Re: [APML] Aurora images posted

Tony,
Wow.  Some nice greens captured there.  I was surprised to see
how
long you exposed those shots...?  Huge difference in exposure
times,
film speed, and f stop compared to Bobbys' shot.  Here were my
exp
times:  rg200 - 15sec - 2mins @ f/4;  rg1000 - 1sec - 1min @
f/4.  I
considered opening the lens all the way for my rg200 shots (28/2.8
lens),
but decided against it.  If they turn out I'll post them tomorrow
evening.
