Fourth time is the charm? Another attempt to image this bright but complex nebula that looks like a red brain wrapped in blue gel.
The vastness of space displaced in the space / Of a nebulous brain with an invisible face / Both explosion and implosion as the stellar winds blow / From a Wolf-Rayet star with a nuclear glow / Its membrane stretched thin: what will the fate / Be of this structure named NGC6 triple-8?
This is a long focal length (1645mm) capture of the Crescent Nebula using a narrowband filter to enhace the detail.
A close-up of the Crescent Nebula. NGC6888 is the expanding shell of an ancient supernova with supercharged dust particles that glow from the energy of nearby stars.
I usually image NGC6888 at a high focal length for a closeup view. This nebula that is apparently fashioned after the human brain is itself located against a backdrop of faint nebulosity. 2 hours is probably not even close to enough total exposure time for best results, but here's the Crescent Nebula so far...
