1/26/1949 – Palomar Observatory’s Hale Telescope sees first light
On January 26, 1949, the 200-inch Hale Telescope saw first light at Palomar Observatory in San Diego County, California. The reflector was christened the Hale Telescope after astronomer George Ellery Hale, who lead the way in the planning, design, and construction of the 200″ telescope and the observatory that would encompass it. The project took a total of 20 years to complete due to a series of interruptions as a result of World War II. Sadly, Hale passed away before he could see the telescope commissioned.

Construction on the ambitious telescope began in 1928, after Hale received a 6 million dollar donation from the Rockefeller Foundation. At the time of its completion, the Hale Telescope was the largest telescope in the world and represented a breakthrough in stargazing technology, setting a precedent that would remain for another 30 years until the completion of the Soviet BTA-6 optical telescope in 1976.
The Hale Telescope is still in use by research astronomers at Palomar Observatory today.
