It is suggested that an "Einstein-Straus vacuole" - a region of space time with a metric obtained by solving the equations of general relativity of a mass condensation in an expanding universe with vanishing cosmological constant - surrounds the cluster of galaxies "Abell 194". This hypothesis is shown to predict a distribution of galaxy redshifts that is in better accord with observations than the one expected in the cosmological concordance model.
