Abstract

Deep CCD frames of apparently blank regions of sky have been obtained in the hope of detecting very low surface brightness (LSB) objects in the cluster A1367. The data reduction, and image detection, and selection techniques are discussed. If the galaxies detected are actually cluster members then they are dwarfs and the conclusions of a previous paper on the Fornax cluster are essentially confirmed. One area of variance is that the lowest surface brightness galaxies do not appear to be preferentially concentrated towards the cluster center. This can be explained by there being a much larger density of dwarf galaxies over this bright galaxy-rich region of the universe. Approximately four times as many LSB galaxies are found in this small area as would be expected from the Fornax data. The possible origin and likely intensity of intergalactic light within clusters are discussed.
