Corona up to 8 solar radii

This unique eclipse image shows a huge CME propagating through the solar corona and Kreutz family comet shortly before it disintegrated near reaching perihelium. The full resolution version of this image you may download here. This image is oriented so that the solar North is roughly on the top. If you prefer the orientation as it was visible in the sky download this image version.

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.
