Corona up to 6 solar radii 80 images were taken during 5 m 41 s long totality by means of a Canon EOS 5D digital camera equipped with my old well-tried Russian Maksutov-Cassegrain 6.3/500 mm. Unfortunately the absolutely clear weather several minutes before the totality was interrupted by a small cumulus cloud and a part of the total eclipse was lost. After careful inspection of all eclipse images, 38 images which were not influenced by clouds were chosen. These images were calibrated by means of about 300 dark frames and about 100 flat-field images. The resulting image is finally over my expectation and the influence of clouds nearly negligible. The position of the Moon represents the situation 136 seconds after the second contact i. e. 03:30:55 UT (15:30:55 local time). The display of the solar corona, lunar surface and stars in the resulting image are highly beyond the ability of human vision during the eclipse. The weakest stars visible in the image are of about magnitude 10. The stars are a little bit blurred by the motion of the Sun during the very long eclipse.

altitude of the Sun above the horizon 56-57° Optics Maksutov-Cassegrain 3M-6A, 6.3/500 mm Camera Canon EOS 5D digital camera (ISO 100) Exposure 1/250 s - 8 s Processing Composition of 38 eclipse images. 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.
