Hale Telescope (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Hale Telescope is a 200-inch (5.1 m), f/3.3 reflecting telescope at the Palomar Observatory in California, named after astronomer George Ellery Hale, who with funding from the Rockefeller Foundation orchestrated the planning, design, and construction of the observatory, but did not live to see its commissioning. The Hale was ground breaking for its time, with double the aperture of the next largest telescope and pioneering the use of many technologies such as vapor deposited aluminum and low thermal expansion glass.
