- NGC 1545
NGC 1545 is an open cluster lying along the stream of the Milky Way in the constellation Perseus. With a visual magnitude of 6.2 and a diameter of around 12 arc-min, this cluster is easily visible in binoculars or a small telescope. It contains around 65 member stars, although the appearance of the cluster is dominated by a handful of relatively bright ones. The richness of this cluster is a bit lost in the background of Milky Way stars. The cluster is located at a distance of around 2500 LY.
NGC 1545 is thought to be physically associated with nearby NGC 1528, located visually at around a degree apart. This would make these two clusters a "double cluster" like the famous Double Cluster (NGC 869 and NGC 884), also located in Perseus. The two bright blue-white stars along the right side of my image are HD 26961 and HD 27084. HD 26961 is a magnitude 4.6 Class A giant at a distance of 313.6 LY. HD 27084 is a Class A subgiant with a magnitude of 5.46 lying at a distance of 243.4 LY.
