Scientific paper

A multichannel detector has been developed for visual stellar and nebular spectroscopy at moderate resolution. It consists of a cooled SIT TV camera tube provisionally mounted at the focus of a coude echelle spectrograph. The video signal is measured and stored in a digital local memory. An on-line computer provides extended reduction facilities in order to have a quick look at the collected data. This equipment has been used for observations of the star CI Cyg, some planetary nebulae (NGC6210, 6543, 6572), and some comparison stars.
