Yes i have found data
do not worry.
Thank you, has been instructive. The great problem with pixinsight is to decide how to "attack" the image, there are so many possibilities.
For example i have never found information about MultiscaleMedian Transform (MMT) used for noise reduction, and usually i have applied noise reduction finally, never at the beginning before stretch. This is interesting, so you can apply more than one stretch after, without amplify noise.
In general i would be more soft
noise reduction is a little to aggressive, but HDRMT is too much soft
but this my opinion and a ground to start a new processing.
Just one question and a suggestion.
First, why have you done a ACDNR? the image appear to be soft also without this step, and why at beginning have you used MMT to reduce noise instead ACDNR?
Second, could be useful to create tutorial using "normal" images, in the site examples are about incredible images with a lot of signal where you can do everything you have in mind without worrying about noise. But with normal integration, more or less 5 hour is very difficult to find an approach to processing faint nebulas and dust.
