The Leo Supercluster is not a particularly famous supercluster. This map below is a plot of the brightest galaxies (from the Principal Galaxies Catalogue) in the vicinity of this supercluster. The supercluster is about 440 million light years from us, and at this distance a fairly weak supercluster like the Leo supercluster is hard to see among all the foreground galaxies. The nearer Coma supercluster is in this area as can be seen from the presence of the large A1367 cluster, and even closer to us is the nearby Virgo cluster at the bottom left of the map.
Below is a list of the major clusters in the Leo Supercluster. The richest cluster is probably the A1185 cluster. Most of the other clusters are rather poor clusters with a richness class of 0. The cluster A1314 is also included in this list although it lies some distance to the north of the supercluster and it may not be a true member.

There has been no proper scientific research conducted on this supercluster. Occasionally, some of the clusters are studied, this is especially true of A1185, which is probably the richest cluster in the supercluster. The cluster was studied by Mahdavi, Geller, Fabricant, Kurtz, Postman and McLean in a paper in 1996. More recently in 2000, Botashev, Verkhodanov, Cardona, Lipovka, Lipovka, Mingaliev and Chavira produced a catalogue of the galaxies in the vicinity of the cluster.
Below is a picture of the centre of the A1185 cluster. It is probably the most important cluster in the Leo supercluster. This cluster is about the same size as the Virgo cluster and has a similar number of galaxies. The brightest galaxy here (at the top of the picture) is NGC3550.
