RCW 58

I found this work not so easy to be done, but I really stoked into.
Mostly made in PixInSight I played and LRGB and HOO separated integration, background removing, Spectrophotometric color calibration.
I then used Ha to enhace both L and R channel, while Oiii to integrate G and B channel.
Extracting starless / stars masters,
then is adding stars from LRGB color calibrated master into HaL HaR OiiiG OiiiB nebula master.
This is a very interesting subject.
The central star in this image is WR 40 which is located toward the constellation of Carina.
WR stands for Wolf Rayet, in honor of French astronomers Charles Wolf and Georges Rayet.
This Wolf Rayet star is thus about 100 times as massive as our, lives fast and dies young.
It is going quickly to exhaust its core hydrogen supply, moves on to fusing heavier core elements, and expands while ejecting it outer layers via high stellar winds at a speed of nearly 100 kilometers per second, and these outer layers have become the expanding oval-shaped nebula RCW 58.
