Astronomy Club members learned about astrophotography and visual astronomy in a meeting on Oct. 18.
President Eric Dong (11) began by describing the most prominent objects in the night sky, including constellations, solar system planets and bright stars. He introduced various astrophotography instruments like astronomy binoculars and camera telescopes, demonstrating the use of an equatorial mount, a tool used to align a camera with the rotation of celestial bodies.
“Learning about the entire process behind visual astronomy was really enjoyable,” club member Isabelle Niu (10) said. “The presentation grew my interest in observational astronomy, especially since it introduced simple approaches for taking and processing astronomical images at home.”
Eric discussed image processing of low-contrast photos to enhance the visibility of stars in photos. He then showed photos of exterior galaxies and solar photography taken by physics teachers Chris Spenner and Mark Brada.
“I’m hoping that going forward, members continue to show interest in actually looking at things rather than just learning facts about astronomy,” club adviser Mark Brada said. “I have a couple of telescopes that I could set up for us. We would have to meet in a location outside of town, but it’s certainly doable.”
Astronomy Club teaches members theoretical astronomy in preparation for competitions like the USA Astronomy and Astrophysics Olympiad. Officers also give lectures about a variety of topics, from black hole physics to special relativity, educating members about the universe. The club hosts speaker events with experts in astronomy with opportunities for attendees to learn about specialized fields in collaboration with Space for Space, a nonprofit organization dedicated to global education about astronomy.
“Since our meetings are determined by popular interest, I really hope we can do some visual astronomy one day,” Eric said. “I’m sure they learned a lot about actually using telescopes and are eager to learn more. Maybe we can even do an outing one day.”
