We have obtained a mosaic of CCD images of the Coma cluster in the V-band covering a region of approximately 0.4 degrees2 around both central cluster galaxies NGC 4889 and NGC 4874. An additional frame of was taken of the south-west region around NGC 4839. We derived a catalogue of 7023 galaxies and 4096 stars containing positions, central surface brightnesses and isophotal V26.5 magnitudes. We estimate that data is complete up to and the surface brightness limiting detection value is . In this paper we present the catalogue (available in electronic form alone), along with a detailed description of the steps concerning the data reduction and quality of the computed parameters.
