We have observed a homogeneous sample of Seyfert 1 and 1.5 galaxies with the aim to determine the luminosity function of Seyfert nuclei. Observations were made with the CCD cameras of Asiago and Loiano Observatories in B, V and R bands in order to isolate the contribution of different stellar populations. A photometric decomposition into three components (disc, bulge and nucleus) was fitted to the observed luminosity profiles to separate the nuclear and the host galaxy contributions and to understand whether underlying galaxies actually behave as “normal” galaxies.
