Image of Arp 82, also known as NGC 2535 and NGC 2536, from the Atlas of Peculiar Galaxies by Halton Arp (1966).

In the original catalog, it was in the category: Spiral galaxies - Large, high surface brightness companions. The larger galaxy's inner arms have evenly spaced "beads on a string" star clusters, suggesting recent gravitational interactions between the galaxy pair led to a burst of star formation.
