The group Hickson 61 consists of 4 galaxies. Only three of them - NGC 4169, 4174 and 4175 are about equidistant. NGC 4173 is far in the foreground with only 50 million light years distance. NGC 4174 could be a polar ring galaxy, because there is a large structure exactly perpendicular to the galaxy disk.NGC 4131, 4132 and 4134 on the right of the image have similar radial velocities to NGC 4169 and co, suggesting a very similar distance.
