Description:
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).

[SII]: 9x600"
[OIII]: 18x600"
