September 2000: The Gegenschein

23 October 2000, 21:40-22:10 UT (30 min exposure), f=16mm f/2.8 (fish-eye photo, diagonal = 180), Elite 400, from Mt. Matajur. After two hours the Gegenschein has rotated in the photo frame which proves that it is not a camera or film artifact. The darker sky above Slovenia (horizon on the left) compared to Italy's (right) allows us to glimpse the red nebula of Lambda Orionis.
