Messier 11 (also know as the Wild Duck Cluster) is one of the richest and most compact of the galactic (open) clusters. M11 is at a distance of approximately 5600 ly and contains an estimated 2900 stars, about 500 of which are brighter than mag 14. An observer at the center of M11 would see several hundred first magnitude stars!
