APOD 3.3

This is the image of star trails set up at ESO's La Silla Observatory. To trace the graceful paths of the stars across the sky, set up your camera on a tripod aimed towards the sky and take pictures at intervals. This image is actually 250 consecutive one minute exposures over a 4 hour period looking towards the North. The North Celestial Pole, at the center of the star trail arcs, is just below the horizon in this southern hemisphere perspective.
