Butterfly Nebula

A second pass on IC 1318 five days after the first, this time framed to bring out the wing-like lobes either side of Sadr that give the nebula its popular name, the Butterfly Nebula. At around 4,900 light-years, IC 1318 is one of the largest and faintest emission nebula complexes visible from Earth, and the extra integration time here helps pull more of the faint hydrogen-alpha filaments out of the wings.
