Rosette Nebula in H-alpha (with a color camera)
-----------------------------------------------
A large cloud of gas and dust which lies near the Monoceros molecular cloud.
The nebula is a region of active star formation.
The hot young stars of the central cluster of the nebula emit intense radiation in the form of stellar winds, ionizing the gas of the nebula which then re-emits this radiation (creating the emission nebula).
As the predominant gas of the nebula is hydrogen gas, the main radiation that is re-emitted from it is at the hydrogen-alpha wavelength.
This is around 7 hours of H-alpha data I was able to capture earlier this month.
The H-alpha data came out quite good and needed minimal processing (even though I shot this with a colour camera), so I thought I would share this.
