This image was taken to determine if there were suitable HII regions near the stellar association NGC206 in the Andromeda Galaxy for further hydrogen alpha exposures. Indeed, I was not only surprised at the number of small and structured regions, but also that many of them are intimately associated with the hot blue OB stars, often forming arcs and sheets in their immediate vicinity.

The colors seen in this transitional region of the arms are interesting. While the sunshine yellow core is way off to the lower right off the frame, we are moving into a very obscured portion of the disk, riddled with dust and transitioning into blue arms to the upper left. Thus the browns and ruddy disk leads into strikingly sky blue colored OB stars.
