Telescopes and Modern Observatories

A telescope is an optical instrument that gathers and focuses light into a camera, CCD, spectrograph, or an astronomer’s eye. Two major types of telescopes dominate astronomy: reflectors and refractors. Many of the world’s largest telescopes are housed at observatories: The entire complex of buildings, telescopes, equipment, and staff involving scientific astronomical observations. Small observatories might consist of just one telescope situated in a dome, one instrument and computer, and one observer. McDonald Observatory is an example of a major observatory, and consists of five major telescope in five different domes, numerous instruments, computers, living quarters, outbuildings, astronomers, and engineers.
