Description

IC 5146 (also Caldwell 19, Sh 2-125, and the Cocoon Nebula) is a reflection /emission nebula in the constellation Cygnus.

Here is a version in cooperation with my friend Philippe Lamothe using his 14" RC.

The RGB was taken with the ASI 294 MC PRO, while some Luminance and Ha have been added using the Moravian G2-4000 camera.

The luminance layer results from a RGB uncolored + L + Ha. The color uses the RGB and the red layer has been enhanced using the Ha data.

I decided to keep medium contrast.

Hope you like this one.
