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,

Do you have a webcam or planetary camera? Could you post a few pics of the airy pattern at focus, then IN and OUT of focus?
