edges, stars getting circular towards the middle.

Basically anyone who's not using a field flattener on their refractor/other optical designs or a coma corrector on their newt, plz give me a small sample of some of the data from your rig(s) (and doesn't have to be a lot)
