Night photography has been growing in popularity recently with advances in digital photography equipment and many people are taking advantage of the incredible colors and contrast of the world at night. But, like all photography, it still comes down to being at the right place, at the right time, with the right equipment. Luckily, when your subject is the night sky, the right time and place can be precisely calculated. The procession of the sun, the phases of the moon, and the mathematical wandering of the planets across the backdrop of the cosmos have set time for nearly all of human history. I will explore the science and math behind some of my favorite photographs.

Patrick Cullis is a Boulder, Colorado-based photographer. He began photographing the night sky during a yearlong stint at the Amundsen-Scott South Pole research station in Antarctica, and has since photographed numerous astronomical phenomena across the country. He particularly enjoys photographing iconic Colorado landscapes at night, including his hometown Flatirons and the Maroon Bells outside of Aspen. Many of his photographs are planned weeks, months, or years in advance, taking in to account the location of planets and constellations, the position and phase of the moon, and always with an eye on the cloud forecast. His experience launching instruments to measure the formation of the Antarctic Ozone Hole also led to experiments with high altitude photography, sending his cameras to over 100,000 feet, most recently during the 2017 Great American Eclipse.

Science on Tap is a monthly opportunity for science enthusiasts and beer lovers to come together and discover the latest and greatest research in science and technology that is happening right here on the Front Range. Presented by Gunbarrel Brewing Company, local scientists across a variety of disciplines present their work in a fun, informal, and interactive setting while enjoying some of Boulder’s finest craft beers. You can expect plenty of beer to be flowing, a 30-40 minute presentation with intermission followed by discussion and Q&A.
