Mark,
This is a pair of nice images, also.
I am not at all sure that I have set the optimum position for the ring adjuster. You seem to have the filter near line center, and the image pretty well centered on the "hot spot". I seem to have a fairly intense hot spot, not well centered in the field of view. Could you explain your adjustment procedures?
Thanks,
Harold
