For nearly 70 years, the Black Hills Astronomical Society (BHAS) has introduced thousands of area residents to the wonders of the night sky at the Hidden Valley Observatory just outside of Rapid City. Hank Fridell, BHAS member, will present a series of astronomy photos taken in the Black Hills and discuss how observing the night sky has changed over the years, and with it, our understanding of the universe. Attendees of this presentation will also discover how to obtain a free copy of the book chronicling the history of the BHAS, which was written during the pandemic by Fridell; Ron Dyvig, director of the Badlands Observatory in Quinn, SD; and Richard Walker, director of the Hidden Valley Observatory.
