North is up in this image. The two central galaxies that dominate this image are NGC 3169 (left) and NGC 3166 (right). These are part of a galaxy group named the NGC 3166 Group. Other members in this image are NGC 3165 and NGC 3156 - both lower right of the large pair. There are several other notable galaxies in this image that are not members - they are either foreground or background. One of those galaxies is the KARA Dwarf, PGC 29873. Also in this field are a number of Quasar objects; most are too small or dim for this image scale since they are at large distances from Earth. But some are detectable and are identified in the annotated image. NGC 3166 and NGC 3169 are estimated to be about 54 to 71 million light years distant. These objects and some of the bright stars are identified in the annotated image. Horizontal FOV is 85'
Image center is approximately - Equatorial 2000: RA: 10h 13m 48s Dec: +03°26'00"
