I'd be interested to know what methods people use in Photoshop (I don't use Pixinsight) for Ha highlights in galaxies.|
I sort of worked out a method to do it, by converting the Ha to RGB and then pasting LRGB over it, blend mode lighten and then increase the red on the Ha layer.
This sometimes it works OK but sometimes it doesn't, and it doesn't always produce a deep enough red either.
I'd be interested to know what Photoshop methods others use. I've tried googling it and all I can find it combining in nebulae rather than Ha highlights in galaxies.

usually i prefer PI to PS, but when adding HA in PS i use the following procedure:

after you have done what Fritz suggests, it may be that you also need to blend the Ha data into the luminosity layer. If the Ha occurs in discrete regions and there is very little Ha information in the luminosity, then it will hardly be seen in the final image. At least, that is how I think it works but then I have only tried this for nebulas…..

|Blending Ha into luminosity channel is obligatory. Otherway you cannot highlight Ha data!|
