M106 is a spiral galaxy 30 kly across and 21 million ly distant. It is the closest example of Seyfert galaxy. Seyfert galaxies have active core emitting huge amounts of energy across the spectrum. Such active cores are believed to be fueled by matter falling into massive central black hole.

NGC4248 is a dwarf companion galaxy of M106, some 82 kly distant from it.

NGC4217 is an edge-on spiral galaxy visually close to M106. But, at 55 million ly it is much more distant than M106. Its prominent central dark dust lane is clearly visible in the image.
