After monkeying around with PixInsight, trying to figure out the best way to process my narrowband data, I finally found a recipe that’s repeatable, and I created a video to share it with other narrowband newbies. This isn’t a PixInsight tutorial–you need to already be familiar with PixInsight. But if you already know PixInsight, it’ll help you with how to combine three grayscale master lights (one each for H-alpha, SII, and OIII) into a single RGB image using the Hubble palette. I doubt there are any new tricks here for anyone who already has narrowband experience, but for newbies it might be worth a watch.
