This image shows you two medium sized galaxies at the throat of the Big Bear (Ursa Major), a spiral one in northwest (upper right) has a number of NGC2742 and another one in southeast (lower left) is elliptical NGC2768. Both galaxies are paralleling with an interval of about 40 arc minutes, NGC2768 is conspicuous because the galaxy has bigger size and brighter nucleus. They're forming a small scaled galactic group, the distance is estimated about 75 millions light years.
At almost the middle of the two galaxies, we can detect an extraordinary far galaxy cluster of Abell 742. This image barely shows you some member galaxies look like grains of rice.
