I have some of those glass-plated solar filters. Is there a worry about them too? I looked at some under strong light and a couple seemed to have extremely light scratches on the glass, not really scratches, just like marks where they were cleaned. When I looked at the sun with them I saw nothing odd. What's your take on this, Chuck? Best, Joe
