This image of comet 17P/Holmes was taken last night using my 70-300mm lens with the camera mounted on the front of our Spacewatch 36 inch telescope - in essense, using our big telescope as a glorified guide scope. This image was taken at 92mm focal length with an exposure of 2 minutes at f/5, ISO 400.
