Thanks.
I have been mapping Ha to Green as to what I thought was the Hubble palette. I have also been turning it way down so that it does not overwhelm the image.
What is your interpretation of the Hubble palette?
Have been looking at other colour mapping to Ha, SII and OIII. Colour is very subjective (it seems) and comes down to taste.
I could bring the blacks up a bit, but it does show a bit too much noise and tends to detract from the image. I did go on the assumption that space is black...
