I'm going to set an Asahi Pentax Spotmatic on a tripod tomorrow night after the moon sets, and try to catch some Perseids. I'll be using a 28mm lens at f/2.8. Will be shooting color, I have some 400 speed film, and also some 800. I plan on leaving the shutter open for maybe 4 hours. Which would you use? I'll be at a dark sky site, but I think the faster film would pick up more sky glow (there is a town about 30 miles away). So asking for suggestions. There is a camera store near me that still stocks film (!) so if other speeds are suggested, I could get something else.
I would appreciate opinions!
