Telescopes
- A 1.32 m (52 in) reflecting telescope was built by Tinsley Laboratories in 1969 and installed at PLO the same year.[1] In 1975 it was moved to Kitt Peak National Observatory near Tucson, Arizona, where it is now known as the McGraw-Hill Telescope.[2][3]
- The 0.92 m (36 in) Heber Doust Curtis Telescope is a Schmidt camera that began operating at PLO in 1950.[1] It was moved to the Cerro Tololo Inter-American Observatory in Chile in 1967, where it is referred to as the Curtis Schmidt Telescope.[4]
