Hickson Compact Group 90 (HCG90)

Located in Pisces Austrinus, this scene depicts the mayhem of two elliptical galaxies in a gravitational
dance with a spiral galaxy along with another coffee bean shaped, edge on spiral Seyfert 2 galaxy. There is
a lot of intervening galactic tidal material, as well as the subtle glow of some diffuse intra cluster light.
