The Cassiopeia constellation represents the boastful queen.
Cassiopeia is the wife of King Cepheus, and the mother of the beautiful Princess Andromeda. She was a vain, boastful woman who claimed Andromeda to be prettier than the Nereids, the beautiful sea nymphs.
This angered the the Nereids, and the sea god Poseidon(Neptune) who sent the sea monster Cetus to destroy the queen's land.
The king and queen were told the only way to save the kingdom was to sacrifice their daughter Andromeda.
Andromeda was left chained to a rock near the coast for Cetus but, before the monster could ravage her, she was saved by Perseus. As punishment Cassiopeia was chained to her throne and placed in the sky by Poseidon, where she spends half of her time hanging upside down.
Imagine her clinging to her throne in fear as she rotates around the pole.
With its distinctive “W” shape, once you locate the Big Dipper you should have no problem finding “the seated queen”.
Cassiopeia is opposite the Big Dipper asterism.

Messier Objects M52 and M103 are visible in binoculars. With an apparent magnitude of 7 they are quite easy to view.
Open clusters NGC457 and NGC663 can both be seen in binoculars as well, but a small telescope will give you more visible stars.
Cassiopeia contains several double, binary, and variable stars. However most are towards the dimmer side of the magnitude scale.
The four brightest stars though are all brighter than 3rd magnitude, making this constellation easy so see in general.
The Cassiopeia constellation is bordered by Andromeda to the south, Perseus to the southeast, and Cepheus to the north.
Also sharing borders with Lacerta and Camelopardalis.
