We have obtained a mosaic of CCD images of the Coma cluster in the V-band covering a region of approximately 0.4°² around both central cluster galaxies NGC 4889 and NGC 4874. An additional frame of ∼ 90arcmin² 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 V_26.5 magnitudes. We estimate that data is complete up to V_26.5∼22.5 and the surface brightness limiting detection value is µ∼24mag/arcsec². 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.
