  Location of Canada–France–Hawaii Telescope | |
The Canada–France–Hawaii Telescope (CFHT) is located near the summit of Mauna Kea mountain on Hawaii's Big Island at an altitude of 4,204 meters (13,793 feet), and is one of the observatories that comprise the Mauna Kea Observatories. Operational since 1979,[1] the telescope is a Prime Focus/Cassegrain configuration with a usable aperture diameter of 3.58 metres (11.7 ft).
The corporation is bound by a tripartite agreement between the University of Hawaii, the National Research Council (NRC) in Canada and the Centre National de la Recherche Scientifique (CNRS) in France. CFHT also has partnerships with the National Astronomical Observatory of China (NAOC), the Academia Sinica Institute of Astronomy and Astrophysics (ASIAA) in Taiwan, the Laboratório Nacional de Astrofisica (LNA) in Brazil and the Korea Astronomy and Space Science Institute (KASI) in Korea. The contributions from these associate partners help fund CFHT's future instrumentation. Currently, CFHT observing time is offered to scientists from all the seven countries in the partnership. Astronomers from the European Union can also submit proposals through the Optical Infrared Coordination Network for Astronomy (OPTICON) access program.
CFHT currently operates four instruments:
- MegaCam,[2] a one square degree field high-resolution CCD mosaic of 40 CCDs totalling 378 megapixels.
- WIRCam,[3] an infrared mosaic of 4 detectors totalling 16 megapixels, optimized for the J, H, and K spectral bands.[4]
- ESPaDOnS,[5] an echelle spectrograph/spectropolarimeter.
- SITELLE, a wide-field Fourier transform spectrograph[6]
Future instrumentation planned for CFHT includes SPIRou, a near-infrared spectropolarimeter.
CFHT, in collaboration with Coelum Astronomia, maintains a public-outreach website called "Hawaiian Starlight"[7] which offers extremely high-quality versions of CFHT images in various formats including a yearly calendar.
