RC Optical Systems
RC Optical Systems was a high-end American telescope and optics manufacturer that specialized in Ritchey-Chrétien telescopes with hyperbolic mirrors. RC also made related mounts and systems for the telescopes, with a focus on open and closed carbon fiber trusses for low expansion. The basic Ritchey-Chrétien optical system uses two mirrors and no refracting elements, which reduces light loss and its optical characteristics make it popular for astrophotography. Refracting elements may be added to correct for field curvature. RC Optical Systems was started 1998 and was located in Flagstaff, Arizona. Telescopes and systems were sold commercially to individuals, institutions, and governments. The smallest RCOS telescope, the 12.5 inch F/9 Ritchey-Chrétien had a base price of just over twenty thousand US dollars in 2009, with large and/or custom models costing considerably more. RC Optical Systems and Star Instruments won a lawsuit in 2008 against Meade Instruments over Meade ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

TacSat-2
TacSat-2 is the first in a series of U.S. military experimental technology and communication satellites.TacSat-2 (also known as JWS-D1 ((Joint Warfighting Space-Demonstrator 1) or RoadRunner) was an experimental satellite built by the USAF's Air Force Research Laboratory with an operational life expected to be not more than one year as part of the "Advanced Concept Technology Demonstration" program. Purpose The TacSat series of experimental spacecraft are designed to allow military commanders on a battlefield to request and obtain imagery and other data from a satellite as it passes overhead. Collected data will be delivered to field commanders in minutes rather than hours or days. The sensor on TacSat-2 could collect color images sharp enough to distinguish ground objects as small as 1 meter in diameter. Systems Satellites in the TacSat series were planned to use commercial or available launchers, and largely off-the-shelf components, in order to reduce costs. Satellite ...

Astrophotography
Astrophotography, also known as astronomical imaging, is the photography or imaging of astronomical objects, celestial events, or areas of the night sky. The first photograph of an astronomical object (the Moon) was taken in 1840, but it was not until the late 19th century that advances in technology allowed for detailed stellar photography. Besides being able to record the details of extended objects such as the Moon, Sun, and planets, modern astrophotography has the ability to image objects invisible to the human eye such as dim stars, nebulae, and galaxies. This is done by long time exposure since both film and digital cameras can accumulate and sum photons over these long periods of time. Photography using extended exposure-times revolutionized the field of professional astronomical research, recording hundreds of thousands of new stars, and nebulae invisible to the human eye. Specialized and ever-larger optical telescopes were constructed as essentially big cameras to reco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

University Of Central Florida
The University of Central Florida (UCF) is a public research university whose main campus is in unincorporated Orange County, Florida. UCF also has nine smaller regional campuses throughout central Florida. It is part of the State University System of Florida. With 70,406 students as of the Fall 2021 semester, UCF has the second-largest student body of any public university in the United States. UCF was founded in 1963 and opened in 1968 as Florida Technological University, with the mission to provide personnel to support the growing U.S. space program at the Kennedy Space Center and Cape Canaveral Space Force Station on Florida's Space Coast. As its academic scope expanded beyond engineering and technology, Florida Tech was renamed the University of Central Florida in 1978. UCF's space roots continue, as it leads the NASA Florida Space Grant Consortium.

Robinson Observatory
The Robinson Observatory is an astronomical observatory owned and operated by the University of Central Florida College of Sciences in Orlando, Florida, USA. Public viewings are held the first and third Wednesday of each month and are sponsored by the Central Florida Astronomical Society (CFAS). History The observatory was built at a cost of over $500,000 in 1995, with Herbert Robinson donating almost half of the total cost. The observatory was given the name Robinson posthumously, eight months after Herbert Robinson's death, on April 25, 1996. In the 2000s, a number of updates and renovations were completed at the observatory. The most recent addition was in 2007; it included high speed internet, a new Ritchey-Chrétien telescope, and the ability to remotely operate the telescope and dome. Future Plans are under way to expand the Robinson Observatory to include two smaller telescopes with domes donated by the United States Air Force. See also *List of astronomica ...

Chile
Chile, officially the Republic of Chile, is a country in the western part of South America. It is the southernmost country in the world, and the closest to Antarctica, occupying a long and narrow strip of land between the Andes to the east and the Pacific Ocean to the west. Chile covers an area of , with a population of 17.5 million as of 2017.

CTIO
The Cerro Tololo Inter-American Observatory (CTIO) is an astronomical observatory located on Cerro Tololo in the Coquimbo Region of northern Chile, with additional facilities located on Cerro Pachón about to the southeast. It is approximately east of La Serena, where support facilities are located. The site was identified by a team of scientists from Chile and the United States in 1959, and it was selected in 1962. Construction began in 1963 and regular astronomical observations commenced in 1965. Construction of large buildings on Cerro Tololo ended with the completion of the Víctor Blanco Telescope in 1974, but smaller facilities have been built since then. Cerro Pachón is still under development, with two large telescopes (Gemini South and SOAR) inaugurated since 2000, and one in the early stages of construction (the Vera C. Rubin Observatory) The principal telescopes at CTIO are the 4 m Víctor M. Blanco Telescope, named after Puerto Rican astronomer Víctor Man ...

University Of North Carolina At Chapel Hill
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The unive ...

PROMPT (telescope)
PROMPT, an acronym for Panchromatic Robotic Optical Monitoring and Polarimetry Telescopes, is being built by the University of North Carolina at Chapel Hill at Cerro Tololo Inter-American Observatory (CTIO) in Chile. PROMPT's primary objective is rapid and simultaneous multiwavelength observations of gamma-ray burst afterglows, some when they are only tens of seconds old. In addition to measuring redshifts by dropout, and early-time SFDs and extinction curves of sufficiently bright afterglows in unprecedented detail, PROMPT will facilitate quick response observations at larger observatories such as the UNC-led 4.1-m SOAR Telescope. PROMPT will also serve as a platform for undergraduate and high school education throughout the State of North Carolina. PROMPT consists of six 0.41-m Ritchey-Chrétien telescopes by RC Optical Systems on rapidly slewing (9°/sec) Paramount ME mounts by Software Bisque, each under a clamshell dome by Astro Haven. Five of these telescopes use rapid-rea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
