The Kawkasskaja gornaja obserwatorija GAISCH MGU ( Russian Кавказская горная обсерватория ГАИШ МГУ ) is an observatory of the Sternberg Institute for Astronomy on the northeast ridge of the Shahatmas in the Russian Caucasus , which was opened in 2014 in 2112 m.
The main instrument of the observatory is a reflecting telescope with a diameter of 2.5 m .
history
The Russian government decided in January 2006 to buy a 2.5-meter telescope for € 14,200,000. At the end of the year, the delivery was agreed with SAGEM-REOSC, MAVEG GmbH and Lomonossow University Moscow (MGU) and the residential and technical facilities were built.
In July 2007 the seeing monitor was installed, two years later telescopes for the MASTER II network. The dome for the 2.5 m telescope was erected in August 2012 and the mount installed in it the following year .
The official opening of the observatory took place on December 13, 2014 shortly after the first light in November.
Instruments
2.5 m telescope
The reflector telescope is equipped with five ports (1 Cassegrain focus and 4 Nasmyth focus ). The following instruments are planned for this:
- Photometer (4k × 4k CCD camera consisting of two sensors of the type E2V CCD44-82, built by the Niels Bohr Institute ), equipped with UBVRI , SDSS and narrow-band filters
- Infrared camera spectrometer (IR detector with a working field of 1k × 1k), filters for J, H, Ks, K , Fe , methane and a grism with a resolution of R ~ 1500
- EMCCD camera for speckle analysis .
- low resolution optical spectrographs
- High-resolution spectrograph connected via optical fiber .
Seeing monitor
The task of the seeing monitor is to support the collection of statistics and the observations via the main telescope. It consists of a 12-inch MEADE RCX400 telescope, which is equipped with a MASS / DIMM instrument and is mounted on a column about 5 m above the floor.
MASTER Kislovodsk
The remote-controlled telescopes of the MASTER II network monitor the sky over a wide area. The aim of the surveillance is the discovery and tracking of gamma-ray bursts , supernovae and similar short-term events, as well as the discovery of asteroids .
- MASTER II - two Hamilton telescopes of the Santel 400 type, each with an aperture of 40 cm and a field of view of 1.5 °, equipped with a CCD camera. Both telescopes are installed on a common mount on a 9 m high tower.
- MASTER-VWF4, two identical devices 702 m apart, each with two 11 megapixel CCD cameras. These are provided with commercially available 35 mm photo lenses such as the Carl Zeiss Planar T * 85 / 1.4 ZF or the Nikkor 50 mm ; the entire field of vision thus reaches up to 4060 deg² .
