Outer corona
Even if the total solar eclipse of 1995 October 24 was very short on the observing place, only 50
seconds, it was long enough to take sequence of eight images covering the solar corona from the very Moon's
edge up to seven solar radii. The new composing method enables to create exact image including the
shape of the Moon. The black object in the image center is not a black circle covering the part of
image blurred by Moons's motion but sharp image of the Moon taken with 1/15s exposure. This single
image was used for reconstruction of the nearest neighborhood of the Moon. The more distant parts of
solar corona were reconstructed using all eight images.
