IC 1318 A in Cygnus

The Swan (Cygnus) is one of the most striking constallations of the summer night sky together with eagle and lyre. Its two bright star lines form a clearly recognizable cross in the sky, which is why it is also called the cross of the north. Through the swan is the bright ribbon of the Milky Way, which is why the constellation is particularly rich in stars and nebulous objects. In the region of the central star γ Cygni (Sadr), this image of a nebulous section of H-alpha structures was captured in combination of RGB images and bicolor technique. The second bicolor color channel was, however, not O[III] but S[II] in this case, since O[III] is virtually non-existent. The Bicolor mixture was combined with the RGB image, which makes the structures particularly vivid, while at the same time reproducing the colors quite realistically.
