The image shows the solar white-light corona up to 6 solar radii as observed by an international team from Enewetak Atoll (Marshall Islands) on July 22, 2009.
To create this image, the authors combined 38 photographs taken using a 500 mm, f/6.3 Maksutov-Cassegrain objective and a Canon EOS 5D camera during the 5 minutes 41 s of totality. The weakest stars visible on the image are of about magnitude +10.
