The Crater object is a faint star system, discovered relatively recently (, ), located in the Milky Way's outer halo. The collection presented here is based on optical imaging data of Crater taken with the on the Hubble Space Telescope. The available data includes the resulting catalog of Crater members, a catalog of artificial star tests, as well as an ACS reference image in F814W used for photometry. This study concludes that Crater is an unusually-young globular cluster (and not a dwarf galaxy), given it's location, though its origins remain elusive.
