Description: A mind-blow cropped detail about ACO 2197 Galaxies group region in Hercules with focus on NGC6180, NGC6175, NGC6174, NGC6173, NGC6160, NGC6160, NGC6146, NGC6147 and NGC6145.

ACO 2197 is part of the great wall of galaxy clusters which includes the Coma Cluster (ACO 1656), the Leo Cluster (ACO 1367) and the Hercules Cluster (ACO 2151). It lies only a short distance on the sky, about 1.5 degrees, from ACO 2199 and there is evidence of a filament of galaxies linking these two clusters with ACO 2151. ACO 2197 and 2199 along with 2151, 2152, 2147 and 2162 comprise the Hercules Supercluster.

The brightest three galaxies in the cluster, NGC 6160 (121.5 Mpc or 396.1 Mlyr), NGC 6173 and NGC 6175 were all discovered by William Herschel in 1787. At the same time Herschel also found the fainter galaxies later catalogued as NGC 6146 and NGC 6150.
