International Space Station Expedition 41 over the DDO. I knew this was going to be a good pass, so I opened up the dome, and moved the 74″ scope into a position that made it visible in the image. I turned on the red lights in the dome for fill. The ISS is a series of 15 stacked images. Shot with a Canon 5D Mk II and a 20mm 2.8 lens. Subs were 9 seconds at f/2.8 at ISO 320
