Photo by @babaktafreshi | A large telescope at La Silla Observatory is used to explore the universe under the spectacular southern sky in Chile. I enjoy practicing techniques that reveal the night sky in a single-exposure photograph. After two decades in this field, I continue to embrace single exposures, which represent the joy of photography and the value of the moment. Most nightscape images are documentary—we do not add, multiply, or relocate natural elements, unless it’s for a creative illustration that is made evident to the audience. You would not add a moon or the Milky Way where it didn't exist in the frame; this topic is timely, as photo montages, double exposures, and fantasy edits become more popular in this genre—and are often posted without acknowledging the altered reality. I share these concerns and my personal techniques in the latest issue of Sky&Telescope magazine, from the nonprofit American Astronomical Association.
