OK, got most of this Mono processing working but I need to understand how and at what point do you combine the Ha image to the RGB.
My current process is to align the RGB and Ha images in the layers step then crop and save. Then re-open that and copy each layer into it's respective channel finally copying the Ha layer to the red channel over the already copied red layer.
Is this the correct or preferred process or is there other\better methods or options to try ?
