Table Mountain Observatory
Table Mountain Observatory (TMO) is an Observatory, astronomical observation facility operated by NASA's Jet Propulsion Laboratory (California Institute of Technology). It is located in Big Pines, California, in the Angeles National Forest near Wrightwood, California, Wrightwood, north-northeast of Los Angeles, California. TMO is part of JPL's Table Mountain Facility (TMF). The larger site hosts a number of non-astronomical projects. The site was first used by the Smithsonian Institution in 1924, which conducted atmospheric, solar, and astronomical observations for many years. JPL took over the lease in 1962. The observatory conducts high-precision astrometric observations to support NASA and international spacecraft mission navigation, confirmation and recovery of near-Earth objects such as comets and asteroids that may potentially impact the Earth, and technology development. The main-belt asteroid 84882 Table Mountain was named in honor of the observatory. List of discovered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Minor Planet Center
The Minor Planet Center (MPC) is the official body for observing and reporting on minor planets under the auspices of the International Astronomical Union (IAU). Founded in 1947, it operates at the Smithsonian Astrophysical Observatory. Function The Minor Planet Center is the official worldwide organization in charge of collecting observational data for minor planets (such as asteroids), calculating their orbits and publishing this information via the '' Minor Planet Circulars''. Under the auspices of the International Astronomical Union (IAU), it operates at the Smithsonian Astrophysical Observatory, which is part of the Center for Astrophysics along with the Harvard College Observatory. The MPC runs a number of free online services for observers to assist them in observing minor planets and comets. The complete catalogue of minor planet orbits (sometimes referred to as the "Minor Planet Catalogue") may also be freely downloaded. In addition to astrometric data, the ...

Harvey Mudd College
Harvey Mudd College (HMC) is a private liberal arts college in Claremont, California, focused on science and engineering. It is part of the Claremont Colleges, which share adjoining campus grounds and resources. The college enrolled 902 undergraduate students and awards the Bachelor of Science degree. The college was funded by the friends and family of Harvey Seeley Mudd, one of the initial investors in the Cyprus Mines Corporation. Although involved in the planning of the new institution, Mudd died before it opened in 1955. The campus was designed by Edward Durell Stone in a modernist brutalist style. History Harvey Mudd College was founded in 1955. Classes began in 1957 with a class of 48 students, 7 faculty and one building–Mildred E. Mudd Hall, a dormitory. Classes and meals took place at Claremont Men's College (Claremont McKenna College), and labs in the Baxter Science Building until additional buildings could be built: Jacobs Science Building (1959), Thomas-Garett ...

Equatorial Mount
An equatorial mount is a mount for instruments that compensates for Earth's rotation by having one rotational axis, called ''polar axis'', parallel to the Earth's axis of rotation. This type of mount is used for astronomical telescope mount, telescopes and cameras. The advantage of an equatorial mount lies in its ability to allow the instrument attached to it to stay fixed on any celestial object with diurnal motion by driving one axis at a constant speed. Such an arrangement is called a ''sidereal drive'' or ''clock drive''. Equatorial mounts achieve this by aligning their rotational axis with the Earth, a process known as ''polar alignment''. Astronomical telescope mounts In astronomical telescope mounts, the equatorial axis (the ''right ascension'') is paired with a second perpendicular coordinate axis, axis of motion (known as the ''declination''). The equatorial axis of the mount is often equipped with a motorized "''clock drive''", that rotates that axis one revolution e ...

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] |
Cloudcroft Observatory
Cloudcroft Observatory, ( obs. code: V29) is an astronomical observatory located in the Lincoln National Forest near Cloudcroft, New Mexico, approximately northeast of Alamogordo. It is owned by the Tzec Maun Foundation, a private astronomical organization. Known as the Cloudcroft Electro-Optical Research Facility when it was built in 1962, it was owned by the U.S. Air Force (USAF) until 1982 and initially operated by the Air Force Avionics Laboratory (AFAL). It was used as part of a project to develop new techniques for detecting satellites with electronic imaging devices, which were eventually to replace Project Space Track's Baker-Nunn photographic system. From 1995 to 2002, the facility was known as the NASA Orbital Debris Observatory and hosted two telescopes funded and operated by NASA. History The site near Cloudcroft was selected by AFAL in 1961 after several months of site characterization, and construction began in 1962. The First light of the Electro-Op ...

Minor Planet
According to the International Astronomical Union (IAU), a minor planet is an astronomical object in direct orbit around the Sun that is exclusively classified as neither a planet nor a comet. Before 2006, the IAU officially used the term ''minor planet'', but that year's meeting IAU definition of planet, reclassified minor planets and comets into dwarf planets and Small Solar System body, small Solar System bodies (SSSBs).Press release, IAU 2006 General Assembly: Result of the IAU Resolution votes International Astronomical Union, August 24, 2006. Accessed May 5, 2008. In contrast to the eight official planets of the Solar System, all minor planets fail to clearing the neighborhood, clear their orbital neighborhood.

Cassegrain Reflector
The Cassegrain reflector is a combination of a primary concave mirror and a secondary convex mirror, often used in optical telescopes and Antenna (radio), radio antennas, the main characteristic being that the optical path folds back onto itself, relative to the optical system's primary mirror entrance aperture. This design puts the Focus (optics), focal point at a convenient location behind the primary mirror and the convex secondary adds a Telephoto lens, telephoto effect creating a much longer focal length in a mechanically short system. In a symmetrical Cassegrain both mirrors are aligned about the optical axis, and the primary mirror usually contains a hole in the center, thus permitting the light to reach an eyepiece, a camera, or an image sensor. Alternatively, as in many radio telescopes, the final focus may be in front of the primary. In an asymmetrical Cassegrain, the mirror(s) may be tilted to avoid obscuration of the primary or to avoid the need for a hole in the prima ...
