Fish-eye images

The following fish-eye images show the course of totality at the Shadow-tracking expedition observing place at Klyuchi ionospheric observatory of Russian Academy of Sciences near Novosibirsk in Russia. The images were taken by means of Canon EOS 300D camera equipped with a 2.8/29 mm lens and a fish-eye adapter. The camera was controlled by means of a home-made timer made by Pavel Štarha. Worth mentioning is the difference of sunlight color between the first and the second image. The first image was taken at the time when the crescent of photosphere was shining very strongly and the photospheric light dominated. Whereas, the second image was taken at the moment when the crescent of photosphere was so narrow that the red radiation of solar chromosphere was prominent enough (in comparison to white photospheric light) to change the color of solar radiation significantly. The same effect in reversed order can seen, but only slightly, on the last pair of images. The reason for the effect not being so prominent is that the penultimate image was taken too long after the third contact.
