The aim of this paper is to report quite preliminary results obtained with a new multichannel detector put into operation at the Haute Provence Observatory. The observations have been made at the Cassegrain focus of the 1.93 m. The dispersion of the spectrograph was 17 Å. mm−1 at Hα and the slit was 300μ wide. The detector was a cooled SIT TV camera tube commercially available under the name of “Nocticon”. Details on the observing technique have been given elsewhere (Adrianzyk and al., 1978). We will only point out that all the wavelengths are recorded simultaneously : this recording technique is different from the scanning technique the result of which have been recently reviewed by Lacy (1977).
