The last pass of ROSAT? As predicted, ROSAT made a high pass over Tucson tonight - October 21st, 2011 in strong evening twilight. I was able to capture the pass with multiple 2 second long exposures using a 8mm full frame fisheye lens. The second image is a cropped version of the first. Shot with a Canon EOS 5D Mark II | Sigma 8mm @ F/3.5 | ISO 2000.
