Josh,
Sorry you are having so much trouble.
Have you tried rotating the camera 90 degrees and repeating the experiment?
Can you eliminate the secondary support? That is, have you slewed to a position where you get elongation and re-checked collimation? Could it be focuser shift?
Also, maybe you should turn off anything in software that might be contributiing such as PEC and Protrack, and then take even shorter exposures. Maybe your model isn't great at 40 degrees and Protrack is moving the scope??? Also, if you take much longer exposures in an area where you get distortion does the distortion increase at all over time?
PS You should have come to AAIC because Rick Hendrick was there and maybe he would have been able to help! There were more experts in attendance than you could shake a stick at!!!
