Rick: The best film for aurora photography is Provia, by Fugi, ASA 800. It is widely and easily available in local stores. Royal Gold ASA 400 by Kodak is also no too bad. For aurora photography, as you probably know, you go for short,fast,expensive lenses. My favorite is the Nikkor 20 mm f2.8. Always stop the lens down one stop. For average central Alaska aurora (shimmering curtins, etc) use 10 to 30 seconds at f2.8. For really spectacular breakups an corona, when they are bright, you can get good results with about 5 to 10 second exposures. Anything exposed longer than a minute will almost always have too much blur from the E cross B electromagnetic drift and lose esthetics. Remember that the light is coming back real fast around equinox. Photoraphy of the aurora in late March is problematic. Too bad we're in Tucson, cause otherwise I could meet with you in my home town of Fairbanks, aurora capital of the world. Good luck. Glenn Shaw
