American astronomer George E. Hale (1868- 1938) successfully persuaded and was sponsored by Carnegie Institution in Washington, D.C., to make the telescope of Mount Wilson Observatory: the 60-inch (1.5m) telescope was built in 19654. These telescopes are very successful, which leads to a rapid increase in understanding of the cosmic scale of 1920s, and shows that dreamers like Haier need bigger telescopes to collect information.

1928, Haier received a $6 million grant from the Rockefeller Foundation, and built a 200-inch (5-meter) observatory with a 200-inch mirror under the management of the California Institute of Technology, which it co-founded. In the early 1960s, Haier chose Paloma Mountain in San Diego, California, which is 65,438+0,700 meters (5,600 feet) above sea level. It is the best place in the United States and will hardly be affected by the increasingly serious light pollution in urban centers such as Los Angeles. Corning Glass Factory was selected to make 200-inch (5-meter) lenses with new Pai Gex glass. From 1936, the observatory and the facilities under construction began to work, but due to the interruption of World War II, the telescope was not completed until 1948.

200-inch Haier telescope1started shooting on October 26th, 1949+65438. Under the guidance of American astronomer Haber, the goal is NGC 226 1, and the result was published in Collier magazine on May 7, 1949.

Every sunny night, astronomers from California Institute of Technology, Cornell University and Jet Propulsion Laboratory, as well as business partners, will use it for continuous research. It is equipped with modern optical and infrared array images, spectrometers and adaptive optical systems. It also uses a lucky cam and an optically driven lens, which makes its analytical ability close to the theoretical limit in the observation of some projects (see lucky image).
