I could _really_ use a simple (but controlable!) way of adding H-alpha channel to an LRGB image. Right now I'm having to use PI for this and it's anything but intuitive.

Re: [Ha]LRGB
Chris, you could make a synthetic luminance using the Ha blended with L (and, indeed, the R, G and B if captured at 1x1 binning, weighted by exposure). And/or you can blend it with the R channel prior to loading up in the LRGB module. Do this by loading the Ha channel, then opening Layers, then opening R and doing a 50% blend (or whatever weight is appropriate).
