All these showpiece nebulae in a single image!

They lie in the Large Magellanic Cloud. But beyond that, for better or worse, most of these Nebulae have little substantial information in popular literature.

This region obviously hosts very active star birth—the illumination of the clouds, both the blue reflection nebulae and red emission nebulae attest to this, along with the bright, young-star clusters NGC 2011 and NGC 2014. Strong stellar winds accompanying young hot stars' formation push the gases into shells, loops, and streamers. Some young stars are giants and have short lifespans, ending in supernovae, while other stars just begin their lives. The supernovae form structures such as those that dominate in NGC 2040 and, likely, NGC 2020.

Processing: This image is a “True Color” rendering. The narrowband images bolstered the R (H-alpha), B (H-beta), the blue-green (OIII). A synthetic luminosity, constructed by L=4H+4O+R+G+B, reveals and visually strengthens the structures.

To this point, most of the operations were on starless images. Further processing took advantage of artificial-intelligence image-processing tools to adjust the dynamic range, emphasize structure, tweak color contrast, etc.

A separate RGB image, photometrically calibrated, provided the stars returned to the starless image for a few more refinements.
