Hello!

Cassiopeia, "the Queen" comes from the Ancient Greeks. She is associated with the Perseus Myth.
Queen Cassiopeia was a very vain and boastful person, and was always getting into trouble. One day, she went too far and dared to boast that her daughter Andromeda was more beautiful than all of the daughters of the Sea God Poseidon.
The Sea God decided to punish the Queen, so he sent a sea monster (named Cetus) to attack the coast of the King’s country. The monster defeated the King’s navy, sunk his ships, and destroyed his port cities.
King Cepheus, not knowing what else he could do, appealed to the oracle of the gods for help. He was told that the only way to makeup for Queen Cassiopeia’s insults to the Sea God’s Daughters and save his people was to sacrifice his own daughter, Princess Andromeda, to the sea monster. So Andromeda was chained to the rocks on a cliff to await the monster.
About that time, the Greek hero Perseus showed up. Some say he was riding – or – flying Pegasus, the winged horse. Perseus had just gotten thru killing another monster named Medusa, who’s hair was made up of snakes, and who could turn people into stone when they looked at her. (Perseus had slain her by using a shield as a mirror, and cutting off her head with his sword). Perseus was on his way home, carrying the head of the monster in a bag.
Perseus took one look at Andromeda, and fell in love. He flew over to the King and Queen and asked permission to marry Andromeda. They agreed, if Perseus could save Andromeda and the kingdom from the sea monster.
When the monster Cetus appeared, Perseus swooped down on it with his sword, and began fighting it. But he was only able to kill the monster by pulling the head of Medusa out from the bag, and turning Cetus to stone. Perseus saved Andromeda, and the King and Queen, and their country.

Star Pattern resembles the letter 'W', or 'M' depending on the season and time of night.

Cassiopeia is home to a number of large stellar 'OB' Associations. An O-B Association is a large, very loose form of an open star cluster consisting of young spectral type "O" and "B" stars. They cover large volumes of space, are loosely held together by gravity and have short lifetimes of a few million years.

To view a sketch of a specific OB Association:

All sketches were made with an 80mm refractor spotting scope using low-power eyepieces, with an amici prism giving a corrected field of view. To view the sketches of these OB Associations, select from the list below:
