The number of galaxies as a function of the redshift is derived in the framework of the generalized tired light hypothesis. Two new formulae are derived for the flux and the apparent magnitude as functions of the redshift. An application is made to four catalogs of galaxies: 2MRS, SDSS, Glade+ and Ultravista. The role of the limiting apparent magnitude of the position in redshift for the photometric maximum for galaxies is analysed.
