This cluster is framed so well by the background stars.  I wrote down that it was
easily 45' in diameter, it filled my 13mm nagler at 109x, but SEDS puts the
diameter at half that.  This was the first time I saw this cluster with my
ten inch.  It reminds me of the first time I saw M11 with an instrument of any
aperture; very beautiful and round, a black background sprinkled with salt.  There are 2 m20 like dustlanes  crossing through the center.  At the cross
is a red star.  It sounds like an old open cluster cliche, but it really is reminiscent
of a ruby in a pile of diamonds.
