The Antlia Cluster is a small-scaled galaxy cluster in center of the constellation, several small galaxies with 12th or 13th magnitude are distributed in span of about a degree around NGC3268. The cluster is floating about 130 millions light years away, one of principal clusters with the Hydra Cluster (Abell 1060) forming the "Hydra galaxy supercluster".
