M38 open star cluster, sometimes referred to as the Starfish cluster. M38 is the upper cluster. The slightly tighter packed cluster to the bottom of the image is NGC1907.
A popular star cluster is NGC 457. It has numerous names, such as the Dragonfly cluster, Owl cluster, E.T. cluster, no doubt many other names as well.
It is the brightest cluster in the circumpolar constellation of Cassiopeia. Circumpolar meaning it never drops below the horizon from our view point here in the UK. Which allows us to enjoy this beautiful cluster all year round.
