Nighthound: I use DSS all the time. I don't think it is clipping the dark points. It's too easy to clip away unintentionally in PP, especially when you're trying to over compensate for noise and or LP. I'm guilty of the same.

I'm trying to hone my PP skills, learn and grasp "overclipped" here.
When I look at both picts the RGB values in "black" are not zero, they are 8-13 over what appears just black space, meaning not true black (0,0,0) therefore some data still there, correct?
That shows there is some image color left in there, at least on the pixel you have selected.
Take a look at the histogram, especially as you're processing.
I hope you don't mind, According to your profile you allow image editing. Unfortunately there isn't much you can do with a jpeg that has already been cooked. What original image data that was there is no longer there, at least not like it was.
But here is a copy of your first post that I edited. It's exaggerated and probably too bright for some peoples taste, and, the quality sucks because I had to reduce it so much to get it down to 150kb or less to attach to this message.
Nevertheless, I think it demonstrates where the image data was clipped revealing where some of the Dust and nebulosity is throughout that whole area. Such as the dark dust and nebulosity that can be seen below the Orion and Running Man Nebulae, as well as the blue reflection nebula at the very top above the running man that was completely clipped away.
I can only imagine what could be done with the unedited stack.
