Nice work, Ian.
You've solved one mystery for us: what lies beyond the faint nebulosity behind the gem cluster (below left of centre). You've shown both how it interconnects with the Gabriela Mistral nebula, and how it overlaps a huge ring-shape at the bottom left of your image. (I'm guessing that the superposition of the gem cluster is just a line-of-sight thing.) So now, we know. Thank you.
