Hi Kim The Gegenschein shot is a 5 minute exposure w/ a 16mm Rectilinear Fisheye at F4, ISO 800 on a Vixen GP-DX mount. I had to take about 8 shots before I found a combination of exposure settings that barely showed the Gegenschein. I then worked the shot in CS2 until I knew it could be seen by all. It was a dim feature that is barely there, best noticed w/ averted vision. A really dark site helps and I was surprised because the Air Force Optical Station next to us has bright red ground lighting that ruins the north night sky, but it didn't bother the shot almost at zenith. the best thing is that YOU did it and it was done good. Aloha Rob
