The most commonly known story relating o this group of stars comes from the Greeks. Andromeda was the daughter of the King and Queen of Ethiopia. They are represented by the nearby constellations Cassiopeia and Cepheus. As the story goes, Cassiopeia, who was a very vain woman, bragged that she was the most beautiful living thing. This enraged the sea nymphs who sent a sea monster to punish the town. The only thing that would save them was for Cassiopeia to sacrifice her daughter Andromeda to the sea monster.
In the end, Cassiopeia relents and chains her daughter to a rock by the sea and leavers her to her fate. This time, though, fate was kind and before the sea monster could devour the girl, Perseus happened along on Pegasus returning from slaying Medusa. Perseus saw Andromeda and instantly fell in love with her. He slew the sea monster and carried Andromeda away to be his wife.
The Arabs saw this group of stars as a seal. But it is known most commonly as the maiden in chains.

Gamma Andromeda, Almach, I( 02h 04m +42° 20' ) s said to be one of the most striking star systems in the sky. Almach is a yellow K3 class star, 250 light years distant. Its magnitude is 2.3 Almach is actually a triple system, having two companions of greenish-blue companions of magnitudes 5.5 and 6.3. It is the contrast of the yellow and greenish-blue color that makes this system so beautiful in a telescope. Almach has a December 7th transit.

At a distance of 2.1 million light years, it is the most distant object we can see unaided. Seen without a telescope, the galaxy is about twice the diameter of the full moon. A small telescope will reveal a beautiful spiral shape.
