Hey Chuck Your remarks got me wondering. How did you get enough distance between two shots to get any parallax? I don't remember how close Hale-Bopp got at closest approach, but I think it was a substantial fraction of an AU, wan't it? Did you pair up shots taken a few days apart? Michael
Same effect with astro shots. Reverse left-for-right, and you get stars in front of the comet, not behind it. I shot many pairs of Hale-Bopp and found this true 100% of the time.
