About the Perseus–Pisces Supercluster

The light we see from it set out 0.257 billion years ago, when the universe was 13.5 billion years old (redshift 0.018).

The map lists it as a supercluster and shows it at the scale of the large-scale universe, drawn on the supergalactic plane.

From Wikipedia

The Perseus–Pisces Supercluster or Perseus–Pisces Filament is one of the largest known structures in the universe. Even at a distance of 250 million light-years, this chain of galaxy clusters extends more than 40° across the northern winter sky.
