NGC 6559, the other end of the Lagoon (7-1-2011)

Visually, this nebula does not appear to be linked to the Lagoon, but in deeper images the connection is pretty obvious.  This is more or less the other end of the same cloud.  Anyway, I like it for the nobbiness, the brighter slice of glowing gas at left, and the prominent dark river.
