Slooh
Slooh is a robotic telescope service that can be viewed live through a web browser. It was not the first robotic telescope, but it was the first that offered "live" viewing through a telescope via the web. Other online telescopes traditionally email a picture to the recipient. The site has a patent on their live image processing method. Slooh is an online astronomy platform with live-views and telescope rental for a fee. Observations come from a global network of telescopes located in places including Spain and Chile. The name Slooh comes from the word " slew" to indicate the movement of a telescope, modified with "ooh" to express pleasure and surprise. History The service was founded in 2002 by Michael Paolucci. As of October 2009, Paolucci remains as chairman. The service went online December 25, 2003 but was not available to the public until 2004. Participating observatories The original astronomical observatory is located on the island Tenerife in the Canary Islands on t ...

Robotic Telescope
A robotic telescope is an astronomical telescope and detector system that makes observations without the intervention of a human. In astronomical disciplines, a telescope qualifies as robotic if it makes those observations without being operated by a human, even if a human has to initiate the observations at the beginning of the night or end them in the morning. It may have software agents using artificial intelligence that assist in various ways such as automatic scheduling. A robotic telescope is distinct from a remote telescope, though an instrument can be both robotic and remote. By 2004, robotic observations accounted for an overwhelming percentage of the published scientific information on asteroid orbits and discoveries, variable star studies, supernova light curves and discoveries, comet orbits and gravitational microlensing observations. All early phase gamma ray burst observations were carried by robotic telescopes. Design Robotic telescopes are complex systems that ...

Logo
A logo (abbreviation of logotype; ) is a graphic mark, emblem, or symbol used to aid and promote public identification and recognition. It may be of an abstract or figurative design or include the text of the name it represents as in a wordmark. In the days of hot metal typesetting, a logotype was one word cast as a single piece of type (e.g. "The" in ATF Garamond), as opposed to a Typographic ligature, ligature, which is two or more letters joined, but not forming a word. By extension, the term was also used for a uniquely set and arranged typeface or colophon (publishing), colophon. At the level of mass communication and in common usage, a company's logo is today often synonymous with its trademark or brand.Wheeler, Alina. ''Designing Brand Identity'' © 2006 John Wiley & Sons, Inc. (page 4) Etymology Online Etymology Dictionary, Douglas Harper's Online Etymology Dictionary states that the term 'logo' used in 1937 "probably a shortening of logogram". History Numerous inv ...

Domes
A dome () is an architectural element similar to the hollow upper half of a sphere. There is significant overlap with the term cupola, which may also refer to a dome or a structure on top of a dome. The precise definition of a dome has been a matter of controversy and there are a wide variety of forms and specialized terms to describe them. A dome can rest directly upon a rotunda wall, a drum, or a system of squinches or pendentives used to accommodate the transition in shape from a rectangular or square space to the round or polygonal base of the dome. The dome's apex may be closed or may be open in the form of an oculus, which may itself be covered with a roof lantern and cupola. Domes have a long architectural lineage that extends back into prehistory. Domes were built in ancient Mesopotamia, and they have been found in Persian, Hellenistic, Roman, and Chinese architecture in the ancient world, as well as among a number of indigenous building traditions throughout the worl ...

La Dehesa
La Dehesa is a suburban neighborhood in Lo Barnechea Commune of Santiago, Chile. It borders Las Condes to the south and Vitacura to the west. It is located in a valley near the Andes, in the northeast of the city, north of the Mapocho River. La Dehesa is known as one of Chile's most affluent neighborhoods. History It is believed that the first human group to be discovered here were mainly hunter–gatherer nomads. They came in search of guanacos; they arrived in Santiago in approximately 10,000 BC. Around the year 800 BC, the area became inhabited along the shores of the Mapocho River, representing the first sedentary population, which resulted from the establishment of farming communities and the lamini's domestication. The area was controlled by the Inca and by the Spanish during the seventeenth century. The Spanish were still in control of the area in the early 1800s when Bernardo O'Higgins helped to win its independence from that empire in 1810. In 1964 there was discove ...

Refractor
A refracting telescope (also called a refractor) is a type of optical telescope that uses a lens (optics), lens as its objective (optics), objective to form an image (also referred to a dioptrics, dioptric telescope). The refracting telescope design was originally used in spyglasses and astronomy, astronomical telescopes but is also used for long-focus lens, long-focus camera lenses. Although large refracting telescopes were very popular in the second half of the 19th century, for most research purposes, the refracting telescope has been superseded by the reflecting telescope, which allows larger apertures. A refractor's magnification is calculated by dividing the focal length of the objective lens by that of the eyepiece. Refracting telescopes typically have a lens at the front, then a optical train, long tube, then an eyepiece or instrumentation at the rear, where the telescope view comes to focus. Originally, telescopes had an objective of one element, but a century later, tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apochromat
An apochromat, or apochromatic lens (apo), is a photographic or other lens that has better correction of chromatic and spherical aberration than the much more common achromat lenses. Explanation Chromatic aberration is the phenomenon of different colors focusing at different distances from a lens. In photography, chromatic aberration produces soft overall images, and color fringing at high-contrast edges, like an edge between black and white. Astronomers face similar problems, particularly with telescopes that use lenses rather than mirrors. ''Achromatic'' lenses are corrected to bring ''two'' wavelengths into focus in the same plane – typically red (~0.590 µm) and blue (~0.495 µm). ''Apo''chromatic lenses are designed to bring ''three'' colors into focus in the same plane – typically red (~0.620 µm), green (~0.530 µm), and blue (~0.465 µm). The residual color error (secondary spectrum) can be up to an order of magnitude less than for an achro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telephoto Lens
A telephoto lens, in photography and cinematography, is a specific type of a long-focus lens in which the physical length of the lens is shorter than the focal length. This is achieved by incorporating a special lens group known as a ''telephoto group'' that extends the light path to create a long-focus lens in a much shorter overall design. The angle of view and other effects of long-focus lenses are the same for telephoto lenses of the same specified focal length. Long-focal-length lenses are often informally referred to as ''telephoto lenses'', although this is technically incorrect: a telephoto lens specifically incorporates the telephoto group. Telephoto lenses are sometimes broken into the further sub-types of short telephoto (85–135 mm in 35 mm film format), medium telephoto: (135–300 mm in 35 mm film format) and super telephoto (over 300 mm in 35 mm film format) . Construction In contrast to a telephoto lens, for any given focal len ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Celestron
Celestron is an American company based in Torrance, California, United States, that manufactures telescopes and distributes telescopes, binoculars, spotting scopes, microscopes, and accessories manufactured by its parent company, the Synta Technology Corporation of Taiwan. History The predecessor of Celestron was Valor Electronics, an electronics and military components firm founded in 1955 by Tom Johnson. Johnson became involved with telescopes when he built a 6" reflecting telescope for his two sons. In 1960, Johnson established the "Astro-Optical" division of Valor, which would later become Celestron. By 1964, Johnson had founded "Celestron Pacific" as a division of Valor Electronics offering Schmidt-Cassegrain telescopes from 4" to 22". In 1970 Celestron introduced its "C8" 8" diameter 2032 mm focal length, ƒ10 telescope, the first of a new line of telescopes built using methods developed by Celestron to produce Schmidt-Cassegrains at a high volume and low cost. These m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deep Sky Objects
A deep-sky object (DSO) is any astronomical object that is not an individual star or Solar System object (such as Sun, Moon, planet, comet, etc.). The classification is used for the most part by amateur astronomers to denote visually observed faint naked eye and telescopic objects such as star clusters, nebulae and galaxies. This distinction is practical and technical, implying a variety of instruments and techniques appropriate to observation, and does not distinguish the nature of the object itself. Origins and classification Classifying non-stellar astronomical objects began soon after the invention of the telescope. One of the earliest comprehensive lists was Charles Messier's 1774 Messier catalog, which included 103 "''nebulae''" and other faint fuzzy objects he considered a nuisance since they could be mistaken for comets, the objects he was actually searching for. As telescopes improved these faint nebulae would be broken into more descriptive scientific classificati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
