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.)
