The Omega Nebula, also known as the Swan Nebula, (catalogued as Messier 17 or M17 and as NGC 6618) is an H II region in the constellation Sagittarius. It was discovered by Philippe Loys de Chéseaux in 1745. Charles Messier catalogued it in 1764. It is located in the rich starfields of the Sagittarius area of the Milky Way.
The nebula is between 5,000 and 6,000 light-years from Earth and it spans some 15 light-years in diameter. The cloud of interstellar matter of which this nebula is a part is roughly 40 light-years in diameter and has a mass of 30,000 solar masses.The total mass of the Omega Nebula is an estimated 800 solar masses.
It is considered one of the brightest and most massive star-forming regions of our galaxy. Its local geometry is similar to the Orion Nebula except that it is viewed edge-on rather than face-on.

This is a total of 6 hours over 4 nights: 2 hours each SII, Ha & OIII.
Working in Narrow Band (False Colour as some call it) - one can indeed experiment with the colours. Here is another look at the same data - just shifted the Hues without any real re-processing:

My apologies........I should learn to always put the info in with the shot.
For this one:
Imaging telescopes or lenses: Takahashi FSQ106ED
Imaging cameras: ATIK 460 EX Mono
Mounts: Takahashi EM 400 Temma 2
Guiding telescopes or lenses: Takahashi FS 60 CB
Guiding cameras: QHY CCD QHY 5 II
Software: Pleiades Astrophoto PixInsight , Stark Labs PHD 2, Sequence Generator Pro SGP
Filters: Astrodon SII 3nm, Astrodon OIII 3nm, Astrodon Ha 3nm
Accessories: ATIK EFW2, Robofocus Focuser
Resolution: 2230x2065
Frames:
Astrodon Ha 3nm: 6x1200"
Astrodon OIII 3nm: 6x1200"
Astrodon SII 3nm: 6x1200"
I should add, for those not familiar, that I have my set up in SE Spain. That might sound great but in this instance, the humidity in the air made the seeing quite bad (background city/town lights glowing in the sky).

Added another picture version to the original post.
Just having fun working with narrow band......there is so much one can do with the data.
Brendan.

Hi Brendan where in Spain are you based?
