DescriptionDigital composite of the solar corona from 28 frames. A total of seven 11-stop sequences (from 1/500 to 2s) were acquired during totality, of which only the best four (exp. times 1/15s, 1/8s, 1/4s, 1/2s) were used in the composite. In spite of the presence of high cirrus clouds, the wispy details of the inner corona are clearly visibile.
