La Silla Facilities
La Silla, in the southern part of the Atacama desert, 600 km north of Santiago de Chile and at an altitude of 2400 metres is the home of ESO's original observing site.
Here ESO operates two major telescopes: the 3.6m telescope, and the New Technology Telescope (NTT). They are equipped with state of the art instruments either built completely by ESO or by external consortia, with substantial contribution by ESO.
La Silla Observatory is hosting regularly Visitor Instruments that are attached to a telescope, for the duration of a run of observation and then is removed from the telescope.
On February 27, 2014, a call for ideas for the NTT has been opened, see the announcement here. The deadline is March 31, 2014.
