In PixInsight, there is a tool called HDRMultiscaleTransform. You can apply it several times as you stretch the histogram to avoid losing details in the center of the nebula. If you're interested, take a look at my Iris image to see how it works in practice. Your material has good potential!

Thank you. I'll try. But in your version, the BB is also not correct, and the background is red, not black.

But your photo has potential too, though I'm not sure what kind.
