Observations of the Perseus Cluster have been made with the Westerbork Telescope at 610 MHz. Details of the observations and reduction procedure are given. The dynamic range within the maps exceeds 1000. A catalog of 50 sources from the field is presented, together with special information, where available. Several newly detected sources are identified with cluster galaxies. A faint extension found close to NGC 1265 suggests that the main body of this tailed source has been bent by buoyancy forces. On the assumption that this is the case, a conservative lower limit to the mass of the Perseus Cluster of 1.4 x 10 to the 15th solar masses is derived. This reinforces previous arguments from the virial theorem that the cluster is bound. The origin of the extended component surrounding NGC 1275 is discussed, and a 610/1415-MHz spectral-index distribution for it is presented. Its amorphous structure may be influenced by the presence of the cluster gas, but comparisons with similar-resolution X-ray observations are inconclusive. No evidence is found for the existence of the previously reported cluster halo of approximately 65 x 25 arcmin, 3C 84B.
