Description

Much dust in this region, it was really hard (for me) to not oversharpen the fine details. Again I went with keeping the greens in the outer nebulosity and using Color Masks in Pixinsight to carefully mask the wanted regions. Mapping the colors with Pixelmath was a straight 100% SHO combination.

Hope you like it :-)
