Astroarts StellaNavigator 		Perseus is a hero in the myth of ancient Ethiopian story; he rescued Princess Andromeda from the monster Tiamat (constellation of Cetus). He holds a sword in his left hand and a head of Medusa in right one. The asterism consists of plenty of bright and faint stars because of being just bathed in the Milky Way.
Beta Persei "Algol", that marks the Medusa's eye is a noticeable eclipsing binary system, changing from 2.2 to 3.5 every about 3 days. The name itself means "The Demon's head".
And the constellation is also famous for a major meteoric swarm, the Gamma Persei, it has the peak of appearance in the middle of August every year, you can appreciate from 60 to 120 meteors per hour.
