Corona
Photographing a totality is a little tricky. There are roughly 15 f stops of dynamic range from Baily's beads to earthshine. By bracketing over 11 stops, many moods of the eclipse become visible. This image is a composite image with the corona being exposed at 1/15th of a second and the moon portion exposed at 1/2000th of a second.
