This image has captured a distant but extraordinary large scaled galaxy cluster of "Shapley 8" (Abell 3558) concealed in northern region of Centaurus.
The cluster is positioned about 3 degrees southwest from M83, a spiral galaxy in tail of Hydra.
By clicking on the button in the upper right corner of the page, you can switch to an image that has removed stars within the Milky Way galaxy.
Shapley 8 is a principal cluster of "The Shapley galactic supercluster" about 650 millions light years away, contains over 200 member galaxies.
The cluster has been classified "3" in richness class, has the most bright galaxies in all of Abell galaxy clusters.
So we can take the picture of Shapley 8 with only small telescopes.
The Shapley super galaxy cluster had been researched by an American astronomer Harlow Shapley (1885-1972),
and "discovered" as an independent super galaxy cluster in 1989.
