Description

I made quite a few changes to my processing steps. Firstly, I realised that I hadn't masked the dark areas before carrying out the saturation stretch - this led to the chromatic noise that was first evident.

Secondly, I used wavelets to carry out the noise reduction, rather than the ACDNR, I think this helped too.

Finally, I used 4 wavelet layers, rather than 6, in the HDRmultiscaletransform. This brought out more detail in the galaxy itself.

I think more to do still, but much better than previously.
