cant notice any elongation besides corners, cropping might help show, I'm at work and no imagine tools, just web display.

After mirror flip wont the image have a tiny change in focal length as a result so stacking sets would get slight doubling that youre seeing as trailing? isnt this why many cats have mirror locks? plus the vibration from mirror movement.
