Bradley Observatory

The Bradley Observatory (84 17 38.98 W, 33 45 54.84 N) is an astronomical teaching and research facility located on the campus of Agnes Scott College in Decatur, Georgia. The Observatory, named in honor of William C. and Sarah Hall Bradley, contains the 70-seat Delafield Planetarium and a 100-seat capacity lecture hall.

The building also contains a library/seminar room, two faculty offices, a darkroom, a student computer lab, and an observing plaza for astronomical viewing. The large dome atop the Observatory houses the 30-inch Lewis H. Beck telescope.

Bradley Observatory Celebrated 65 Years in 2015!

Observatory Visitor Fees and Policies 

Bradley Observatory Group Tour

Bradley Observatory at Agnes Scott College is closed due to the COVID-19 pandemic. We are in the process of making a series of short video tours of the Observatory and Beck Telescope. We also are going to make available a series of short "planetarium" videos that will address particular topics for particular ages. All of these videos will be available (accessible from this site) by the end of the month, and we will add more as they are completed. In the meantime, we hope that you all are staying safe and well, and we look forward to seeing you again in person as soon as possible.
