The incidence of a reflection nebula and the presence of quite heavy dust clouds around Tarantula will in my opinion at least, tend to darken both the reflection nebula and the emmission nebula quite some.
The other thing worth remembering is it is your image and your representation of the chosen target. As long as you are happy with the result that is realy all that matters. People like myself only give you an alternative representation of what we believe the target to look like, right or wrong we will never know but it is just another take on the same image.
The other reason for the rework or reprocess is an attempt to pass on methods we use to achieve our end results. Whether you use it or not is up to you as an individual. It is your image after all.
Keep up the good work.

Totally agree with all that you say above Doug. I like your colours too. At the end of the day that's what the processing is about. Making a visually pleasing image. What I've always been wondering is what the "original colours" should look like. As Peter Ward posted once, we don't want to shoot in broad day light and found out that people have green skin tones. Then you know that the RGB ratios 1:1:1 are wrong. I wonder what ratios other QHY8 users use when doing RGB.
Regarding the QHY8 I know that it has twice as many green pixels as the two other channels. So what ratios would you use? Also have you found that shots around the Tarantula always seem to be noisier than other areas of the sky? Is this because there are so many stars in the area?
