The North American Nebula (and Pelican Nebula) is an emission nebula in the constellation Cygnes. This area is literally glowing with emission nebula. In visible light, this would mostly appear red. However, I captured this with narrowband filters, using my new camera which is mono which I explained here. This is actually a bi-color image. It’s more common to use 3 channels (Ha, Oiii, Sii). But this is just Ha and Oiii. Red=Ha, Green= Oiii, Blue = Oiii, then while processing some colors are brought up, others brought down to get the colors I want.
That is what is neat about astrophotography. There is a lot of science involved, but there is also some artistic freedoms, especially with narrowband imaging.
