A
            beautiful bright open cluster with many colored brighter stars.
            A surprise was the blue nebulosity to the upper left, LBN 604
            which is part of a larager dark cloud of dusty material. The
            cluster itself is 7th magnitude and 12 arc minutes in size. An
            amazing field!
