I'll check out the options (Planetarium & a welders supply) and post up what I come up with. Chuck- I'm curious about your design for bino solar filters; I've been giving something like that some thought. My guess is you are adapting a [large] PVC fitting to cover the binoculars? A while back somebody posted that he had some Baader film for sale, but never replied to my email. If that person is still out there, I'm still interested.... I can't get out to SPOC after work in time for the eclipse, so I'm going to observe it from Churchill Jr High on Wasatch between 3900 S & 4500 S. If anyone is in the same boat and wants to join me and my rug-rat crew, please do... Joe Borgione

I plan to make dual solar-filters for my 70mm binos for this eclipse, from the Baader material and PVC pipe.
