Corona in white light and EUV

The innermost part of this total solar eclipse image was replaced by SDO AIA data acquired in EUV spectral range. 304 A, 171 A and 211 A images processed by means of NAFE algorithm acquired during the time of total solar eclipse were used.

ProcessingComposition of 55 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 6.0 in order to visualize coronal structures. Final processing was done using ACC 6.1 software.
