Hi Patrick -- Extremely cool! I'm sure you can figure out the exact distance to the target through these images.

It's one of those things I'm sure has been done before but I wanted to try it myself. They used the 2 meter Faulkes Telescope North on Haleakala and I used a C-14 here in Utah to simultaneously take images of (3833) Calingasta which is currently about .45 AU from Earth. Here's my first (and admittedly "quick and dirty") effort to display the images side-by-side: http://users.wirelessbeehive.com/~paw/temp/parallax01.jpg Fun night, patrick 718 _______________________________________________ Utah-Astronomy mailing list Utah-Astronomy@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy Visit the Photo Gallery: http://www.slas.us/gallery2/main.php Visit the Wiki: http://www.utahastronomy.com
