Coalescing Baily's beads

This image is the result of numerical of 22 digital images and a single one image taken on a classical film. This combination makes possible to handle easily the brightness ratio over one to million and to record the phenomena lasting only a fraction of second. The diffuse light is caused by the cirrus cloud.
