The ESO 1.52m Telescope


The Fiber-fed Extended Range Optical
Spectrograph for the ESO 1.52-m telescope


The FEROS instrument is a state-of-the-art bench-mounted high-resolution astronomical echelle spectrograph with very high efficiency and large wavelength range, i.e., it covers the complete optical spectral region in one exposure with a resolution of R=48000.

It is operated at the European Southern Observatory (ESO) in La Silla, Chile, i.e., one of the best astronomical sites in the world. With this type of echelle spectrographs a large variety of stellar spectroscopic observation programs requiring high spectral stability can be carried out.


In October 2002 FEROS was moved from the ESO 1.52m Telescope to the MPG/ESO 2.2m Telescope.

FEROS has been available at the 2.20m since November 2002.

Proposals for Period 70 and 71 can be prepared based on the information below, just remember that exposure times can be scaled by a factor of approximately 1.52*1.52/2.2*2.2 = 0.46 and that the pointing limitations of the ESO 1.52m do not apply at the 2.2m.

For other Period-70+ FEROS information go to the FEROS@2.2m home page.
