These data were taken from a 7'x 7' area observed for 14 hours with the Omega Prime camera on the 3.5-m Calar Alto telescope. We derive H-band number counts, colour-magnitude diagrams and colour histograms. We review our Pure Luminosity Evolution galaxy count models based on the spectral synthesis models of Bruzual & Charlot. These PLE models give an excellent fit to the our H band count data to H<22.5 and HDF count data to H<28.
