I got a huge tilt in both of my imaging train and thanks to CCDInspector to validate my hypothesis that there’s a hug problem in the imaging train of both of my astrophotography setup. The camera I used for both is the ZWO ASI1600M-Cool and it’s good to see that the curvature is different meaning that I can eliminate the camera as the source of the problem. I may also need to use my Canon 5DMarkIII and Canon 7D/SL1 cropped sensor to validate my findings.

This could be my next project this weekend and will take the opportunity because it’s full moon, no image capture.
I couldn’t believe of eh curvature and amount of collimation for both of my astrophotography rig.
Did you track down the problem? Where was the tilt in the image train?
Yes, it was on the focuser draw tube. I did some cleanup and tightening of the hex screws. It helped but not completely removed it.
