A 5-hour time exposure, with the fisheye lens aimed directly east, records star trails at 3 degrees south latitude. The 3 parallel blue trails in the center are the stars in the "belt" of Orion. Star colors are just as they appeared on the slide film. The sky is reddish because of fine red dust blowing all week long in the sky. To the naked eye, however, the sky appeared dark. Why do the center stars trails straight overhead? (See the next image for the answer.)
