Photometry is presented of 907 galaxies brighter that b(26.25) = 20.5 in a 1.83 x 1.83 deg area centered on the southern cluster Sersic 129-01 in the u, b, r and i bands. The slopes and zero-points of the color-absolute magnitude diagrams agree well with other clusters including Coma and the rich cluster Shapley 8 suggesting they are independent of cluster environment. The (u-b) against (b-i) diagram distinguishes well between morphological types. The reddening obtained by a number of methods disagrees with that of Griersmith (1982). A mass of 7.4 x 10 to the 13th solar masses is found for the elliptical dominated component of the cluster and (M/L)b = 59.
