NGC 6888: The Crescent Nebula
Full write-up here: theastroenthusiast.com/ngc-6888-the-crescent-nebula/
This is another image from telescope live: the Crescent Nebula. It was a tough dataset to stack, as there were a bunch of dead pixel lines from the CCD. However, once the dataset was stacked, it was quite fun to process. The Oiii data was extremally strong, and it was really interesting to see the extent of the wispiness around the nebula. I’ve been experimenting with a new “natural” pallete made from SHO emissions, and I think it turned out pretty accurate!
NGC 6888, also known as the Crescent Nebula, is a cosmic bubble about 25 light-years across, blown by winds from its central, bright, massive star. It combines a composite color image with narrow band data that isolates light from hydrogen and oxygen atoms in the wind-blown nebula. The oxygen atoms produce the blue-green hue that seems to enshroud the detailed folds and filaments. 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.
