The Rosette Nebula, NGC 2237, is a large and amazing HII region located in the Monoceros constellation. The nebula lays some 5.000 light years away from us and measures 130 light years in diameter spanning over 5 times the angular diameter of a full moon.
In the core of the Rosette Nebula can we find the open cluster NGC 2244, composed by hot young O-type stars that sculpts, with its strong winds and radiation, the entire nebula creating this characteristic and aesthetic shape. This region evokes imagery of several African animals.
This image, with a total exposure of 13.5 hours, is the result of combining narrow band data, with the use of [SII], Hα and [OIII] filters, with broadband data, to give a natural color to the stars with the use of R, G, B filters.
To better show the emission data that comes from this active star forming region, a variation of the HOO palette has been used to enhance the entire structure of this nebula. The percentages used to compose this image have been:
RED channel: 30% [SII] + 70 % Hα ; GREEN channel: 20% Hα + 80% [OIII] ; BLUE channel: 20% Hα + 80%
The star’s colors come directly from the use of broadband filters (R,G,B).

Support my work. If you want to help me continue with my work, please feel free to buy, just for a few pennies, one or several of my images. The price does not reflect the amount of effort involved in each one of the images. Some of them implied weeks, months and even years of hard work. With your purchase I will be able to continue capturing photons of our amazing universe.
