Kim, Really a great wide-angle photo. This time of the year through November 15 is when I usually see from the Unitas, the really stunning zodical light reaching from the eastern horizon up to two-thirds of the way to the meridian. In your great photo, I can see: 1) The outline of Leo 2) Venus and Saturn 3) The keystone of Cancer 4) Open cluster M44 in the keystone of Cancer 5) and a bit of open cluster M67 exposed near alf Cancer - Kurt _______________________________________________ Sent via CSolutions - http://www.csolutions.net
Gosh, thanks for the compliments, everyone. A bit more info: I was fumbling around with equipment for awhile in the bitter wind. This photo was actually taken after the commencement of astronomical twilight. Notice the orange horizon? And yet, the zodiacal light was still very bright. Had I not had problems, the ZL might have shown up much better. At about 5:30 when I arrived at the spot that I'd previously chosen from which to photograph, the zodiacal band was clearly visible to a point on the central meridian where it intersected the Milky Way and, coincidentally, Mars. Further west, the haze and lights of Sanpete Valley made it difficult to spot. Rob, great pic of the Geggenschien! I've set that as one of my goals for the coming year. What are the details of the photo itself?

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
