Thanks Peter and Rob. Stacking the captured data was done the traditional way using DSS and then image stretch and denoise in StarTools. Most of the work was done in Photoshop bringing in the Ha data to scale and rotate to fit the RGB widefield using Layers. Due to the fact I was only enhancing the nebulous areas with the Ha data, I just had to use small areas of the image to register the stars in M8 and M20 to fit manually. To be honest, the RGB background stars collected with the DSLR aren't the greatest quality but it was the easiest and quickest way to capture it before predicted clouds moved in. All in all, just another experiment on shooting techniques anyone can use with a bit of innovation. Good to think outside the square, it gives my aging brain some thought provoking exercise!
