Cygnus is a prominent easy-to-find constellation in the northern hemisphere sky. That contains the northern cross asterism and which is itself part of the Summer Triangle asterism.
Cygnus or the Swan is said to represent the bird into which, Jupiter once transformed himself while on a secret visit to the Queen of Sparta.
Technically you don't need any equipment at all to see Cygnus! However, to see the fainter stars in the constellation, especially from a light-polluted location would require a good pair of binoculars.
