Description

Omega nebula – M17 – Ha-HSOOne of the most difficult nebulae for me to develop – beautiful structures with a very bright center

I had to go through two sets of images – HSO at 240 to 300 sec (20x) and HSO 60 and 30 sec (60x) for the center of the nebula very rich in light OIII.

Then the core of the global image was replaced by the short duration image (by Pixelmath on mask).

Finally, the RGB stars (3x20x20sec) with the luminance of the Ha 60sec series have been added.
