Jyväskylä
Jyväskylä () is a city and municipality in Finland in the western part of the Finnish Lakeland. It is located about 150 km north-east from Tampere, the third largest city in Finland; and about 270 km north from Helsinki, the capital of Finland. The Jyväskylä sub-region includes Jyväskylä, Hankasalmi, Laukaa, Petäjävesi, Toivakka, and Uurainen. Other border municipalities of Jyväskylä are Joutsa, Jämsä and Luhanka. Jyväskylä is the largest city in the region of Central Finland and in the Finnish Lakeland; as of , Jyväskylä had a population of . The city has been one of the fastest-growing cities in Finland during the 20th century, when in 1940, there were only 8,000 inhabitants in Jyväskylä. Elias Lönnrot, the compiler of the Finnish national epic, the ''Kalevala'', gave the city the nickname "Athens of Finland". This nickname refers to the major role of Jyväskylä as an educational centre. The works of the notable Finnish architect, Alvar Aalto, can ...

Finland
Finland ( fi, Suomi ; sv, Finland ), officially the Republic of Finland (; ), is a Nordic country in Northern Europe. It shares land borders with Sweden to the northwest, Norway to the north, and Russia to the east, with the Gulf of Bothnia to the west and the Gulf of Finland across Estonia to the south. Finland covers an area of with a population of 5.6 million. Helsinki is the capital and largest city, forming a larger metropolitan area with the neighbouring cities of Espoo, Kauniainen, and Vantaa. The vast majority of the population are ethnic Finns. Finnish, alongside Swedish, are the official languages. Swedish is the native language of 5.2% of the population. Finland's climate varies from humid continental in the south to the boreal in the north. The land cover is primarily a boreal forest biome, with more than 180,000 recorded lakes. Finland was first inhabited around 9000 BC after the Last Glacial Period. The Stone Age introduced several differ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meade Instruments
The Meade Instruments (also shortened to Meade) is an American multinational company headquartered in Watsonville, California, that manufactures, imports, and distributes telescopes, binoculars, spotting scopes, microscopes, CCD cameras, and telescope accessories for the consumer market. It is the world's largest manufacturer of telescopes. Besides selling under its "Meade" brand name, the company sells solar telescopes under the brand "Coronado". Origins and history Founded in 1972 by John Diebel, Meade started as a mail order seller of small refracting telescopes and telescope accessories manufactured by the Japan-based Towa Optical Manufacturing Company. Meade started manufacturing its own line of products in 1976, introducing 6" and 8" reflecting telescopes models in 1977. In 1980, the company ventured into the Schmidt-Cassegrain market that up to that time had been dominated by Celestron Corporation. Meade has a long history of litigation with other companies over infri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meade LX200
The Meade LX200 is a family of commercial telescopes produced by Meade Instruments launched in 1992 with 8" (20.32 cm) and a 10" (25.4 cm) Schmidt–Cassegrain models on computerized altazimuth mounts. Two larger models, a 12" (30.48 cm) and a 16" (40.64 cm), quickly followed. The original version was later informally named the "classic" LX200 as newer upgraded versions replaced it. The first of these was the LX200GPS, which featured global positioning system electronics. A LX200GPS was later added to the line. The advantage of the LX200 was price for its performance, which was accomplished by using electronics and software to equal the pointing performance of more expensive systems. Software and optical encoders corrected for errors, and the telescope also came with auto-guiding CCD and planetarium software. A related series introduced in 2005 was the even higher end RCX400 (later renamed LX400-ACF), with new optics and a motorized focus/collimation sys ...

Amateur Astronomy
Amateur astronomy is a hobby where participants enjoy observing or imaging celestial objects in the sky using the unaided eye, binoculars, or telescopes. Even though scientific research may not be their primary goal, some amateur astronomers make contributions in doing citizen science, such as by monitoring variable stars, double stars, sunspots, or occultations of stars by the Moon or asteroids, or by discovering transient astronomical events, such as comets, galactic novae or supernovae in other galaxies. Amateur astronomers do not use the field of astronomy as their primary source of income or support, and usually have no professional degree in astrophysics or advanced academic training in the subject. Most amateurs are hobbyists, while others have a high degree of experience in astronomy and may often assist and work alongside professional astronomers. Many astronomers have studied the sky throughout history in an amateur framework; however, since the beginning of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astronomical 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 during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
