Yes, a galaxy is a cluster of millions of stars orbiting a central black hole or other gravitational anomaly. A consellation is a minor arrangement of stars (more than 3, less than 40) as viewed from one specific direction which mimics the pattern of an earthly or cultural object or image. A galaxy is a galaxy no matter how you look at it. A constellation only exists when viewed from a specific angle and range of distance.
