Description

This is my first attempt to these popular targets. I have shot it in three different nights - July 15th, 26th and 27th.

A complete new processing workflow for me, since I've split the RGB channels during pre-processing in order to run NGS but instead of recombined them, I've followed a NB workflow. 
Channel combination followed Foraxx's tutorial at  https://thecoldestnights.com/2020/06/pixinsight-dynamic-narrowband-combinations-with-pixelmath/, which I found very suited for these targets, as it allowed to naturally enhance the blue shell at Crescent Nebula and the Soap Nebula as well.
Stars are RGB, shot at Aug.18th with a simple LRGB filter (10 x 120s) and its chrominance blended using a star mask.

All in all I think its a reasonable result, which I hope you enjoy. All comments and constructive criticism are welcome.

Clear skies,
André
