Sh2-9, also called Gum 65 is a combination emission and reflection nebula in the Scorpius constellation, surrounding the multiple star system Sigma Scorpii.
This image combines Ha data from my light-polluted suburban location & LRGB from my buddy Blue's dark site in rural Victoria, Australia.
I was surprised by how much dust is present in this region, which doesn't appear in many other images, and I've attempted to balance this LUM dust with the Ha signal, while letting blue giant star Alniyat reign supreme
