Alpha Persei, Mirfak (The Elbow) or Algenib (The Side), although this latter name is also the designation for gamma Pegasi.

This particular region of the sky is very rich and a marvelous sight in binoculars.

Mirfak is one of four stars which form a circular line around Cassiopeia. First find Cassiopeia then locate the three stars in Andromeda. Further along this outer group you'll find finding Mirfak.

Of course you'll have to adjust the graphic depending on where Cassiopeia is found.

Once you've located Mirfak, you'll easily discover Algol (beta Persei) by moving away from the Pole Star (that is, due south) about ten degrees.

Mirfak is in the same field as a number of other bright stars: binoculars.
