Baily's Beads at the second contact

This image is the result of numerical processing of one Baily's beads image taken with 1/1000 s exposure and 21 more images taken later with longer exposure time. These 21 images taken later after the Baily's beads had disappeared were used only for improving the corona contrast with no influence on the image brightest part. The processing of such a number of images enables to enhance even the finest details in the inner corona and to create such an impressive picture.
