Astroarts StellaNavigator
Cassiopeia was the wife of Cepheus, the Ethiopian king, and the mother of Andromeda. The asterism clearly shows the chair upon which Cassiopeia sits. It looks like a shape of "W", and is a guide to find out the Polar Star like the Big Dipper. Japanese had given the asterism names of "The stars of Anchor" or "The stars of shape of mountains", and so on.
The constellation is bathed in the faint autumn's Milky Way, so includes various nebulae and star clusters.
