I’ve had a lot of people writing and calling me saying they can’t find anyplace with solar filters in stock. If that’s been your case, then there’s good news. You still have time to make your own.
A number of companies (like Alpine Astronomical) sell “Solar Filter material,” which is the same material used in many solar filters, just without the mounting material. And there’s still time to order a sheet. A friend of mine here in Kansas City gave me a call yesterday saying he’d bought one, and was wondering about the best way to mount it to his lens. I gave Dave a couple of suggestions, but he did an even nicer job than I would have. Then he sent me some photos with an explanation of how he did it, shown below. And if you’re looking for tips on how to photograph the eclipse next week, read this.
