Data of the cluster A 2065 are presented. The magnitudes were integrated up to the isophote corresponding to mpg = 25 sq.arc sec. The completeness limit is 19m.5 and the number of galaxies up to this limit is 132. For the parameters of the Schechter luminosity function the values of α* = -1.25, M*pg = -20.45 were derived and for those of Abell s1 = 1.1, s2 = 0.36. The luminosity segregation of the galaxies is observed only within a magnitude from the brightest galaxy. The ellipticities and position angles of the major axis of galaxies were determined. The observed ellipticity does not depend on the luminosity, diameter or position of galaxies in the cluster. It is shown that an alignment of the galaxy major axis is observed.
