Wide-angle image of solar corona

This image was made from 98 images obtained by means of four different cameras. These 98 images were chosen from totally 275 images in order to minimize the influence of rolling clouds. The position of the image in the sky is illustrated in this star map. A detailed map with terrestrial-North-up orientation is here.

ProcessingComposition of 98 eclipse images (10 (1), 4 (2), 23 (3), 61 (4)). Eclipse images calibrated by means of dark frames and flat-fields, aligned by means of phase correlation, composed by means of LDIC 5.0 software, processed using Corona 4.1 in order to visualize coronal structures. Final processing was done using ACC 6.1 software.
