I went for broke last night and took 60 pictures of Comet NEAT for my latest animation. You will need a fast connection to download it since it is almost 4 megs! It took me all day to process all those frames. I used Images Plus, Irfanview, Neat Image, Photoshop, and Gif Construction Set to make the animation. Camera was a 10D on a Televue 85, ridding piggyback on a C11/G11 unguided. I took 60 one minute shots 30 seconds apart at ISO 800 in my light polluted Austin Texas back yard. Someone needs to do one of these from a dark location to get more tail. I used the Angle Finder C to focus. You can see the animation here: http://www.pbase.com/image/29081600 Wait for the whole thing to load up and it will play smooth.
