I'm going on a camping trip next week, and am pretty excited to try and get some pictures of the stars. I was inspired by these wonderful pictures of the recent meteor shower: http://blog.flickr.net/en/2009/08/13/perseid-showers/ Anyway, I was just wondering if anyone could give me some aperture/shutter speed combos for capturing the stars on 200ISO b&w film. I'll be up in the Rocky Mountains far from light pollution. It's my first time trying this, so I'm expecting to do quite a bit of bracketing, but I was just looking for some ball park numbers. Should I bracket around 2 minute or 20 minutes? I plan on using a tripod and shutter release cable, of course. I was looking at The Ultimate Exposure Chart and according to that I'm at an EV of -4 to -6 which means a 4minute exposure at f/4 and an 8 min at f/5.6. Does that sound about right? Any tips on bracketing or nighttime star photography in general? Thanks bunches!
