MPG/ESO-2,2-m-Teleskop

Hauptspiegel des MPG/ESO-2,2-m-Teleskops bei geöffneter Kuppel

Das MPG/ESO-2,2-m-Teleskop (engl. MPG/ESO 2.2 m Telescope) ist ein Spiegelteleskop der ESO in Ritchey-Chrétien-Montierung mit 2,2 Metern Apertur und Teil des La-Silla-Observatoriums in Chile. Gebaut wurde es 1983 von der Firma Zeiss und ist seit 1984 in Betrieb. Es ist eine unbefristete Leihgabe des Max-Planck-Institut für Astronomie (MPIA) mit Sitz in Heidelberg, als Teil der Max-Planck-Gesellschaft (MPG) an die Europäische Südsternwarte ESO. Die Beobachtungszeiten am Teleskop werden zwischen MPIA und ESO aufgeteilt, während Betrieb und Wartung in der Verantwortung der ESO liegen.[1] Das Teleskop befindet sich in einer Höhe von 2335 m.[1]

Instrumente

Das optische und Nahinfrarot-Teleskop ist mit drei Instrumenten ausgerüstet:

  • Wide Field Imager
  • GROND, der Gamma-Ray Burst Optical/Near-Infrared Detector, mit dem man die Gammablitze erforscht, die wohl energiereichsten Energieausbrüche im gesamten Universum
  • FEROS, ein hochauflösender Spektrograf, für detaillierte Studien an Sternen[2]

Der Wide-Field-Imager wurde genutzt, um den Gaia Ecliptic Pole Catalogue (GEPC) zu erstellen, der für die Kalibrierung der Gaia-Mission gebraucht wurde.[3]

An amazing vista of the Lagoon Nebula taken with the 67-million-pixel Wide Field Imager attached to the MPG/ESO 2.2-metre telescope at the La Silla Observatory in Chile. The image covers more than one and a half square degree— an area eight times larger than that of the Full Moon — with a total of about 370 million pixels. It is based on images acquired using three different broadband filters (B, V, R) and one narrow-band filter (H-alpha).

This image of the well-known NGC 4755 cluster or Jewel Box was taken with the Wide Field Imager (WFI) on the MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory. It highlights the cluster and its rich surroundings in all their multicoloured glory.

Orion Nebula MPG ESO 2.2-metre telescope at the La Silla Observatory.jpg

This new image of the Orion Nebula was captured using the Wide Field Imager camera on the MPG/ESO 2.2-metre telescope at the La Silla Observatory, Chile. This image is a composite of several exposures taken through a total of five different filters. Light that passed through a red filter, as well as light from a filter that shows the glowing hydrogen gas, is coloured red. Light in the yellow–green part of the spectrum is coloured green, blue light is coloured blue and light that passed through an ultraviolet filter has been coloured purple. The exposure times were about 52 minutes through each filter.

One square degree image of the Tarantula Nebula and its surroundings. The spidery nebula is seen in the upper-centre of the image. Slightly to the lower-right, a web of filaments harbours the famous supernova SN 1987A (see below). Many other reddish nebulae are visible in the image, as well as a cluster of young stars on the left, known as NGC 2100. Technical information: the image is based on observations carried out by Joao Alves (Calar Alto, Spain), Benoit Vandame and Yuri Beletski (ESO) with the Wide Field Imager (WFI) at the 2.2-m telescope on La Silla. These data consist of a 2x2 WFI mosaic in the B- and V-bands, and in the H-alpha and [OIII] narrow bands. The data were first processed with the ESO/MVM pipeline by the Advanced Data Products (ADP) group at ESO.

The 2.2m telescope at La Silla has been in operation since early 1984 and is on indefinite loan to ESO from the Max Planck Gesellschaft. Operation and maintenance of the telescope is the responsibility of ESO. The telescope (which is a fork mounted Ritchey-Chretien) was built by Zeiss and has been in use at La Silla since 1984. It is equipped with WFI, FEROS and GROND.
