The Hale Telescope is a 200-inch (5.1 m), f /3.3 reflecting telescope at the Palomar Observatory in California, US, named after astronomer George Ellery Hale. With funding from the Rockefeller Foundation, he orchestrated the planning, design, and construction of the observatory, but did not live to see its commissioning.
Many celestial phenomena can be seen at more than one wavelength. 1  Optical telescopes can be used on Earth and in space. An example of a huge optical telescope in space is the Hubble Space Telescope through which astronomers can look out across the Universe without the distortion of light by the Earth's atmosphere. The first optical telescope was created 400 years ago, while the other kinds of telescopes were invented in the 20th century.
