A long time coming, a new PixInsight tutorial has been finished. This one is on a subject many have asked me about for over a year - Narrowband Hubble Palette. To date, my tutorials have only covered how to make bi-colour narrowband images but not Hubble Palette narrowband images, despite me having made several of my own. The omission is now rectified with the addition of this new tutorial, which you can read by following this link.
