ProcessingComposition of 131 eclipse images. Eclipse images were calibrated by means of dark frames and flat-fields, aligned by means of phase correlation, composed by means of LDIC 6.0 software, processed using Corona 5.0 in order to visualize coronal structures. Final processing was done using ACC 6.1 software.
