Processed in PixInsight, with only mild noise reduction.

In my opinion the best noise reduction is, and probably always will be, to collect more data. The integration time needed to reach a certain SNR level increases with light pollution. It is said that for every magnitude you lose due to light pollution, you need to multiply your integration time by 2.5 in order to reach a certain SNR.

In this image I applied just enough noise reduction to reveal structures in some of the fainter dust. I then used a masked stretch to enhance the weak stuff even more. I think that to do this target justice, under your skies, you need to spend at least 20 hours on it.

I think Photoshop is the world's leading graphics program for good reasons. Of course it isn't astro-specific and, like you, I cherry-pick some PI routines, but Photoshop's genius lies in its user int

I quickly did process of that no filter version and here is what I came up with: Now, I did not mess with saturation and all that - just basic levels and some noise control. This was d
