ESO's ruling body is its Council, which delegates day to day responsibility to the Executive under ESO's Director General. Other governing bodies of ESO are: the Finance Committee (FC), the Scientific ...

The 3.6m New Technology Telescope (NTT) saw first light in March 1989. CCD frames were obtained on which stellar images had FWHM diameters of 0.33, indicating the excellent imaging quality of this ...

The 3.58-m New Technology Telescope (NTT) was the first in the world to have a computer-controled mirror ans ESO 3.6-m telescope.

The Call for Proposals for the regular cycles is currently closed. You can no longer submit proposals for the regular cycles. The next call will be released in July 2027. For your convenience you can ...

The ESO Science Newsletter is intended to keep the community informed about current activities of interest at ESO. The newsletter appears roughly every two to three months or whenever important news ...

MATISSE is a four-telescope beam combination instrument operating in the L (between 3.2 and 3.9 μm), M (between 4.5 and 5.0 μm), and N (between 8.0 and 13.0 μm) bands. It operates in a spectroimaging ...

Based on the FAIR principles to make data Findable, Accessible, Interoperable, and Reusable, publications making use of ESO observational data must include the following statement in a footnote or in ...

Extensive extinction measurements were made by Dr. H. Tug, using the 0.6-m Bochum telescope (see below). No correlation was found between extinction coefficients and direction of observation, and ...

The telescope structure is an alt-az mount (see Figure 1) and it is divided into two main parts: the Azimuth Structure and the Altitude Structure. The main structure, including the hosted units and ...

This page contains information about the seeing on La Silla Observatory (ESO, Chile) as reported by the night assistants working in the 4 biggest telescopes (ESO NTT , ESO 3.60m , ESO/MPI 2.20m , ...

All documents and other files linked from this page and highlighted by a red bullet have an internal access only because we need to know who has the documents so we can send updates as necessary. If ...

The procedures for obtaining flat fields are described in greater detail elsewhere (follow the links under the different spectroscopic modes). The different types of flat fields used for spectroscopy ...
