I didn't see a sticky here, and not even sure if this is correct place, but I figured if anyone knows the answer, they would be here.
I wanted to try and do some shots of the stars. Lately here has been quite warm, so night time shouldn't be so bad. I'm going to drive up north to where it's more country to avoid light pollution and what have you.
So, my question is, should I leave noise reduction on? I mean if I do a 10 min exposure, the NR will take 10 min. Is there any big pros or cons to using camera NR or doing NR during post? Also where I plan on shooting from shouldn't be any cars, but if a car or two do happen to drive by, what are the chances of their lights effecting a long exposure? I will more than likely have the camera mounted on top my truck, so it should be well overhead.
If you have any other recommendations, please let me know, like maybe exposure times, specific apertures etc. ND filters? Thanks Everyone!
