NGC 507, also known as Arp 229, CGCG 502-67, MCG 5-4-44, PGC 5098, UGC 938, and V V 207, is a slit galaxy in the constellation Pisces. It was described by John Dreyer in the New General Catalog as "very faint", "fairly large", "round", "brighter at the center", and located "south of NGC 508". Both NGC 507 and NGC 508 are included in the Atlas of Strange Galaxies, where NGC 507 is described as having "round or nearly round rings with little difference in density".
The galaxy was discovered by William Herschel on September 12, 1784. The NGC 507 group is the largest group of galaxies in the constellation Pisces, containing 9 galaxies brighter than 15th magnitude. Several galaxies from the IC catalog are also present. In addition, the image of this region shows a large number of dimmer background galaxies that probably do not belong to the group. The group is part of the Perseus-Pisces supercluster, also called the Pisces Cluster, along with NGC 383. The main galaxies of the cluster were discovered by William Herschel in 1784.

Structure and Features
NGC 507 is the largest and brightest galaxy in the group. It was studied by Halton Arp, who noticed faint concentric shells in photographs taken with a 200-inch telescope. He added the galaxy to his catalog of strange galaxies as Arp 299. These shells are likely the result of ancient mergers. NGC 507 is also an active galaxy with possible radio shells.
Galaxy NGC 508
Although some sources list NGC 508 as part of Arp 229, Arp's description clearly identifies Arp 229 as belonging specifically to NGC 507. Although the galaxies are similar in angular size, it is unclear whether NGC 508 is physically related to NGC 507.
Central structure of the group
The NGC 507 group shows a number of small substructures in its central core, indicating that the group may still be recruiting other smaller galaxy groups and has not reached its final state. The galaxy NGC 499, located in the center of the second peak of the X-ray halo, may be the central galaxy of another group merging with the NGC 507 group. Unfortunately, it is impossible to determine exactly in which direction NGC 499 is moving.
Distance and position in the supercluster
The main part of the group has the appearance of a chain, but there are also several galaxies located off this chain. The NGC 507 group is located at a distance of 63 Mpc and is part of the main filamentary axis of the Perseus-Pisces supercluster, which also includes the Abell 262, Abell 347, and Abell 426 clusters.
