M106, also known as NGC4258, is the big galaxy at the left part of the image. It is a barred spiral galaxy in the constellation Canes Venatici. M106 is about 22 to 25 million light-years away from Earth. It is also a Seyfert II galaxy, which means that due to x-rays and unusual emission lines detected, it is suspected that part of the galaxy is falling into a supermassive black hole in the center.
NGC4217, at the right part of the image, is an edge-on galaxy lying only 30 arc minutes southwest from M106. It is 12th magnitude.
These 2 galaxies and many other much smaller that can be observed on the background of the image are part of the Canes II group or Canes Venatici II group, which is a group of galaxies about 26.1 million light-years away from the Earth. The group resides in the Local Supercluster. The largest galaxy within the cluster is M106.
