Frustrated Patrick here... After finishing with the EP I worked tonight I shot a few 60 second images of Comet Hartley. First through the clear filter, then one each through R, G & then B. Each individual shot looks fine but when I tired to put them together to get a pseudo color shot it looked terrible. And no amount of messing with the various settings helped. So I posted the set of originals here as a ZIP file. Maybe one of you can make the magic work. http://users.wirelessbeehive.com/~paw/temp/103.zip patrick p.s. I need some of Joe's patience.
