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 city of Bandung with geographic coordinates 107 ° 36 'east longitude and 6 ° 49' south latitude. This place stands on the land area of 6 hectares, and located at an altitude of 1310 meters above sea level or at an altitude of 630 m from the plateau of Bandung.Code of the International Astronomical Union observatory to observatory Bosscha is 299.
Bosscha Observatory (formerly called Bosscha Sterrenwacht) built by the Nederlandsch-Indische Vereeniging Sterrenkundige (NISV) or the Association of the Dutch East Indies star. At the first meeting NISV, it was decided to build an observatory in Indonesia for the sake of advancing the science of Astronomy in the Dutch East Indies. And in that meeting, Karel Albert Rudolf Bosscha, a landlord at the Malabar tea plantation, willing to be the major funders and promised to provide assistance purchasing telescopes. In recognition of his services K.A.R. Bosscha in the construction of this observatory, hence the name Bosscha immortalized as the name of this observatory.
Construction of the observatory itself is spending less than 5 years since 1923 until 1928.
The first international publication Bosscha Observatory conducted in 1933. However, later observations were to be discontinued because 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 again.
Then 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 institutes and Astronomy formal education in Indonesia.
There are 5 pieces of large telescopes, namely:
Zeiss double refractor telescope
The telescope is used for visual double star observing, measuring the eclipse photometry of stars, watching the image of the crater of the moon, planetary observing, watching the opposition of Mars, Saturn, Jupiter, and to observe the comet's bright and detailed image of the other heavenly bodies. The telescope has two objective lenses with a diameter of each lens is 60 cm, with hotspots or the focus is 10.7 meters.
Schmidt telescope Milky Way
This telescope is used to study the structure of the Milky Way, study the spectrum of stars, observe the asteroid, supernova, bright and Nova for the specified chemical composition, and to take pictures of sky objects. 71.12 cm diameter lens. Biconcaf-diameter lens correction biconfex 50 cm. Flame point / focus of 2.5 meters. Also equipped with a prism refracting the prime corner of 6.10, to obtain spectra of stars.This dispersion prism 312A at H-gamma every night. The tools are extra-Wedge Sensitometer telescope, to menera blackish scales bright stars, and film recorders
Bamberg refractor telescope
The telescope is used for menera bright stars, determining the distance scale, measuring the eclipse photometry of stars, watching the image of the crater of the moon, solar observations, and to observe other celestial bodies. Equipped with a photoelectric photometer to obtain the scale-bright stars of light intensity that caused electricity. Lens diameter 37 cm. Focal point of a fire or 7 meters.
Cassegrain telescope GOTO
With this telescope, the object can be directly observed by entering the object position data. Then the observation data will be entered into the data storage media directly.Binoculars can also be used to measure the star's light and strong spectral observations of stars. Dilengakapi with a spectrograph and photoelectric-photometer
Unitron refractor telescope
This telescope is used to make observations moon, lunar eclipse observation and solar eclipses, sunspots and photo shoots as well as observations of other celestial objects.With a lens diameter 13 cm, and the focus of 87 cm
