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. 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.
Bosscha Observatory (formerly called Bosscha Sterrenwacht) built by the Nederlandsch-Indische Vereeniging Sterrenkundige (NISV) or the Union Star Dutch East Indies. At the first meeting NISV, it was decided to build an observatory in Indonesia for the promotion 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 telescope purchase. In recognition of his services K.A.R. Bosscha in the construction of this observatory, the name Bosscha immortalized as the name of the observatory.
Development of this observatory alone spent approximately 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 major renovation of the observatory because of damage caused by the 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 the Bandung Institute of Technology (ITB) was founded in 1959, Bosscha Observatory became part of the ITB. And since then, Bosscha functioned as research institutions and the formal education of Astronomy in Indonesia.
There are 5 pieces of large telescopes, namely:
1. Double Zeiss refractor telescope: Telescope was used to observe the visual double stars, measuring the eclipse photometry of stars, watching the image of the crater of the moon, planetary observing, observing opposition Mars, Saturn, Jupiter, and to observe the comet's bright image detail as well as other celestial bodies. This telescope has a second objective lens with a diameter of each lens is 60 cm, with a point or focus fire was 10.7 meters.
2. Schmidt Telescope Milky Way: This telescope is used to study the structure of the Milky Way, study the spectrum of stars, observed asteroid, supernova, bright and determined Nova for chemical composition, and to photograph the object sky. 71.12 cm diameter lens. Biconcaf correction lens diameter of 50 cm-biconfex. Hotspots / focus 2.5 meters. Also equipped with a prism refracting the prime corner of 6.10, to obtain spectra of stars. This prism dispersion at H-gamma-312A each night. The tools are extra-Wedge Sensitometer telescope, to menera blackish scales bright stars, and film recording device
3. Bamberg refractor telescope: Telescope is commonly used to 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 scale-bright star of light intensity in the electricity caused. Lens diameter 37 cm. Focal point of the fire or 7 meters.
4. Cassegrain telescope GOTO: With this telescope, the object can be directly observed by incorporating 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
5. Unitron refractor telescope: Telescope was used to observe the new moon, eclipse observations of the moon and solar eclipses, sunspots and shooting as well as observation of other heavenly bodies. With a lens diameter 13 cm, 87 cm and the focus
Bosscha Observatory visited not solely because it was founded in the last days of Dutch rule. But this is one of the most important observations of this star in the southern hemisphere. The astronomnya participate exchanging information with other star watchers around the world. The importance of Bosscha caused by several factors. Dr. Taufiq Hidayat, head of the observatory, call one of them: Bosscha the only major observatory in the region from Japan to India. Not only that, the location of Bosscha also help the southern sky observations are limited facilities star observations.
Since its founding, the observatory has a telescope the largest in Southeast Asia. New dominance unshakeable next few years as Malaysia will operate the 0.5 meter telescope lens automatic two more years. Thailand will also follow suit, even with fantastic lens: 2.4 meters wide. But until recently Bosscha still dominant. And until now the managers of this observatory dither set a schedule for the students already lining up to guest researchers use telescopes. One of them is a Japanese astronomer, two years ago using binoculars Bosscha to count the stars in the southern region. This research is to position their satellites.
