Tips for landscape+stars photography?
I need some tips and tricks for photographing long star trails.
Some of the questions I am thinking about are:
If combining multiple shots, how do you avoid gaps in the trails, especially if the camera is taking NR "dark frames"?
How dark should it be so that the twilight doesn't wash out the stars?
If taking super long exposures(hours), will my battery run out mid-exposure?
How to balance the exposure of the foreground and sky
