Once the images are gathered I processed each on individually by stretching the histograms so they were all more or less equal. Nebulosity has several useful tools for aligning and stacking each image. After processing I combine the images using the Hubble Colour Palette.
This maps the Sulfur image into the Red Colour Channel, the Hydrogen Alpha image in the Green Colour channel and the Oxygen III image in the Blue Colour Channel. The result is a nice colour image with the characteristic teal and gold colours of Hubble images.
