Object name: HCG070
HCG 70 is a group of 7 galaxies in southeastern Canes Venatici. 3 of the galaxies are about 380 million light-years distant and 4 are about 850 million light-years distant so are really members of two groups. Hickson ignored distances when making up his list of compact groups. It was purely based on the visual impression much like Arp's galaxies were classified by visual impression rather than what was really going on. In both cases there just wasn't enough information at the time to take it any further. As for HCG 70, the two groups are made up of many more galaxies scattered around my image. Just that they were too faint or far from the center to be included in Hickson's group. There seems to be yet another group at about 700 million light-years in the field as well though I found no designation for any of these groups.
