Astronomical Observatory: Kitt Peak National Observatory

Yale University astronomy professor Charles Bailyn gives a guided tour of the two research telescopes operated by the WIYN Consortium at the Kitt Peak National Observatory in Arizona. The first telescope is a 0.9m aperture telescope built in the 1960s; the second is the WIYN 3.5m new technology telescope commissioned in 1994. The tour emphasizes the ways in which new technology has improved the quality of ground-based telescopes.
