Beautiful open cluster, very delicate, not bright and overbearing.  Near spiral galaxy NGC 6946 which is part of the Caldwell list.  This cluster is so close that I found it first and use it as a reference point to jump to the galaxy.  To be honest, the cluster is much more intriguing.  The sky was not so transparent at the time I looked at it, but ever other time I have seen it from a dark sight I find it breathtaking.  Definately a cluster worth revisiting.
