Some say it’s the Rosette Nebula; others say it’s the Flaming Skull Nebula – no one knows why, but we can agree it’s NGC 2237!
Amazing thing Pareidolia; once you’ve seen the skull, you can never unsee it!

Here is my take on NGC 2237 in HaO3LRGB from a dark site in rural Victoria, Australia, using Voyager.

About this Nebula

This vast emission nebula lies about 5,200 light-years distant in the constellation Monocerous.
Also known as the Satellite Cluster, NGC 2244 appears in the nebula’s centre; these hot young stars were formed from the nebula’s material in the last 5 million years.
The stars in the Satellite Cluster are responsible for the nebula’s glow as their radiation ionizes the surrounding clouds of nebulosity, causing them to emit their light.

Thanks for looking. Can you see the skull too?
