Forster said, "Only connect". Edward, If you look closely at the picture you will see some movement of some of the other brighter stars. The bottom star is the brightest and has enough light to record on the CCD camera while moving. These picture generally take several minutes of exposure so only the brighter stars would show the streaks during the quake. -- Jim Hannon http://soli.inav.net/~jmhannon/ 42,11.90N 91,39.26W WB0TXL _____________________________________________________________________ Public Seismic Network Mailing List (PSN-L)
