Well....bloody brilliant I recon
While I think selectively applied basic sharpening could enhance some of the high signal areas, it is also not imperative to do this either. No probs re the handling of the stars, a perfectly legitimate approach there and not only is the whole image aesthetically pleasing but the colour palette (in fact the whole image) makes perfect
sense and shows the distribution of the three wavelengths nicely, just the right amount of saturation too... ie the right balance between science and art to me.
An attractive, believable image of a famous nebula, well done.
Of course if you get the bit to the right of this mosaic now, it will be a nicely balanced image
