The big ball of stars near the center of this picture is globular star cluster M4.  Used the best 42 exposures of 180 seconds with the 200mm lens at f/2.8 and ISO 800.  Want to revisit this with M4 further to the right so we can see more of the dark dust clouds sticking out from the center of the Milky Way.  Shot on April 6, 2014.
