Heres the corners. Only the bottom left shows some elongation. Im sure it could be fixed with precise collimation. I didnt collimate the scope before the imaging session.

Thank you Sal ! looks really great, the reason I asked for unstretched version was to see if stars change their size during processing. I shot this galaxy last year at 1700mm FL using meade SCT, but had terrible time processing it since stars will get out of shape dramatically during stretching, so I was not sure was it the optics or my subpar processing skills.
