Absolutely breathtaking.  It is something I just keep coming back too,
the more I look the more I see.  Different sources define M11
differently, some say globular cluster and others say open cluster.
It is very loose if it is a globular, more like a dense open cluster.
SEDS website gives it a diameter of 14.0', but I really think it is
almost double that.  The main body resembles a square.  It is
dominated by an 8th magnitude yellow star slightly off center.
Doesn't remind me of a flock of ducks.  More like a sprinkling of
salt on a black background.  There are three dark areas, like bubbles.
One bubble is on the east side in the center of the east edge of the
sqare.  The west side has two, one in each corner, connected.  There
is another dark lane snaking from the east bubble to the north edge.
Outside the box there are innumerable stars.  This cluster just give
more stars with each new eyepiece.  Absolutely spectacular.
