Fig. 23: Totality of the lunar eclipse of 3/4 March 2007. One can see the different colours ranging from red, yellow and blue. The different colours are caused by the earth's atmosphere that looks like a glowing ring when seen from the moon during the eclipse - like a dusk. Unfortunately this picture is an unsharp combination of 4 pictures with high ISO number because I didn't have a motorized mount and therefore one couldn't make longer exposures than 1/2 second.
