Thanks for that suggestion. Maybe I went too far with
the star shaping... I'll go back a few steps and see
what happens.

I think that I'll have enought time to do that in the
weekend... Anyway, basically it is just the same as I
did with previous images: first SCNR to get rid of
that green noise, then A Trous Wavelets for the high
frecuency noise, RRL deconvolution (masked with the
luminance), and finally SGBNR for the large scale
noise. SGBNR was applied two times. First in a "LRGB"
mode (I extracted the luminance, and applied SGBNR to
it, and then SGBNR to the RGB image without much care.
Then I imported the L channel and the definition was
recovered). The second one was in the Lab color space.

I'll upload some process icons I used so you can load
them with PixInsightLE and see directly what I did to
the image.


Regards,

Carlos
