Solar corona, Earth-lit Moon and stars up to 11 magnitude
It is a composition of 23 images taken with Canon EOS 5D using Rubinar 10/1000mm (modified Maksutov -
Cassegrain). Even though the Sun was only 22° above the horizon, the observing conditions were
surprisingly absolutely fantastic. It made possible to visualize not only the solar corona in very
high resolution but also the Earth-lit Moon and stars up to 11
magnitude. The brightest star (4 magn.) is slightly blurred by the motion of the Sun during
the eclipse. The blurring is not visible on weaker stars because they were recorded only on the
longest exposures which were taken in the short time interval near the mid-eclipse. The position of
the Moon represents the situation 54 seconds after the second contact i. e. 11:04:29 UT (18:04:29
local time). Both the display of the solar corona and the lunar surface in the resulting image are
beyond the ability of human vision during the eclipse.

Coordinate | 45° 43.251' N, 92° 06.837' E, 1223 m altitude |
Conditions | Excellent - clear sky, altitude of the Sun above the horizon 22° |
Optics | Rubinar 10/1000mm |
Camera | Canon EOS 5D digital camera (ISO 100 and 200) |

Processing | Composition of 23 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.
