Yes the donut moves away from the bright star as you scan across.
Thanks you are confirming it is an internal reflection. I will look into the ir cut filter solution, that seems a cheap fix (if it works).
I will also try a small change on the spacer between the camera and reducer.
It might be a while until we get some reasonable weather the wet seems to have started and cloud is king.
