The Canada-France-Hawaii telescope.
Abstract
The general concepts and technical details of the Canada-France-Hawaii telescope, located at an elevation of 4200 m in Mauna Kea on the island of Hawaii, are presented. The telescope is 3.5 m in diameter and uses the classical parabolic/hyperbolic combination, with polar type equatorial mounts. The focal plane instrumentation comprises more than 25 instruments and detectors, including a coude spectrograph f/7.4, an echelle coude spectrograph f/3.7, and Cassegrain focus instruments with aperture ratios of f/8 and f/35. Diagrams of several of these systems are presented. The first scientific results using the telescope show that excellent seeing conditions of less than one second of arc and a high resolution of the prime focus are obtained.
