All the best Paul with ironing out technical issues. What was the reason to move the secondary forward?
Nice write up Eric. As I'm sure you are aware... one way to find out if it's tilt or colimation is to rotate the camera relative to the scope. If the star shapes, whatever they be, follow the chip (stay in the same place) then you have tilt. If they change place from rotating the camera, then it's likely you have an optical issue. The next issue to be aware of is, is tilt being introduced when rotating the camera
