A clear and moonless sky yielded this time exposure photograph of Hale-Bopp March 30 in the Rocky Mountains 69 miles southwest of Denver. The blue tail, not readily seen with the unaided eye, is made up of ionized gases. The details: 50mm f1.4 lens, Kodak ISO 1000 negative film, 30 second exposure. The viewing site, 10,400 feet above sea level, contributed to the clarity.
