If you want the clouds to blur overhead in your photo, then you need to use a long shutter speed. Fortunately the lights from the Hyatt Regency Maui Resort and Spa on the palm trees and the hotel itself were just bright enough light them, but not over power the stars and clouds in the 15 second exposure. Also being prepared helps, and bringing along a small table top tripod that allows a 15 second exposure with no movement.
Technical details. Canon 5D Mark2 at ISO 800 for 15 Seconds with a Canon 16-35 zoom at 16 mm and f/5.0.
