Here’s a nice video for milky way shooters, but more interestingly is the relatively inexpensive equipment used, the$600 Sony A6000 and$329 Rokinon/Samyang 12mm F/2 lens. This is mostly the same gear I use for still milky way shots, and seems to be the standard for budget minded people. Go here for the Rokinon 12mm review.
This guy used F/5.6 at 2 minutes for each exposure, but star trails were not a concern here.
