Neal's Comet Hale-Bopp Pictures

I took these from the (wonderful!) Malheur Field Station just south of Burns, OR. It is a nice dark spot in southeast Oregon, latitude 43 15', longitude 118 55'. They were taken on 1997-03-28 at about 21:00 PST (GMT - 8 hours). The comet was pretty close to Dec 45 20, RA 1h 21m.

I used Kodak RF 1000 film.

• This wide angle shot (28 mm lens) shows both tails, and the Andromeda galaxy (2.9 million light years away) is visible below..., along with the Milky Way in Cassiopeia (the "W" constellation in the upper right). This exposure was probably 30 s.
• This 49 mm lens shot has a satellite trail in the lower right, which I also got on two other exposures. This exposure was probably 30 s.

I solicit advice on converting Kodak PhotoCD images to good jpg's for the web, and in particular, how to pick the right colormap for cross-platform viewing on machines with only 256 colors.
