Canada-France-Hawaii Telescope
The Canada-France-Hawaii Telescope (CFHT) is a large telescope operated jointly by the National Research Council of Canada , the Center national de la recherche scientifique (CNRS) in France and the University of Hawaii with a primary mirror diameter of 3.58 m located near the summit of the extinct Mauna Kea volcano in Hawaii at an altitude of 4204 m. The telescope has been used in scientific operations since 1979.
Like the famous Mount Palomar telescope, the CFHT is a classic primary focus / Cassegrain telescope with a parabolic ground primary mirror. The recording devices are a large-field camera with a high-resolution CCD mosaic of 36 individual CCDs with 2048 × 4612 pixels each, an infrared detector and a large-field infrared camera, a system for adaptive optics and various spectrographs .
Some of the main research areas of CFHT are or were:
- A sky survey (Canada-France-Hawaii Telescope Legacy Survey, CFHTLS), which is carried out in an observation campaign over 5 years with a total of 450 observation nights.
- Exploring extremely distant galaxies and the large-scale structure of the universe .
- Exploration of small asteroids and moons of the solar system , such as the new Jupiter moons and the Kuiper belt object consisting of two parts, 1998 WW 31 .
- Creation of the Gaia Ecliptic Pole Catalog (GEPC), which was used for the calibration of the Gaia mission .
