Optical telescope - Wikipedia, the free encyclopedia The size of optical telescopes increased steadily in the 20th century, doubling between the 1910s and the 1940s, and doubling again between the late 1940s and the 1990s. Wide-field telescopes are used to track satellites and asteroids, for cosmic-ray research, and for surveys of the sky. An optical telescope is a telescope which is used to gather, and focus light, for directly viewing a magnified image, making a photograph, etc. The term is used especially for a monocular with static mounting for observing the sky. en.wikipedia.org /wiki/Optical_telescope   (1010 words)

Optical Astronomy The SOAR telescope is a Project for a 4.2-meter aperture telescope funded by a partnership between the USA National Optical Astronomy Observatories (NOAO), the Country of Brazil, Michigan State University, and the University of North Carolina at Chapel Hill. The Vainu Bappu Observatory (VBO) is the main optical observatory of the Indian Institute of Astrophysics (IIA), and is located in the picturesque neighbourhood of the village of Kavalur in the state of Tamil Nadu.

Bill Keel's Telescope Life List - Bolshoi Teleskop Azimultanyi Up to this time optical telescopes have primarily used equatorial mountings, in which one of the axes of the telescope was in the direction of the Earth's pole, parallel to the axis of Earth's rotation. The telescope is situated at an altitude of 2,070 meters (6,800 feet) on the northern slopes of the Caucasus Mountains. The telescope uses an f/4 primary mirror (giving a 26-meter tube housed in a dome 58 meters high), with instruments located in an expansive prime-focus housing or at one of the Nasmyth foci on either side of the fork mount (one of the spectrographs has a collimator 2 meters across). www.astr.ua.edu /keel/telescopes/bta.html   (3860 words)

MSN Encarta - Telescope Many telescopes are Earth-based, located in astronomical observatories around the world. In 2001 the European Southern Observatory opened the largest optical interferometer, the Very Large Telescope (VLT), in the Atacama Desert in northern Chile. Telescopes are the fundamental research instruments that enable astronomers to tackle scientific questions about the birth of the universe ( see Big Bang Theory ; Cosmology); the emergence of structure in the early universe; the formation and evolution of stars, galaxies, and planetary systems; and the conditions for the emergence of life itself. encarta.msn.com /encyclopedia_761557777/Telescope.html   (59 words)

Very Large Telescope - Freepedia In its full interferometric operating mode, the four telescopes provide the same light gathering ability as a single 16m telescope, making it the largest optical telescope in the world. The VLT consists of a cluster of four large telescopes, and an interferometer (VLTI) which will be used to resolve fine features. The telescopes have been named after the names of some astronomical objects in the local Mapuche language: Antu (The Sun), Kueyen (The Moon), Melipal (The Southern Cross), and Yepun (Venus) en.freepedia.org /VLT.html   (265 words)

Hobby-Eberly Telescope A fixed elevation-axis design, based on the radio telescope at Arecibo, and an innovative system for tracking stars, contributed to an 80% reduction in initial costs compared to optical telescopes of similar size.

The Trimester reports are prepared by the HET Lead RA and include information about the seeing, weather, allocation of observations by partner, distribution of objects and status of the equipment. www.as.utexas.edu /mcdonald/het/het.html   (319 words)

binoc.html When the word "telescope" is used, most people identify it with just one kind of telescope: an optical telescope that is used to collect visible light as seen by our eyes. Most of these telescopes are housed in observatories or are in space. Most people don't realize that the views they see through a telescope are not like the photographs they've seen all their lives of the planets, galaxies, star clusters, etc. Instead, except for the moon and the bright planets, most everything else looks dim and small through the eyepiece of a telescope. darkskyinstitute.org /binoc.html   (1062 words)

Group 70 Group 70 is a non-profit educational organization comprised of people from many countries all around the world and many walks of life seeking to make the beauty of astronomy available to the peoples of the world. They began in 1988 with the goal of building a large amateur telescope, a 70 inch (1.8 m) astronomical instrument. Upon completion it would be the largest telescope in the world built by and for those who do not have access to large institution-run observatories. www.worldhistory.com /wiki/G/Group-70.htm   (193 words)

Bill Keel's Telescope Life List Since astrophysics now has (and needs) access to much of the electromagnetic spectrum, there are optical, infrared, radio, ultraviolet, and X-ray facilities to be found. To show what kinds of projects can be done with various instruments (at least the kinds I've thought of), here's a gallery of observatories and telescopes I've used with some sample data and results. Some images are still to be added, and all the listed sites will eventually have their own information and image pages. www.astr.ua.edu /keel/telescopes   (368 words)

Reflecting telescope - Wikipedia, the free encyclopedia On smaller telescopes, and camera lenses, the secondary is often mounted on an optically-flat, optically-clear glass plate that closes the telescope tube. Their optical performance comes from the use of a spherical mirror which reintroduces the spherical and field curvature aberrations, but avoids all the others. Thirty inch Schmidt-Cassegrains are used for sky surveys at astronomical observatories and satellite tracking stations. en.wikipedia.org /wiki/Reflecting_telescope   (2041 words)
