Thank you Greg. I appreciate your kind offer. My problem isn't that the filter is too dark, rather a diagonal flare across the sun that caused a fuzzy lower limb. What I've done so far is to make two circular rubber discs backed by steel washers a little smaller than the filter. Sandwich the glass between these in a vice and rotate the frame so as to bring the flare horizontal rather diagonal. Flare is still there but now I get a distinct edge to both limbs. I'd still like to get a new filter but I can live with this for the present.
