I assume when you rotate the corrector, the camera rotates with it, and there is no rotator in the mix?

If the focuser board is out of perpendicular from the optical path, surely it must be thicker on one side than the other, no? as the telescope tube has to be cylindrical. I think you've done the right thing with the measuring tools and rotating the corrector (and camera with it?)

Atlas adapters are dovetail? if so, you can still pack them out with a shim pushed in between the two parts, and the dovetail just wont tighten up so much, if i understand you correctly.
