When getting started, use fast films to record as much detail in the shortest possible time. Here are proven recommendations:
•Ektar 1000 (color print)
•Konica 3200 (color print)
•Fujichrome 1600D (color slide)
•3M 1000 (color slide)
•
•
As you perfect your technique, try specialized films (i.e., specially designed and/or treated) for this type of astrophotography. Here are some popular choices:
•Ektar 125 (color print)
•Fujichrome 100D (color slide)
•Tech Pan, gas hypered (black and white print)
•
There is no exposure determination table to help you get started. The best way to determine exposure length is look at previously published photos to see what film/exposure combination was used. Or take unguided sample photos of various parts of the sky while the drive is running. Take exposures of various lengths to determine the best exposure time.
