The 60 Inch Telescope

George Ellery Hale built the 60-inch telescope in 1908; it was the largest telescope in the world at the time. The telescope is multi-purpose, capable of providing different optical configurations for a variety of uses. Its mirror, cast in 1894 by the Saint-Gobain glassworks in France, was given to Hale by his father.
At present, the telescope is primarily used in the HK Project, which studies the chromospheric variability of lower main-sequence and cool evolved stars. The Atmospheric Compensation Experiment (ACE) operated from 1992 to 1995 and used adaptive optics to obtain close to diffraction-limited images of naked-eye objects.
The tour continues up the hill, past a large water tank, to a small dome.
