Description

Starting at the bottom:

Bright open cluster NGC 2581 featuring a red supergiant star toward its centre.

Right on top of that, NGC 3247 known as the Whirling Dervish nebula, in the bright area of that but hard to see without infra-red gear is Westerlund 2, another cluster only 1 or 2 million years old.

Right up the top of the image is NGC 3199 the Banana Nebula, the bowshock also from a (hard to see in this image) very large, Wolf-Rayet star travelling "up and to the right a bit" and pushing the gas and dust ahead of it.

Captured in a two-panel mosaic, Ha, Oiii and Sii filters assembled in H(S)O(H)O(H), about 25 x 600s subs stacked per filter per panel.
