This is my version of the wellknown Rosette nebula, or NGC 2237. It is located just east of Orion in constellation Monoceros at 5 000 lightyears distance and it is about 130 ly in diameter. The bright stars in and around the nebula excites the atoms in the nebula gas, and this makes them shine as the emission nebula we see. The mass of the gas in the nebula is estimated to be around 10 000 solar masses. Studies of X-ray radiation images has shown that there are in the order of 2500 newborn young stars within the nebula area.
This is the first time I have used Pixinsight for image processing. Due to that, I did it in several versions and compared results with my normal processing routines. In my previous bi-color images I have
been having problems with bllue fringes on the stars, and in this case I have taken several measures to avoid them, such as reducing exposure time and processing the nebula data separately with stars removed.
