If you do not have your own darkroom I strongly recommend using color slide film for all types of astrophotography. You can get good results with color negative film if your local minilab staff are willing to experiment and learn how to make good prints for you. Go to a lab that caters to serious photographers. Even better, Tony and Daphne Hallas do custom developing and printing for astrophotographers. Currently, these workstations do not provide contrast control, althoug they do let you adjust color and brightness.
Fast films are grainy, and they usually suffer severe reciprocity failure.
That means their speed falls off in long exposures. The best films for most kinds of astrophotography are in the 100 to 640 speed range. For lunar and planetary work, you need extremely fine grain, and films in the 25 to 100 speed range are generally best. E200 Film are my favorites. Kodak and most other labs will push this film to 640 speed at your request.
