Finally got to a dark site this new moon for a couple of nights.
I collected RGB and Ha narrowband data and I am presenting the combined HaRGB image.
Presented this target as an RGB only image here
Cocoon Nebula RGBHaRGB processing in PI, using the RC astro tools, BlurX, GHS, StarX for each layer, and separate star layer SPCC for color calibration, and NoiseX.
Lots of curve work, darkstructures enhance, advsharpening, layering of Ha and RGB images, and screened the stars back in, final tweaks in image editor.
Thanks for looking!
Clear Skies

IC 5146 (also Caldwell 19, Sh2-125, Barnard 168, and the Cocoon Nebula) is a reflection/emission nebula and Caldwell object in the constellation Cygnus. The NGC description refers to IC 5146 as a cluster of 9.5 mag stars involved in a bright and dark nebula. The cluster is also known as Collinder 470. The cluster is about 4,000 ly away, and the central star that lights it formed about 100,000 years ago; the nebula is about 12 arcmins across, which is equivalent to a span of 15 light years.
When viewing IC 5146, dark nebula Barnard 168 is an inseparable part of the experience, forming a dark lane that surrounds the cluster and projects westward forming the appearance of a trail behind the Cocoon. (wikipedia)
