Abstract :
[en] Observational techniques and instrumentation applied in ground-based studies of the cometary coma during the post-perihelion phase of the recent passage of Comet Halley are summarized. Applications of a 1.5 m telescope equipped with a coude spectrograph for long slit investigations of spectral intensity distributions, a 1.4 m CAT, coude echelle spectrometer and reticon to evaluate the C-12/C-13 isotopic abundance ratio, and a 50 cm photometric telescope for narrow bandwidth spectroscopy are described. Finally, the 1.5 m Danish telescope, equipped with a CCD camera, collected high spatial resolution photographs of the various coma components when the comet was 0.42 AU from the sun.
