Richard Herr 24 Inch Telescope
MCAO was constructed in the early 1960s. The observatory houses a 24 inch (0.6m) Tinsley telescope. The telescope is the main research instrument, studying everything from asteroids to flare stars to pulsating white dwarfs during its lifetime. In 2000, the 24 inch received its first advanced digital camera. The new camera revitalized scientific research at MCAO.
