TEMPO.CO, Bandung –Bosscha Observatory or commonly called the Lembang Observatory is one of the oldest stargazing places in Indonesia.
This observatory was founded by the Nederlandsch-Indische Sterrenkundige Vereeniging (NISV) or the Dutch East Indies Star Association since 1923. Here, there are several telescope large used for research.
Quoting from the Krisnadwipayana University page, some of these telescopes are:
1. Ganda Zeiss Refractor Telescope
This telescope is a refractor type (using a lens) and consists of 2 main telescopes and 1 finder telescope. The diameter of the main telescope is 60 cm with a focal length of almost 11 m, and the search telescope is 40 cm in diameter. This main instrument has been used for various astronomical research, astrometric observations, in particular to obtain visual orbits of double stars.
2. The Milky Way Schmidt Telescope
The Schmidt Milky Way telescope has a Schmidt optical system, so it is often called the Schmidt Camera. This binocular has a correction lens diameter of 51 cm, a mirror diameter of 71 cm, and a focal length of 127 cm. This tool is usually used to study the Milky Way galaxy, study the spectrum of stars, observe asteroids, supernovas, Novas to determine their brightness and chemical composition, and to photograph celestial objects.
3. Telescopic Refractor Bamberg
The Bamberg binoculars are also a large refractor at Bosscha Observatory, with a lens diameter of 37 cm and a focal length of 7 m. The binoculars are housed in a semi-cylindrical roof building with a sliding roof that can move back and forth to open or close.
Due to its construction, the scope of this telescope is limited to observations of celestial bodies with a zenith distance of 60 degrees, or for celestial bodies higher than 30 degrees and azimuths in the East-South-West sector.
4. GOTO Cas Cassegrain Telescope
The Goto telescope is a Cassegrain reflector with a main mirror diameter of 45 cm. The primary mirror in the form of a parabola has a focal length of 1.8 m and a secondary mirror in the form of a hyperbola has a focal length of 5.4 m. With this telescope, objects can be directly observed by entering data on the position of the object.
Observational data will be entered into data storage media directly. These binoculars can also be used to measure the intensity of starlight as well as observations of the star’s spectrum. Equipped with spectrograph and photoelectric-photometer
5. Telescope Refractor Unitron
The Unitron telescope is a refractor telescope with an objective lens of 102 mm in diameter and a focal length of 1500 mm. In terms of size, these binoculars are used for observations of the sun and the moon, and are widely used for student practicums. With its small size and light weight, these binoculars are easy to carry and have been used several times on expeditions to observe total solar eclipses.
6. Solar Telescope
This telescope is a solar telescope consisting of 3 Coronado telescopes with 3 different filters, as well as a completely self-made solar image projection telescope. This infrastructure is a donation from the Ministry of Education, Science and Culture, Netherlands, Leids Kerkhoven-Bosscha Fonds, Ministry of National Education, and the State Ministry of Research and Technology.
7. Telescope radio 2.3m
The Bosscha 2.3m radio telescope is an SRT (Small Radio Telescope) type radio instrument designed by the MIT-Haystack Observatory and manufactured by the Cassi Corporation.
Telescope Bosscha Observatory it works at a wavelength of 21 cm or in the frequency range of 1400-1440 MHz. This telescope can be used to observe distant objects such as extragalaxies and quasars.
