Additional Details:
Eighteen years ago a new kind of glass was developed which was almost impervious to heat. This made possible and feasible the building of a huge mirror and construction of a telescope twice the size of any in existence. Polished and perfected over a period of seven years at California Institute of Technology, Pasadena. the 200-inch mirror was installed on 1947 in the 10-story observatory on Mt. Palomar, 70 miles from San Diego. Open to the public, Reached over paved highway.
