Hi Jase,
glad I caught this one.... aaahhh, two
I like them both.
Pin point stars all around, good teal colour to the standard and good use of the Ha data to accentuated the details within and to the outer shell.
Very nicely incorporated.
I do like mapped colour if only for something completely different.
My favourite palette combo is Ha=R: SII=G: OIII=B..
But then again it depends on what ones eye finds appealing.
Good stuff!!
Rich
