A couple of mine, still a work in progress. I'm thinking of one of the usual variations on one of the usual arrangements of various phases of the event with these two plus two or three others. These aren't much different from others, except that they’re mine.
Camera was a Pentax 645Z, Pentax 400mm ED telephoto and Pentax SMC-A 1.4 teleconverter. The outer corona was obscured by high, thin clouds. Attempting to raise the exposure to see the outer corona, just washed everything out. But exposing only for the inner corona also revealed the prominences, which was a pretty good tradeoff.
For exposing the full sun, I used a 20-stop neutral-density filter on the front of the lens, but the diamond ring shot above was right before I put it back on after totality.
