Finding the Andromeda Galaxy

The illustration shows the orientation of this group of stars setting in the western sky after dark in January. In the center is the Great Square of Pegasus, the Winged Horse. His head hangs down to the globular cluster labeled M15, very near to or below the horizon. At the top of the Great Square is the alpha star of constellation Andromeda. The trail of stars heads up past a faint pair (colored yellow), past the beta star to gamma Andromeda at the top (both pink). Gamma is an attractive double star of contrasting colors when viewed with a telescope. On a clear, dark night you should be able to find, without telescope or binoculars, the smudgy streak of the Andromeda galaxy M31 to the right (north) of beta Andromeda. Another route to this galaxy begins at the north star Polaris. From it, go straight through the "W" shape of constellation Casseiopia and about 75% farther. You will be in the Andromeda galaxy neighborhood.
