The Forax Narrowband Palette

In this video I show you how to use dynamic Pixel Math expressions in PixInsight to produce a narrowband palette based on your data to produce something other than just a standard SHO or HOO image.

If you are interested in learning more about the dynamic Pixel Math expressions, here is the link to a fantastic write up by Forax himself:
