Thanks for the kind words, Chuck. There are so many things I would have done differently. A filter sounds like a nice thing to try. If we'd had a nice, clear sky and I had realized earlier that the comet would be appearing that night, I would have started sooner, setting up my telescope and shooting through it with my little CCD. This comet seems rather small, but I don't know if it would have fit on my CCD chip; if not, I could have made a panorama to get it all in. As it was, I shot a digital camera with an unexciting telephoto lens, mounted on a little tripod. Rightly worried about vibrations, I shot at a fast speed. It was something like 1/50 sec. at the fastest ISO my digital camera could put out, 1600. I couldn't open the telephoto's aperture any farther so the views were underexposed. Using 1600 meant the pics were grainy too. I stacked some of the clearest shots. But stacking meant using photos from slightly different times, which blurred the foreground mountains (because they were in different places relative to the comet when I stacked the views). In retrospect, using the equipment I had with me, what I should have set it for a longer exposure, maybe a 15 seconds, then used the old hat trick to let the vibrations die down. If the exposure was so long that the comet and stars moved, I could have reduced it somewhat -- it certainly would have been better than 1/50 of a second. Anyway, I may go again if it clears up in time. If first you try and don't succeed, fail, fail again. ... Joe
