The North America Nebula (NGC 7000) and the Pelican Nebula (IC 5070 and IC 5067)

Thank you! Bicolor is the combination of only hydrogen and oxygen. The Optolong L-eXtreme filter captures in both ranges at once. In the red channel, you get hydrogen, and in the blue and green channels, oxygen. For a color camera, the image is first split into channels, as if it were shot with a monochrome camera, and then the rest of the process follows. For the Hubble palette, sulfur is missing; in this case, it is simulated using the luminance channel.

There are various videos on YouTube. Several stacking variations, but for PixInsight. I haven't looked for ones for Photoshop. And I don't know of any in Russian.

Plus, it seems this method isn't suitable for all objects. Since it's shot with a color camera, the oxygen signal is quite weak. I tried processing the California Nebula this way—it didn't turn out as a striking photo; the hue changed, but no oxygen is visible on the side of the nebula. I also tried it on M16, the Eagle Nebula, and it didn't work either, though I have relatively little total integration time on that target. I haven't tried the Heart Nebula yet.
