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's BTA-6,
and was only truly outclassed by the Keck Observatory in the 1990s.
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 shaped from
a "blank" 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 reflector.
Among the telescope's current instruments:
In development:
- NGPS - Next Generation Palomar Spectrograph (aims to replace DBSP).
- SIGHT - Sharpening Images Using Guidestar at Hale Telescope (AO system).
Some instruments listed in the past:
- SDC - Stellar double coronagraph.
- LFC - Large Format Camera.
- Project 1640 aka P1640 - coronagraph.
- COSMIC - Carnegie Observatories Spectroscopic Multislit and Imaging Camera.
- Oxford SWIFT - integral field spectrograph.
- Four-shooter aka 4-shooter - wide-field spectrograph/camera.
- PFUEI - Prime Focus Universal Extragalactic Instrument (spectrograph/camera).
