"NGC 6888, the Crescent Nebula, is about 25 light-years across blown by winds from its central, bright, massive star.The oxygen atoms produce the blue-green hue that seems to enshroud the detailed folds and filaments. Visible within the nebula, NGC 6888's central star is classified as a Wolf-Rayet star (WR 136). The star is shedding its outer envelope in a strong stellar wind, ejecting the equivalent of the Sun's mass every 10,000 years. The nebula's complex structures are likely the result of this strong wind interacting with material ejected in an earlier phase. Burning fuel at a prodigious rate and near the end of its stellar life this star should ultimately go out with a bang in a spectacular supernova explosion. Found in the nebula rich constellation Cygnus, NGC 6888 is about 5,000 light-years away." [1]
This was my first post-solstice project and was taken over 5 nights between July 10 and 16. At this time of the year the dark nights here (53 deg. N) are only around 3h. Between high cloud and satellite traffic around a third of the subs were discarded.
The image is narrow band with RGB stars.
