If there had not been the "Included in" link in the explanation to the APOD of April 25th 2009 I may not have known that the image showed seven Barnard's nebulae, as I thought what seemed like one dark band was one Barnard nebula. Mind you, I'm not sure why B10 is one as it seems too bright to be a Barnard nebula.
