celestron

Celestron is a company that makes telescopes, binoculars, spotting scopes, microscopes, and accessories for their products.The company (law)company was US owned until April 2005 when it was acquired by SW Technology Corporation, a Delaware company and affiliate of Synta Technology Corporation in China. Synta is a leading manufacturer of astronomy equipment that are copies of original designs by companies such as Celestron and Vixen (telescopes)Vixen.Celestron had struggled to remain profitable in an aggressive but limited market, in particular following protracted legal disputes with its US competitor Meade. The change of ownership was generally considered a good move in the amateur astronomy community as it provides Celestron with much needed capital to meet expansion and research and development costs. This is important to ensure Meade have a viable rival to stimulate innovation.Celestron was the first commerical manufacturer of the Schmidt-Cassegrain telescope telescope, introducing its "C-8" 8-inch telescope in the mid-1960s. The telescope, with its trademark matte orange tube (changed to glossy black in 1980), has been a popular large aperture, long-focal length telescope in a shortened optical tube. This design allows for easier transport than an equivalent Newtonian reflector telescope.The "C-8" was followed by the "C-5", "C-11", and "C-14" in the 1970s -- well before Meade started producing Schmidt-Cassegrain telescopeSCTs larger than 10 inches in the mid-1990s. Meade used to produce a 4inch" Schmidt-Cassegrain, but has since gone to Maksutov-Cassegrain designs in their smaller ETX style telescopes.A "C-925" was introduced in the late 1990s, as an intermediate-sized scope when Meade started producing 12, 14, and 16-inch SCTs. The largest production telescope produced by Celestron is the "C-20" observatory class photographic astrographAstrograph telescope introduced in 2004 (based on a corrected Dall-Kirkham telescopeDall-Kirkham design).In 2005, Celestron started selling its products through the American Imaginova Corporation's Orion Telescope & Binoculars (not to be confused with Orion_OpticsOrion Optics in the United Kingdom) using both the Celestron brand as well as optical tube assemblies rebadged with the Orion Telescope logo on Orion Telescope's equatorial mounts and accessories. It also introduced a "C-6" Schmidt-Cassegrain mounted on a German equatorial mount. It also introduced its own computerized alignment SCTs (in 8, 9.25, and 11-inches), known as "SkyAlign," in competition to Meade's "Level North Technology" (LNT) LX-90 scopes.As part of its collaboration with Imaginova, Celestron assisted in producing an Orion version of its 12-inch Dobsonian telescope, using BAK-7 optical glass mirrors instead of pyrex. BAK-7 glass is used primarily in binocular prisms, and has superior temperature expansion control than the more conventional pyrex glass.Celestron produces a range of 2.4 to 6-inch refractor telescopes, 6 to 10-inch traditional Newtonian reflectorreflector telescopes, the "C-90" and "C-120" Maksutov telescopeMaksutov-Cassegrain spotting scopes and a range of 6 to 12-inch Dobsonian telescopes known as the "Starhopper" series. Celestron also produce a number of introductory telescopes, one of which is a design copied from the famous "Astroscan" reflector telescope produced by the former New Jersey-based Edmund Scientific Corporation.
