Merate Astronomical Observatory
Merate Astronomical Observatory is an old observatory in Merate (Lecco), Italy. It has housed a 1-meter Zeiss telescope since 1926. This ''Zeiss di Merate'' is a reflecting telescope on an equatorial mount and is one of the largest telescopes funded by the ''Regno d'Italia'' (" Kingdom of Italy") before Italy became republic in 1946. The same type of Zeiss telescope was also installed at the Hamburg-Bergedorf Observatory and the Royal Observatory of Belgium.

Observatory
An observatory is a location used for observing terrestrial, marine, or celestial events. Astronomy, climatology/meteorology, geophysical, oceanography and volcanology are examples of disciplines for which observatories have been constructed. Historically, observatories were as simple as containing an astronomical sextant (for measuring the distance between stars) or Stonehenge (which has some alignments on astronomical phenomena). Astronomical observatories Astronomical observatories are mainly divided into four categories: space-based, airborne, ground-based, and underground-based. Ground-based observatories Ground-based observatories, located on the surface of Earth, are used to make observations in the radio and visible light portions of the electromagnetic spectrum. Most optical telescopes are housed within a dome or similar structure, to protect the delicate instruments from the elements. Telescope domes have a slit or other opening in the roof that can be opened ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Merate
Merate ( Brianzöö: ) is a municipality of 14,872 inhabitants in the province of Lecco, in the northern Italian region of Lombardy. It is served by Cernusco-Merate railway station. History The name ''Melatum'' appeared for the first time in the 4th century; it may be derived from the Greek for black/gloomy/dark because of the presence of woods, or from the Italian for apple (mela): an important fruit from the region. During the fighting between the Torriani and the Visconti families for the supremacy of Milan, Merate (in particular the castle) suffered considerable damage. It recovered during the 17th century after being decimated by the plague; finally becoming one of the richest towns of the region, after Lecco. At the beginning of the 16th century an academic institute was constructed: at the end of the 18th century the young writer/poet Alessandro Manzoni studied at this school, and after his death the school took on his name. After the unification of Italy Merate gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Zeiss AG
Carl Zeiss AG (), branded as ZEISS, is a German manufacturer of optical systems and optoelectronics, founded in Jena, Germany in 1846 by optician Carl Zeiss. Together with Ernst Abbe (joined 1866) and Otto Schott (joined 1884) he laid the foundation for today's multi-national company.

Reflecting Telescope
A reflecting telescope (also called a reflector) is a telescope that uses a single or a combination of curved mirrors that reflect light and form an image. The reflecting telescope was invented in the 17th century by Isaac Newton as an alternative to the refracting telescope which, at that time, was a design that suffered from severe chromatic aberration. Although reflecting telescopes produce other types of optical aberrations, it is a design that allows for very large diameter objectives. Almost all of the major telescopes used in astronomy research are reflectors. Many variant forms are in use and some employ extra optical elements to improve image quality or place the image in a mechanically advantageous position. Since reflecting telescopes use mirrors, the design is sometimes referred to as a catoptric telescope. From the time of Newton to the 1800s, the mirror itself was made of metal usually speculum metal. This type included Newton's first designs and even the larges ...

Equatorial Mount
An equatorial mount is a mount for instruments that compensates for Earth's rotation by having one rotational axis, the polar axis, parallel to the Earth's axis of rotation. This type of mount is used for astronomical 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 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 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 every 23 hours and 56 minutes in exact sync with th ...

Kingdom Of Italy (1861–1946)
The Kingdom of Italy ( it, Regno d'Italia) was a state that existed from 1861, when Victor Emmanuel II of Kingdom of Sardinia, Sardinia was proclamation of the Kingdom of Italy, proclaimed King of Italy, until 1946, when civil discontent led to an 1946 Italian institutional referendum, institutional referendum to abandon the monarchy and form the modern Italy, Italian Republic. The state resulted from a decades-long process, the ''Italian unification, Risorgimento'', of consolidating the different states of the Italian Peninsula into a single state. That process was influenced by the House of Savoy, Savoy-led Kingdom of Sardinia, which can be considered Italy's legal Succession of states, predecessor state. Italy Third Italian War of Independence, declared war on Austrian Empire, Austria in alliance with Kingdom of Prussia, Prussia in 1866 and received the region of Veneto following their victory. Italian troops Capture of Rome, entered Rome in 1870, ending Papal States, more tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hamburg-Bergedorf Observatory
Hamburg Observatory (german: Hamburger Sternwarte) is an astronomical observatory located in the Bergedorf borough of the city of Hamburg in northern Germany. It is owned and operated by the University of Hamburg, Germany since 1968, although it was founded in 1825 by the City of Hamburg and moved to its present location in 1912. It has operated telescopes at Bergedorf, at two previous locations in Hamburg, at other observatories around the world, and it has also supported space missions. The largest near-Earth object was discovered at this Observatory by German astronomer Walter Baade at the Bergedorf Observatory in Hamburg on 23 October 1924. That asteroid, 1036 Ganymed is about 20 miles (35 km) in diameter. The Hamburg 1-meter reflector telescope (first light 1911) was one of the biggest telescopes in Europe at that time, and by some measures the fourth largest in the World. The Observatory also has an old style Great Refractor (a ''Großen Refraktor''), a long telescope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Observatory Of Belgium
The Royal Observatory of Belgium (french: link=no, Observatoire Royal de Belgique, nl, Koninklijke Sterrenwacht van België), has been situated in the Uccle municipality of Brussels (Belgium) since 1890. It was first established in Saint-Josse-ten-Noode in 1826 by William I under the impulse of Adolphe Quetelet. It was home to a diameter aperture Zeiss reflector in the first half of the 20th century, one of the largest telescopes in the world at the time.

List Of Astronomical Observatories
This is a list of astronomical observatories ordered by name, along with initial dates of operation (where an accurate date is available) and location. The list also includes a final year of operation for many observatories that are no longer in operation. While other sciences, such as volcanology and meteorology, also use facilities called observatories for research and observations, this list is limited to observatories that are used to observe celestial objects. Astronomical observatories are mainly divided into four categories: space-based, airborne, ground-based, and underground-based. Many modern telescopes and observatories are located in space to observe astronomical objects in wavelengths of the electromagnetic spectrum that cannot penetrate the Earth's atmosphere (such as ultraviolet radiation, X-rays, and gamma rays) and are thus impossible to observe using ground-based telescopes. Being above the atmosphere, these space observatories can also avoid the effect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
