Description:
This naked eye cluster is a joy to observe and undoubtedly the best open cluster in Auriga and a favorite amongst observers.   Dozens of bright stars can be resolved.   Fainter white stars surround a red 9th magnitude star near the center of this cluster, adding to its aesthetic beauty.   A telescope and careful observation reveals several dark voids within the cluster, which are dust lanes of the Milky Way.
