This 200-inch telescope is named after astronomer George Ellery Hale. It was built by a Caltech-Carnegie consortium using a Pyrex blank manufactured by Corning Glass Works. The telescope (the largest in the world at that time) saw 'first light' in 1949.
The Hale Telescope is operated by a consortium of Caltech, Jet Propulsion Laboratory, and Cornell University. [1]
The Palomar Observatory Sky Survey (POSS), sponsored by the National Geographic institute, was completed in 1954 (actual date referenced varies, ranging from 1950 to 1957). This survey was performed using (14 inch)² or (6 degree)² photographic plates in both blue and red (separately) on the 48-inch Schmidt reflecting telescope. The survey covered the sky from a declination of +90 degrees (celestial north pole) to -24 degrees (plate centers) and all right ascensions and had a sensitivity to +22 magnitudes.
Until the completion of the Two Micron All Sky Survey (2MASS), POSS was the most extensive all-sky survey ever. When completed, the Sloan Digital Sky Survey will surpass both. POSS also exists in digitized form (i.e., the photographic plates were scanned), as the Digital Sky Survey (DSS) [1].
One of the current ongoing research programs at Palomar is the Near-Earth Asteroid Tracking program. The Hale Telescope
