The image is processed in HOO palette , This was a real challenge as I make the session in Cairo , Bortle 9 . I did a lot of trials to remove the light pollution effect and background extraction then many masks to sharpen and enhance the colors in the nebula.

Kindly find my image for SH2-275 " Rosette Nebula".

The nebula is an H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky way galaxy. Its far away from earth by 5000 light years and has a diameter of 130 light years so it’s a real monster in the sky. 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 mass.
