Bosscha Observatory

Bosscha Observatory is one of the oldest star observation in Indonesia. Bosscha Observatory is located in Lembang, West Java, about 15 km in the northern part of Bandung with geographic coordinates 107 ° 36 'east longitude and 6 ° 49' South Latitude. This place stands on 6 hectares of land, and an altitude of 1310 meters above sea level or at an altitude of 630 m from the plateau Bandung. Observatory code for the International Astronomical Union Bosscha observatory is 299.
Bosscha Observatory (formerly called Bosscha Sterrenwacht) built by Sterrenkundige Nederlandsch-Indische Vereeniging (NISV) or the Association of Dutch East Indies star. At the first meeting NISV, it was decided to build an observatory in Indonesia to promote Science Astronomy in the Dutch Indies. And in that meeting, Karel Albert Rudolf Bosscha, a landowner in the Malabar tea plantation, would be the primary funding and promised to provide assistance purchasing binoculars stars. In recognition of his services K.A.R. Bosscha in the construction of this observatory, the Bosscha name immortalized as the name of this observatory.
Development of this observatory alone spent approximately 5 years since 1923 until 1928. The first international publication Bosscha Observatory conducted in 1933. But then had to be stopped due to observations being wake of World War II. After the war, carried out extensive renovations to the observatory is due to the ravages of war until the end of the observatory can operate normally kembali.Kemudian on October 17, 1951, this observatory NISV handed to the government of Indonesia. After Institut Teknologi Bandung (ITB) was established in 1959, Bosscha Observatory became part of the ITB. And since then, Bosscha functioned as research institutions and Astronomy formal education in Indonesia.
There are 5 large telescopes fruit, namely:
• Zeiss double refractor telescope
This telescope is used to observe the visual double stars, measuring the eclipse photometry of stars, watching the image of the moon craters, studied the planets, watch the opposition Mars, Saturn, Jupiter, and to observe the comet's bright image details and other heavenly bodies. This telescope has an objective lens 2 with a diameter of each lens is 60 cm, with focal or focus is 10.7 meters.
• Milky Schmidt telescope
This telescope is used to study the structure of the Milky Way galaxy, studying the spectrum of stars, observed asteroid, supernova, Nova for bright and determined their chemical composition, and to take pictures of sky objects. 71.12 cm diameter lens. Diameter lens correction biconcaf-biconfex 50 cm. Fire point / focus of 2.5 meters. Also equipped with a prism pembias with excellent 6.10 point, to obtain the spectrum of stars. This prism dispersion in H-gamma 312A every night. The tool is extra-WEDGE Sensitometer telescope, to blackish scale menera bright stars, and film recorders
• Bamberg refractor
This telescope is used to menera bright stars, determining the distance scale, measuring the eclipse photometry of stars, watching the image of the moon craters, observations of the sun, and to observe other heavenly bodies. Equipped with a photoelectric-scale fotometer to get light from the star power of light intensity on the caused. Lens diameter 37 cm. Focal point fires or 7 meters.
• Cassegrain telescope GOTO
With this telescope, the object can be directly observed by inserting the object position data. Then the observation data will be entered into the data storage media directly. These binoculars can also be used to measure the star's light and strong spectral observations of stars. Dilengakapi with spectrograph and photoelectric-fotometer
• Unitron refractor
This telescope is used to make the new moon observation, observation of lunar eclipses and solar eclipses, sunspots and shooting as well as observation of the heavenly bodies are another. With a lens diameter is 13 cm and 87 cm focal
