The Rosette Nebula, a star forming region in the constellation Monoceros, located about 5,000 light-years away from the Earth
H-alpha narrowband image
Image Integration: 4 hours
In the middle of February 2019 I had acceptable astro-weather. The only problem to start with a bigger imaging project was the strong moonlight. I decided again to make a narrow-band image, this time about a beautiful spherical H II nebula and star-forming region located at the southern part of the night sky in the constellation Monoceros about 5,000 light-years away from Earth. 4 hours of exposures through the 12nm H-alpha filter allowed to capture some very faint details with my 8" telescope.
I prepared a star-less version too, to show the internal morphology of the ionised hydrogen dust clouds. These images have special artistic touch but still represent scientifically correct informations. The filaments of the dark nebulae mixed with the strong emitting bright dust clouds form several abstract shapes and excite the human imagination.
