ISS Star Trails

Don Pettit hat von Bord der Internationalen Raumstation aus langzeitbelichtete Fotos gemacht, die ziemlich trippig aussehen. Irgendwo zwischen Tron und dem Finale von "2001: A Space Odyssey". Das 23-teilige Album gibts im NASA-Flickr.
"My star trail images are made by taking a time exposure of about 10 to 15 minutes. However, with modern digital cameras, 30 seconds is about the longest exposure possible, due to electronic detector noise effectively snowing out the image. To achieve the longer exposures I do what many amateur astronomers do. I take multiple 30-second exposures, then ‘stack’ them using imaging software, thus producing the longer exposure."
