Canada-France-Hawaii Telescope

Observatory in Mauna Kea

This 3.6m (11.8ft) optical/infrared telescope's first light was 1979, making it the oldest operational telescope on the mountain. It specializes in wide-field imaging, examining large structures like remote galaxies. The addition of the world's largest high-resolution spectropolarimeter allows observations of the magnetic fields around distant stars. The telescope also has operating agreements with China, Taiwan, and Brazil.
