Data: mag 7.8 size 8'

Description:
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.
