I'm interest in how you blended the narrow band info with LRGB.
Do you know if you can do this with PI ?

Hi Chris I blended the LRGB to the SII Ha OIII via lighten mode with an opacity of around 46% so that I got the RGB stars. I then blended the OIII to the blue channel (just to enhance the blues) and the Ha went to luminance (this was for detail which I sharpened a lot in some areas just for that purpose). Each with varying opacity (its all about how it looks). The important thing to remember is not to let the Ha dominate too much and produce salmon colours (not an easy task and I am unconvinced this is the right colour scheme, but it look ok). It took some fiddling to get right or close to being what I wanted. Prior to the blend I worked on a combined image of the narrow band data. Essentially I got the NB looking correct first before attempting any of the blending.
I don't use PI, so I could not tell you that if PI would do the same but I imagine it would do that. Someone with PI experience would certainly have the answer for you.
