We're none the wiser as to just what it is you are photographing at night: streetscapes, statues, desert, cityscapes, night sky, star trails, moonlit scenes... Each of these requires variations in technique and approach, and a couple (eg night skies, star trails) a bit of careful planning.
However all those scenes are included the the newJiffy Night Calculator. See attached pdf.
