essentially a twin of the 1.5m telescope at the Observatoire de Haute
Provence. It is mounted in an English cradle and is used at the f/14.9
Cassegrain (the f/31.4 Coude' is not available any more). The telescope
is at a geographical location of 70°44'12"865W 29°15'7"422S
and an altitude of 2335 metres.
Telescope operating manual
At present two instruments are offered at the ESO 1.52m telescope:
spectrograph and FEROS
. However FEROS will be moved to the
MPG/ESO 2.2-m Telescope
at the beginning
The B&C spectrograph is the last of three spectrographs
of this type once in use at La Silla. In particular this is the instrument
that until Dec. 1992 was mounted at the ESO/MPI 2.2m telescope although
major changes have been applied since then.
It is equipped with a dioptric camera having an efficiency
of ~87% between 430nm and 900nm and >78% for wavelengths <430nm.
A major improvement has been the installation of the new
CCD#39 , which considerably enhanced
the sensitivity of the system. Anyway since October 1999 we are using
another detector, CCD#38 , which
is basically a twin of the previous one. This means that the global
instrument performance is not dimished.
is the F
iber fed E
pectrograph is a fiber-fed bench-mounted
prism-crossdispersed echelle spectrograph. It was operated at the ESO 1.52-m
telescope at La Silla from the end of 1998 till Sep-2002. In October 2002
it was moved to the MPG/ESO-2.20m telescope
It works in quasi Littrow mode and in white pupil configuration. For
the object and the nearby sky, the complete optical spectrum from 360-920nm
is recorded in one exposure with a resolving power of 48,000 by the
use of a two-beam, two-slice image slicer. It is the first instrument
on La Silla for which a complete automatic on-line data reduction is
running, allowing the observer to go back from the mountain ready to write
the paper !!
There is nothing to be set in FEROS, therefore there is no
set-up form. The only information you have to notify to the 2p2team
is which side of the pier you need the telescope.
You can submit such request using the web-based
Remedy interface accessible from here or from the La Silla web page.
