Review on Thousand Oaks Optical Solar Filter Sheet: Perfect for Telescopes, Binoculars, and Cameras! by Oscar Thompson

A few months before the eclipse I bought a 10" x 10" sheet of this solar filter sheet. I've read dozens of ways to make my own filter caps for my digital camera, but I've settled on my own method. I have a box full of screw-on filters for different sizes of UV camera lenses. I simply picked a couple of filters with the cleanest glass and decided to put a solar sheet between the two filters. No cardboard, no tape, don't worry about destroying the solar film in the field. My wife has a nice craft tool for cutting precise circles, although with some care this could have been done by hand (I did have to do a bit of trimming). It's better to oversize than undercut! If the film doesn't fit snugly against the filter on all sides, direct sunlight will break through, and that's bad! I had so much film that I decided to make filters of different sizes: 72mm, 67mm, 58mm, 55mm, 52mm and 49mm. I only used the two large sizes during the 2017 eclipse, but now I have an amazing permanent set of simple solar filters that screw onto the camera for almost any lens I have. All photos of the Sun (except two unfiltered shots of the total solar eclipse) were taken with these filters through an old Vivitar 100-500mm manual focus lens fitted to a Sony a6000 crop sensor digital camera.
