Hmm... can I ask a question? Is this the same nebula that is often photographed together with the Heart? It's just that I usually see photos where the Soul and Heart are more reddish in color. I just googled it—there are images where they appear in blue and violet tones, while yours, for example, has more turquoise shades. So what color is this nebula really? By the way, the photo is gorgeous, but this thing with the different colors is a bit confusing :/
This is "Hubble's palette" in its pure form, meaning the narrowband signals from sulfur, hydrogen, and oxygen are assigned to the red, green, and blue channels, respectively. However, the actual colors of these filters are red, also red, and teal. If you mix them that way, hydrogen and sulfur would be nearly indistinguishable, and detail would be lost. So, every astrophotographer has their own approach to creating mixes, but generally, they are all equally distant from reality. It's just that there is essentially no green in the filters, and that color is typically removed. In reality, all these nebulae are quite unremarkable, and all the epic, vibrant colors are a result of Hubble photos, which were intended as scientific maps but ended up being more popular than the dull pink blobs in true RGB. Here, I simply decided not to remove the green—I personally like this particular nebula better this way.
Wow, there are so many nuances. The overall picture has become a bit clearer, but I'll read more about narrowband signals and the Hubble palette. At least now I know which direction to dig in ) Thank you so much for the detailed answer, it's very interesting. I'll say it again, your photo is amazing ) really, it's as if Hubble took it.
