Cocoon Nebula (IC5146, Cropped) - a photo on Flickriver

The Cocoon Nebula is an emission nebula and star cluster about 4,000 light years away in the constellation Cygnus. The nebula holds a bright red emission nebula, blue reflection nebulae and dark absorption nebulae. The massive central star formed about 100,000 years ago.

I imaged this nebula with my William Optics FLT91, F68III 1x flattener, ZWO 2600MC Pro colour camera and both a broadband filter (Optolong L-Pro) and narrowband 3nm Ha & OIII filter (Optolong L-Ultimate). The total integration time was 3h18m.
Postprocessed in PixInsight and Affinity Photo2 with StarXTerninator, NoiseXTerminator and BlurXterminator.
