Scientific paper

The results of two-color photometry in B and V of galaxies in A1185 are presented. The plates of the 2.6-m telescope of the Biurakan Observatory have been used. The measurements were carried out with the PDS microdensitometer of the Naples Observatory. The rectangular coordinates, total magnitudes and colors, ellipticities and position angles of the major axes of galaxies have been determined. The luminosity functions in B and V are constructed. There is a change of slope in cumulative luminosity functions in both B and V at absolute B and V magnitudes of -19.0 and -20.0 mag, respectively. The brighter and redder the galaxies, the stronger is the concentration to the cluster center.
