Where is the Hale Telescope located?
Palomar Observatory
Hale Telescope, in full George Ellery Hale Telescope, one of the world’s largest and most powerful reflecting telescopes, located at the Palomar Observatory, Mount Palomar, Calif.
Is the Hale Telescope open to the public?
Please note that the interior of the Hale Telescope dome is kept at nighttime temperatures for an elevation of 5,598 feet/1,702 meters. Dress accordingly. Please see our tours page for information about guided tours. We do not offer guided tours every day that the Observatory is open to the public.
Why is it called the 200 inch telescope?
The Hale Telescope is a 200-inch (5.1 m), f/3.3 reflecting telescope at the Palomar Observatory in San Diego County, California, US, named after astronomer George Ellery Hale. The Hale Telescope represented the technological limit in building large optical telescopes for over 30 years.
Is the Hale Telescope still used?
It was completed in 1949 and is still in active use. The Hale Telescope represented the technological limit in building large optical telescopes for over 30 years.
What type of telescope is the Palomar?
reflecting telescope
The Hale Telescope is a 200-inch (5.1 m), f/3.3 reflecting telescope at the Palomar Observatory in San Diego County, California, US, named after astronomer George Ellery Hale.
How big is the Hale Telescope?
200-inch
The 200-inch (5.1 m) Hale Telescope (f/3.3) was the world’s largest effective telescope for 45 years (1948-1993). It is still a workhorse of modern astronomy. It is used nightly for a wide range of astronomical studies.
Who built the Hale Telescope?
founder George Ellery Hale
This extraordinary instrument was the vision of astronomer and Caltech founder George Ellery Hale—the man behind the largest telescopes in the world at the beginning of the 20th century.
Where is the Hale telescope located?
The Hale Telescope is a 200-inch (5.1 m), f /3.3 reflecting telescope at the Palomar Observatory in San Diego County, California, US, named after astronomer George Ellery Hale.
What was the first telescope built at Mount Wilson?
Hale supervised the building of the telescopes at the Mount Wilson Observatory with grants from the Carnegie Institution of Washington: the 60-inch (1.5 m) telescope in 1908 and the 100-inch (2.5 m) telescope in 1917.
What was the last telescope to have a parabolic mirror?
The Mount Palomar Hale Telescope turned out to be the last world-leading telescope to have a parabolic primary mirror.
What is the size of Hale’s mirror?
The Hale’s 200 in (510 cm) mirror was near the technological limit of a primary mirror made of a single rigid piece of glass. Using a monolithic mirror much larger than the 5-meter Hale or 6-meter BTA-6 is prohibitively expensive due to the cost of both the mirror, and the massive structure needed to support it.
