The Dexter Southfield School includes the Clay Center for Science and Technology. The Clay Center Observatory is a unique facility at the Clay Center for Science and Technology dedicated to astronomical research and science education through its programs, instructional activities, and publications. The observatory is equipped with a custom-made, diffraction-limited 0.64-m (25-inch) f/9.6 Ritchey-Chrétien reflecting telescope, similar in optical design to the Hubble Space Telescope. The observatory is fully automated and can be operated remotely from any computer in the world via the Internet, thus serving as a valuable resource for astronomers around the world.
Nonprofit institutions including both public and independent schools and colleges worldwide are invited to use the facility and to collaborate with Dexter Southfield on educational programs and research projects.
