Description: I reprocessed the data completely in Astro Pixel Processor! This time I extracted the OII and Ha channels and stacked them separately. Then I combined them in PixInsight via PixelMath (in the meantime I know how to do that with RGB-Combine in APP too. So, no need of PixInsight here either ;-) Finished, as usual, in Photoshop.
