Ironically its not scientifically accurate due to non linear stretches. Perhaps you could do a negative linearly stretched version and superimpose the RGB galaxy over the top. In any case, its a great image. Well done.

Thanks Jase. Yes definitely there are several ways to work out on faint details. Actually, when details are really barely visible on the original image is when things become tricky. I also recently purchased Pixinsight and I am experimenting with some of its routines, same for CCDStack. Perhaps I will be able to find other ways to squeeze out the original data. For sure this is the most stretched image I have ever produced, I usually don't like to go so extreme but I wanted to try something out of the common path on this very popular subject. Superimpose the RGB galaxy over the negative stretched data is the way Mike chose for his excellent shot, it is definitely a nice way to go and perhaps more "scientific" but I am still intrigued to experiment something different, at the end of the day my target is to have a pleasant image, with real details but not necessary scientifically accurate. A simple DDP is already producing a non scientifically accurate image, let's apart working on colors or adding narrowband images
