The filter is a very thin, delicate film that needs to be mounted in a cardboard carrier to mount on the lens. This one is made of poster board and masking tape.

This is the same lens that I used to photograph the annular eclipse on May 10, 1994, but on a much smaller format camera with fewer teleconverters stacked on the back. This combination is 800mm at f/12.6, in 1994 it was built up to 4000mm at f/63 on a medium format film SLR. With that combination, I didn't have the solar filter: I stopped the lens down to f/320 and stood a bit off to one side to view the image on the waist level finder so the direct rays of the sun weren't coming toward my eyes. That image series was vastly overexposed at f/320 and 1/500 second, but it was the best I could do.
