I was never really happy with my earlier rendition of this field.
This re-work brings out the SII data better and..maybe..
has a NB palette a little more soothing to the eye.
That said while I find NB palettes in general, a little hit and miss.
However, some regions like Ara, better show their structures in narrow band, hence the re-work to tease out some more detail.
Hope you enjoy the view.
