Hale Telescope

(5.1 m reflector telescope in California)

Hale Telescope is a 5.1 m (200 inch) reflector telescope at Palomar Observatory. It began operation in 1949 and was the largest reflecting telescope until 1976 when the BTA-6 was built. It is named for George Ellery Hale who orchestrated its construction.

The telescope has an equatorial mount, using a Serrurier truss, a design that maintains optical alignment despite gravity. The mirror is a glass (Pyrex) monolithic mirror made by Corning Glass Works. Depending upon the particular instrument's mounting, the telescope functions as a Cassegrain reflector, a prime focus reflector, or a coudé focus telescope reflector. Among the telescope's current instruments:
