Description

Everything was working so well last night that it almost felt like cheating. I was able to grab 2.4hrs of exposures painlessly and before midnight, at which point the subject moved behind the neighbors roof.
I present to you NGC2237, otherwise known as the Rosette Nebula.
From Wiki:
The cluster and nebula lie at a distance of some 5,000 light-years from Earth and measure roughly 50 light years in diameter. The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. The mass of the nebula is estimated to be around 10,000 solar masses.
