The Perseus–Pisces Supercluster is one of two dominant concentrations of galaxies (the other being the Local supercluster) in the nearby universe (within 300 million light years). This supercluster also borders a prominent void, the Taurus Void , and is part of the Perseus–Pegasus Filament which stretches for roughly a billion light years .
It consisted of two known rich clusters and one newly discovered cluster as a result of the study that discovered it. The then known clusters were Cl 1604+4304 (z=0.897) and Cl 1604+4321 (z=0.924), which then known to have 21 and 42 known galaxies respectively. The then newly discovered cluster was located at 16 h 04 m 25.7 s, +43° 14′ 44.7 ...

The Perseus–Pegasus Filament is a galaxy filament containing the Perseus–Pisces Supercluster and stretching for roughly a billion light-years (or over 300/h Mpc). Currently, it is considered to be one of the largest known structures in the universe. [note 1] This filament is adjacent to the Pisces–Cetus Supercluster Complex.
The Alpha Persei Cluster, also known as Melotte 20 or Collinder 39, is an open cluster of stars in the northern constellation of Perseus. To the naked eye, the cluster consists of several blue-hued spectral type B stars. The most luminous member is the ~2nd magnitude yellow supergiant Mirfak, also known as Alpha Persei.
This was the first super-large large-scale structure or pseudo-structure in the universe to be discovered. The CfA Homunculus lies at the heart of the Great Wall, and the Coma Supercluster forms most of the homunculus structure. The Coma Cluster lies at the core.

The Southern Supercluster is a branch of a larger filament extending from the Centaurus Cluster that is known as the Southern Supercluster Strand which also encompasses the Telescopium−Grus Cloud. The Southern Supercluster Srand extends all the way to the Perseus–Pisces Supercluster .
