Thanks Greg and Adam. As a relative newbie, never underestimate my ability to confuse the more experienced folk with my simplistic image editing attempts
In this instance I used the Ha as additional luminance to enhance the detail but I'm aware there are better ways to integrate Ha with an (L)RGB image, I just haven't tried them yet. The Ha, by itself, provides a lot more background than I've managed to incorporate with my simple imaging editing techniques. Do either of you have a preferred technique for integrating Ha into an LRGB image? Alex
