Also take off the focuser tilt adapter for now. So just thread the focuser to the back as is.

Hi Marc
Yes the donuts are slightly brighter on one side. In focus stars look ok but out of focus stars are brighter on one side. SGP picks up the bright spots as stars soo it fails the auto focus most times.
Thanks for the tip - I’ll see if I can remove the focusing ring - I did try to set it back to zero adjustment - ie set all screws back to zero then out one turn in an attempt to get a starting point.
Having three points of adjustment increases the complexity,
