Overview
CWNU 1500 is a sparse, very dense object of high C3 quality. Its parallax locates it at a relatively close distance, above the mid-plane, affected by high extinction. It is catalogued as a metal-rich, very young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It was recently reported in the literature.
