Mount Wilson (California) a new Mt. Wilson Hotel. In 1908 a 60-inch (1524 mm) telescope was completed at the summit, and in 1910 the Solar Tower was erected. In 1913 the hotel burned down and was replaced by a second hotel that lasted until its demolition in 1966. The Toll Road opened to automobiles in 1912 and lasted until 1936. In 1917, the 100-inch Hooker Telescope was completed and saw first light and would be the world's largest telescope until the opening of the 200-inch Hale Telescope at Palomar Observatory in 1948. In 1919, American astronomer Edwin Hubble arrived at Mt. Wilson and,
History of the telescope Cerenkov imaging telescopes have been built around the world including: the HEGRA (1987), STACEE (2001), HESS (2003), and MAGIC (2004). In 1868, Fizeau noted that the purpose of the arrangement of mirrors or glass lenses in a conventional telescope was simply to provide an approximation to a Fourier transform of the optical wave field entering the telescope. As this mathematical transformation was well understood and could be performed mathematically on paper, he noted that by using an array of small instruments it would be possible to measure the diameter of a star with the same precision as a single telescope
