This is my first decent comet image I've produced with Nikon D200. I'm quite satisfied with the result, this a good point to develop skills further. 17P/Comet was imaged at Nuuksio nature park, on 4th Novenber 2007. Size was approximately 1/3 of full moon diameter. Image is made up of 21 separate frames, each 30sec @ISO800 with 300/4.5 MF Nikkor lens.
