Great picture! Note the little Cocoon Nebula in the lower left corner!

Also note the slightly diffuse "binary nebula" surrounding the hot highly luminous O-type runaway star 68 Cygnus. This fairly large nebula, almost as large as the relatively well-known Butterfly Nebula (seen in the upper right corner here) is located to the lower left of the North America Nebula.

THE CORE OF THE M31 ANDROMEDA GALAXY

Based on its appearance in visible light, the Andromeda Galaxy is classified as an SA(s)b galaxy in the de Vaucouleurs–Sandage extended classification system of spiral galaxies. However, data from the 2MASS survey showed that Andromeda is actually a barred spiral galaxy, like the Milky Way, with Andromeda's bar oriented along its long axis. M31 is known to harbor a dense and compact star cluster at its very center. In a large telescope it creates a visual impression of a star embedded in the more diffuse surrounding bulge. In 1991, the Hubble Space Telescope was used to image Andromeda Galaxy's inner nucleus. The nucleus consists of two concentrations separated by 1.5 parsecs (4.9 ly).
