[KPNO 4m/90"]

About this image

Ruddy in the fading evening twilight, these domes at Kitt Peak approach the time to start another night's work (1974). Visible are the Lunar and Planetary Laboratory SpaceWatch domes, the University of Arizona's Steward Observatory 90-inch, and the Kitt Peak National Observatory's Mayall 4-meter telescope (left to right).
