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.

Just the time between exposures was enough to put enough distance between them. The comet and me on the earth's surface were traveling in nearly opposite directions, so the few thousand relative miles between exposures was sufficient separation to show the effect. One of these days I plan to make the "digital conversion", then I can share more of these things. C. __________________________________ Do you Yahoo!? Yahoo! Finance Tax Center - File online.

Thanks Chuck. I'll bet with sufficient care in registration, a lot of lunar and planetary series could make some nice 3D shots, eh? Michael O

Very intuitive, Michael, well done. In fact I noticed, in retrospect once I got the stereo "bug", that some lunar eclipse sequential shots could be used as pairs. The moon looks like a BB hanging there in front of the stars. I've never taken it the next step, say, Mars, Jupiter or Saturn, but there have been sequences published in the magazines that had usable pairs. There are folks on this list who could easily produce excellent digital, high-powered, high-resolution planetary stereo pairs. Don't forget too the "artsy" composition with an earthly manifestation in the foreground, such as a shrub or saguaro, sometimes very well done. Imagine a stereo pair of a curtained aurora...
