We present a catalogue of RcIcZ photometry over an area of 0.855 square degrees, centred on the young open cluster NGC 2547. The survey is substantially complete to limits of Rc=21.5, Ic=19.5, Z=19.5. We use the catalogue to define a sample of NGC 2547 candidates with model-dependent masses of about 0.05-1.0M_{sun}_.
