NGC 6804 is a planetary nebula in Aquila, 2,300 light-years away
NGC 6804 (PN G045.7-04.5) is a planetary nebula in the constellation Aquila , 2,300 light-years away. It shines at magnitude 12.0 and spans 35″ of sky, about 0.4 light-years across. It is a telescope object, 6 inches or larger, and it is highest in the evening sky in August.
Planetary nebula: a shell of gas thrown off by a dying Sun-like star and lit by the hot core left behind, which becomes a white dwarf. The name comes from their small, round, planet-like look in early telescopes.
