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)
• T-Max 3200 (black and white print)
• T-Max 400 (black and white print)
As you perfect your technique, try specialized films, that is films that are
designed or specially treated for celestial photography. 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 combinations were used. Or take unguided sample photos
of various parts of the sky while the drive is running. Always take exposures of
various lengths to determine the best exposure time.
