The link I gave up top has all the info about viewing and glasses and making a pinhole box etc etc.
I ran up to the welding supply store and he said he's seen peak business and is moving shades like candy. He was all out of what I needed, but he's been advised to give out coated 5&9 and stack them. So that's what I got. 2 sets. I taped them together with clear packing tape so I'm set. It's actually pretty neat. Not all I need is to figure out how to get Mr. iPhone to focus manually. Mr. DSLR don't like it either on manual mode. View attachment 99766View attachment 99767
55% here and the stacked welding glass plates worked . Very good clarity. Beautiful weather in the Laguna Mt's made for a memorable day.
