This was taken in Mount Bromo, Indonesia. Shooting the Milky Way is not that hard but you need to do your homework. Let me list down a few important point.
1) Find a dark sky: Do take into consideration of the Lunar calendar. A full moon night will ruin all your other planing.
2) Use a Tripod: Most of your shot will be in 20-30s so you will need a tripod!
3) The “500 rule: Basically, you to divide 500 by the focal length of the lens you’re using. So, if you have a 24mm lens on a full-frame camera, you will set your shutter speed to 20 sec. (500/24 = 20.83). If you’re working with a crop sensor camera be sure to account for the crop factor (typically 1.5 for Nikon and Sony, 1.6 for Canon).
