The Earth is constantly spinning at about 1000 miles per hour, so when you take a long exposure to capture the dim light of the stars at night, you'll end up with streaks of light rather than the pinpoints that we perceive when we look up at the night sky. If you are looking to capture the stars as points rather than as streaks, you'll need to use a high ISO and a relatively short shutter speed, usually 30 seconds or less. For this photo of a Masai man taken at night in Kenya, I used flash at low power to selectively illuminate the man beneath the Milky Way. Canon 5DIV, Canon 11-24mm f/4 lens, ISO 6400, f/4, 30 seconds.
