Can any provide recommendations for a battery that lasts 6-8 hours so I can photograph star trails all night long on my D600?
I may be taking 500 or more shots at 30 seconds each.
I am especially interested in a battery that is relatively small and light weight and would rather have just one than a half dozen EN-EL15’s.
Also, what is the best stacking software program for stacking multiple night star images for producing star trails? Do any of the programs work with RAW images?
