Baily's beads at the second contact

This image is the result of very complicated mathematical processing of two sets of images. The innermost part of corona was reconstructed using digital images taken by Friedhelm Dorst, the more distant part was created using images taken by Vojtech Rušin.

Processing20 different images (16 R, 4 D) were used for image creation. Images were aligned by means of ACC 6.0 Match II module (D) or by means of phase correlation technique (R), then processed using Corona 3.0 software. Final processing was done by ACC 6.0 software.
