[APML] What's the Longest Exposure for an ASA 800 Film

["Thomas W. Earle" <twade@bmi.net>]

In preparing for the Geminids, I'm trying to figure out what is the
ideal/maximum exposure at F/2.8 using NPZ Fujicolor 800.  I'll be
using a Pentax 67 camera so there's not too many film choices left
in the medium format arena, especially color negative films.  I have
a very dark sky with an elevation of 4000 feet.  Here's a link to a
light pollution map of my observing location:

I used some old Fuji NGHII 800 during the Perseids which I exposed
for 10 minutes, but a few shots seem a little muted; however, the
film is a little over a year past its expiration so I'm not sure if
I exposed too long or not.  I'll primarily be shooting around Orion
area which should be about at an altitude of 40-45 degrees at its
highest.  I plan on doing some testing over the next few months;
however, it's all dependant on mother nature.

Any comments or advice would be greatly appreciated.

Wade
