Chincarini, G. ; Rood, H. J. Abstract The redshifts (in units of 100 km/s) of the homogeneous sample of Sc I-Sc II galaxies with 14.0-15.0 mag obtained by Rubin et al. (1976) are placed at their galactic locations on an equal-area projection of the celestial sphere. This 'redshift map' and auxiliary maps with narrower 'redshift windows' illustrate the existence of the Hydra/Centaurus and Hercules/A2199 superclusters. They also reveal that the Coma cluster is part of a structure which includes not only A1367 but A779 as well, and may extend more than 200 Mpc across the celestial sphere. Similarly, the Perseus chain of clusters is part of a structure which fills a large fraction or all of the sky. By examining the redshift maps, one could gain the impression that the universe is an irregular three-dimensional 'net' - chains and clumps of galaxies separating vast voids.
