1. Essential gear for astrophotography:
A camera with good high-ISO performance
A wide-aperture wide-angle lens
A tripod and head
Other optional gear:
A shutter release cable or wireless remote
Spare batteries
2. A bright moon means sparse stars

New moon - first quarter - full moon - last quarter
The Milky Way is hard to capture in the days around a full moon
3. Exposure: the 500 rule for star photography
Maximum exposure time = 500 / full-frame-equivalent focal length
Aperture: wide open
ISO:2000-6400
A common settings combo: 16mm, 30 seconds, f/2.8, ISO 3200
4. Stars are usually focused manually. The infinity mark on most lenses deviates somewhat from true infinity, so it's best to focus manually using a bright star on the rear screen. Turn on the camera's live view, zoom in, find a fairly bright star (or a distant light, or the moon), and slowly turn the focus ring. When the star shrinks from a blurry disk into a crisp point of light, focus is nailed.
