This is a sketch of open cluster IC 4756 in Serpens made on September 16, 2012 with a 6″ F/5 dobsonian reflector. Very large cluster of stars near the pretty double Theta Serpentis. Some 30 – 50 stars were counted in the cluster which appears to have several concentrations of stars separated from one another by voids. the cluster fills the field at 75X.
