Thanks Lars. I dismantled the objective last night, cleaned all surfaces of the doublet and found that the elements had rotated 120 degrees from the alignment marks. Once realigned and reassembled the view improved about 100%.
I then dismantled the eyepiece and cleaned it. It works but with my tired eyes was a challenge, so this morning I converted a 25mm plossl and fitted it into the focuser tube and the views are excellent !!!!
The next step will be to cut a matching thread on the plossl body. That probably has not been done very often.
I think I will store the original eyepiece in a safe place.
