Star trails are caused when a camera is mounted on a fixed tripod, and the Earth moves below it during a long exposure.

Comet Hale–Bopp 1997 

Hale-Bopp (C/1995 O1) graced the sky for many weeks, much brighter than the famous Halley's Comet.
Halley last appeared in 1986 when it was a naked eye object easily seen with binoculars.

This comet was discovered independently on July 23, 1995 by two observers, Alan Hale and Thomas Bopp. In January 1997 it was bright enough to be seen by anyone who looked for it, even from large cities with light-polluted skies.

 These images were recorded with a Pentax SLR camera on 400 ISO 35mm film.
