The Perseus constellation lies in the northern hemisphere sky, next to Andromeda. The constellation contains a few deep sky objects such as the Little Dumbbell Nebula and is the location from which the Perseids meteor shower originates.
Due to the position of Perseus in the Milky Way this constellation is rich in stars and deep sky objects such as M34 and M76.
Technically you don't need any equipment at all to see Perseus! However, to see the fainter stars in the constellation, especially from a light-polluted location would require a good pair of binoculars.
