Llano Del Hato National Astronomical Observatory
The Llano del Hato National Astronomical Observatory (, code: 303) is an astronomical observatory in Venezuela. It is 3600 meters above sea level and is the country's main observatory. It is situated above the village of Llano del Hato in the Venezuelan Andes, not far from Apartaderos which lies about 50 kilometers north-east of Mérida, Mérida State. Description This facility is the closest major optical observatory to the equator lying at 8 degrees and 47.51 minutes north. It therefore has access to most parts of both the northern and southern skies. It benefits from a very dark site, and its altitude of 3,600 meters (12,000 feet) above sea level means atmospheric turbulence is greatly reduced. The observatory is under the auspices of the Centro de Investigaciones de Astronomia (CIDA), the main astronomical research body in Venezuela. CIDA conducts many projects in collaboration with other research organizations, academic institutions and international bodies. It also condu ...

Astrograph
An astrograph (or astrographic camera) is a telescope designed for the sole purpose of astrophotography. Astrographs are mostly used in wide-field astronomical surveys of the sky and for detection of objects such as asteroids, meteors, and comets. Improvements in photography in the middle 19th century led to designs dedicated to astrophotography, and they were also popular in the 20th century. As in other photography, chemicals were used that respond to light, recorded on a glass photographic plate or sometimes on photographic film. Many observatories of this period used an astrograph, beside instruments like the transit telescope, great refractors, and chronometers, or instruments for observing the Sun. Astrographs were often used to make surveys of the night sky, and one of the famous projects was Carte du Ciel. Discoveries using an astrograph include then-planet Pluto. Rather than looking through the telescope, it was discovered by using a blink comparator with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jürgen Stock (astronomer)
Jürgen Stock (8 July 1923 – 19 March 2004) was a German astronomer, best known for discovering the site of the Cerro Tololo Inter-American Observatory in Chile after a two year search starting in 1960, and was its first director from 1962 to 1965. Stock was bilingual, studied at the University of Hamburg and graduated under Otto Heckmann. In the 1950s he worked at Case-Western Reserve University and Boyden Observatory in South Africa, which uniquely linked him to scientific initiatives in both the northern and southern hemisphere. In 1971, he established the Llano del Hato National Astronomical Observatory, the Venezuelan National Observatory, of which he was a temporary director. The asteroid (4388) Jürgenstock was named after him. Early life and education Jürgen Stock was born in Hamburg on 8 July 1923. His father owned an import business and the family moved to Mexico City in 1925. While German was his native language, he was exposed to Spanish until his return to Germany i ...

Charge-coupled Device
A charge-coupled device (CCD) is an integrated circuit containing an array of linked, or coupled, capacitors. Under the control of an external circuit, each capacitor can transfer its electric charge to a neighboring capacitor. CCD sensors are a major technology used in digital imaging. Overview In a CCD image sensor, pixels are represented by Doping (semiconductor), p-doped metal–oxide–semiconductor (MOS) capacitors. These MOS capacitors, the basic building blocks of a CCD, are biased above the threshold for inversion when image acquisition begins, allowing the conversion of incoming photons into electron charges at the semiconductor-oxide interface; the CCD is then used to read out these charges. Although CCDs are not the only technology to allow for light detection, CCD image sensors are widely used in professional, medical, and scientific applications where high-quality image data are required. In applications with less exacting quality demands, such as consumer and pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Camera
A digital camera, also called a digicam, is a camera that captures photographs in Digital data storage, digital memory. Most cameras produced today are digital, largely replacing those that capture images on photographic film or film stock. Digital cameras are now widely incorporated into mobile devices like smartphones with the same or more capabilities and features of dedicated cameras. High-end, high-definition dedicated cameras are still commonly used by professionals and those who desire to take higher-quality photographs. Digital and digital movie cameras share an optical system, typically using a Camera lens, lens with a variable Diaphragm (optics), diaphragm to focus light onto an image pickup device. The diaphragm and Shutter (photography), shutter admit a controlled amount of light to the image, just as with film, but the image pickup device is electronic rather than chemical. However, unlike film cameras, digital cameras can display images on a screen immediately afte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Samuel Oschin Telescope
The Samuel Oschin telescope (), also called the Oschin Schmidt, is a Schmidt camera at the Palomar Observatory in northern San Diego County, California, United States. It consists of a Schmidt corrector plate and a (f/2.5) mirror. The instrument is strictly a camera; there is no provision for an eyepiece to look through it. It originally used and glass photographic plates. Since the focal plane is curved, these plates had to be preformed in a special jig before being loaded into the camera. Construction on the Schmidt telescope began in 1939 and it was completed in 1948. It was named the Samuel Oschin telescope in 1986. Before that it was just called the Schmidt. In the mid-1980s, the corrector plate was replaced using glass with less chromatic aberration, producing higher quality images over a broader spectrum. Between 2000 and 2001, it was converted to use a CCD imager. The corrector plate was recently replaced using glass that is transparent to a wider range of wavele ...
