Sprites observed from Switzerland 6-7 September

Last night when the EuroSprite team caught only one sprite due to cloudiness over the cameras, amateur astronomist/photographer Mark Vornhusen caught many sprites from Gais, Switzerland that appeared near the French-Italian border, some of which he posted to a German weather forum: http://www.wetter-zentrale.com/cgi-bin/webbbs/wzconfig.pl?read=741655
Among the images he obtained is a remarkable colour image, showing sprites as weak red patches. He obtained this with his digital SLR camera the Nikon D70 set at ISO 1600 and using a bright 50mm f/1.2 lens - to my knowledge he is the first person to succeed in that! Note that the same sprite was captured by his low-light video setup, showing in fact a very bright sprite event. Congratulations to Mark!
