This shot is the second of a series taken on Thursday night (11/25/07). I took this shot of Comet Holmes without the barlow used in the first image. This (slightly) overexposed the inner portion of the comet, but nicely pulled in the surrounding stars to put the comet in perspective. Click on the image to see a higher resolution version.

For this shot, I used the Canon Digital Rebel XTi for a 15 second exposure at ISO200. I was shooting at prime focus through my Astro Physics Starfire 160 refractor. This is a pretty quick system… at f/7.5 over 1200mm focal length.
