Description

Composite of 44 exposures. Each side of the 'beads' contains 20 - 1/4000s images taken 0.75 seconds apart. The center image is a 4 second exposure for the earthshine and a stack of 3 - 1/125 second exposures for the corona.

The 'beads' effect is caused from bits of sunlight peaking through the uneven surface of the moon just before and after totality.
