Bosscha, observatory, located in Lembang, West Java stand on the height of 1310 meters above sea level (asl).
Bosscha has a five star binoculars are Zeiss telescope, Schimdt Bimasakti Telescope, Mamberg Telescope, Cassegrain Telescope GOTO, and Unitron Telescope.
Zeiss telescope is the first and largest telescopes located on a circular domed building which operated since 1928, and is still running fine until now.
This telescope placed in the middle of the floor space can be up and down according to needs, and a dome that could rotate to follow the motion of stars. Vault and floor mechanical system is still in the original condition of the construction in the era before the Dutch.
Zeiss telescope objective lens has two pieces, each 60cm in diameter and focus 10.7 meters. Have binoculars and search for the diffraction grating placed in front of the lens. This telescope is useful for observing double stars, moon and planets, the motion of stars, star clusters members, and special objects such as comets and proper motion stars.
Schmidt telescope mirror or the Milky Way was 71.12 cm in diameter, 50cm diameter lens correction, and the focus point of the fire or 2.5 meters. The Hubble telescope was named after the Milky Way because most of its activities in use to examine and observe the movement of the Milky Way.
Binoculars Bamberg, has a 37cm diameter lens, and spots / focus 7m. Equipped with fotoelectrik fotometer to measure the intensity of starlight /star light scale, so that the distance scale can be expected to earth star.
Cassegrain binoculars from GOTO, has a primary mirror diameter of 45cm, 20cm diameter secondary mirror, a combination of hot spot or focus 540cm. Motion is governed by a computer system, equipped with a spectrograph is a tool to measure the spectrum of stars and fotoelectrik fotometer or tool to measure the intensity of starlight. This telescope functions as a data recorder that is connected with the computer.
Most small telescopes at the observatory Bosscha is Unitron telescope. Unitron binoculars have a lens diameter of 10.2 cm and 150cm focal or focus. Unitron telescope primary function is to observe and photograph an eclipse of the moon, solar eclipses, sunspots, and the heavenly bodies is simple.
Bosscha observatory development carried out after the joint review by scientists at the Association of Science or NISV Star Dutch East Indies (Nederlandsch-Indische Vereeniging Sterrenkundige) at the Savoy hotel lobby Homman, Bandung. The main sponsor of the construction of the observatory is Karl Albert Rudolf Bosscha Bosscha, the planter.
Building which was founded in 1920 was never damaged by World War II and in the renovation of the Royal Observatory, Leiden assistance, Warmer and swasey observatory, as well as other scientific and educational institutions.
