I think you'll get more replies in https://www.cloudyni...ep-sky-imaging/. The images are quite small as well so it's hard to tell, when you post there, I'd suggest you include crops at 1:1 scale with the areas you're asking about.
One thing to try is to test with targets in various directions of the sky, which makes it easier to tell if it's sagging in the optical train, for instance. You may want to take a photo of the camera's position for each test, so later you can correlate the image orientation with real world orientation.
