Description

The Cocoon Nebula (IC5146) seems to be ploughing its way through a sea of stars. To me it was important to capture natural looking stars and at the same time reveal the faint details in the nebula.
Hence my approach collecting short subs for the RGB in order to preserve their colour.
I was planning on adding narrowband data to get some more detail in the nebula. To my surprise, there is plenty of S2 signal in the nebula, next to Ha as was to be expected. I couldn’t see any signs of O3, though. In the end I didn’t find a pleasing solution to integrating the S2 data, without making the image worse, so I went with HaRGB. I did not add Ha to the red channel, but used it as luminance.
