Someone looked at the Mirror images I posted, and said that he didn't think I had a turned edge.
So I did the test of cutting in until only the right-hand diffraction arc is left, and comparing that to the left-hand arc.
If they are approximately the same, then either no, or just a slight turnage on the edge.
I cut out a Couder mask, and will be doing some parabola measurement this weekend.
I'll also post more images with the clean camera lens. With and without the Couder mask in place.
Wish me luck on the final (I hope) few hours of polishing.
