I integrated the data using 2x drizzle and did a tight crop to zoom in on the nebula.
Seeing was not the best and it was one of those nights, were guiding was driving me crazy.
For the channel combination i used the NBRGBCombination script in PixInsight. Postprocessing was mostly done in Photoshop.
