Five United States Naval Observatory astronomers were interviewed about their observing techniques on various telescopes used at the observatory. The sessions documented both classical visual techniques for star observation, as well as computer controlled telescopes and electronic detection techniques that have virtually replaced the eye in modern astronomical research. Interviews took place in various telescope domes on the USNO grounds, Washington, DC and were with Thomas E. Corbin, Geoffrey Douglass, F. Stephen Gauss, Dennis Dean McCarthy, and Charles Worley.
