The Rosetta nebula - NGC2237 - a great classic protagonist of the beautiful winter sky!
It's my first shot with the mono room on this beautiful and fascinating subject. I acquired more than 35 hours!
The Rosetta nebula is a hii region located in the unicorn constellation. At its centre is an open cluster labelled ngc2244 - the stars of this cluster emit ultraviolet radiation, which excites the nebula gas.
The photo shows NGC2237, NGC2244, NGC2238, NGC2239 and NGC2246.

I hope you like it!!! And we hope for a better year!
