Description

Same data as the previous version, but trying to get something in the neighborhood of true color, and trying to incorporate the SII into an approx. true color version. It doesn't add a lot, since it's red like the Ha, but maybe it gives the tendrils a subtly different appearance.

Actually, true color seems to be a good deal more purple than this, probably I didn't try to simulate the H-beta signal by adding it to blue. But honestly I don't really like it being quite as purple as my RGB here (http://www.astrobin.com/130011/B/), so I am going to leave it 'approximate' in this regard. :-)
