Levels and curves adjustments to stretch the images. Sharpening accomplished using several tools: smart sharpen, high pass filter. Several iterations of reduce noise filter. Combined using Cannistra's bi-color method to create a RsGB color image. Several iterations of Carboni action Make Stars Smaller. Shadows/highlights filter to increase nebula color.
