A number of special image processing techniques are known from the literature about comets, from publications about galaxies or from solar corona and remote sensing research. The aim of these processing methods is to enhance small irregular intensity variations or asymmetries, to compare these effects between different spectral bands and to analyze their spatial and temporal behaviour. This paper shows that a number of morphological phenomena can be found in ground-based observations of comet Halley when these or similar techniques are applied to continuum corrected narrow band gas emission images.
