EFOSC History

EFOSC1 on the 3.6m Telescope

The first ESO Faint Object Spectrograph and Camera (EFOSC1) was at the ESO 3.6m telescope till its replacement by EFOSC2 in October, 1997. Although conceptually a very simple instrument it could be used in eight different modes: direct imaging, long slit spectroscopy, slitless spectroscopy, echelle spectroscopy, imaging polarimetry, spectropolarimetry, coronography, and Multiple Object Spectroscopy (MOS). EFOSC1 was equipped with CCD #26, a Tek512 chip with 512x512 pixels of 27 micron size (scale is 0.61 arcsec/pixel).
