HINT

This photo contains two major constellations – one soars through the high, northern summer Milky Way. Its asterism is also well-known.

The other sings songs of the Greeks on the strings of this harp-like instrument and contains both a famous "double-double" and a planetary nebula.

Both constellations sport first magnitude stars. (One ranks as the fifth brightest looking star.) Both stars form a triad with another that makes a large seasonal asterism.
