Deep-Sky Object Classes Dataset

The taxonomy of astrophysical object classes, including the deep-sky classes added by the Deep Sky Objects Encyclopedia (open & globular clusters, stellar associations, the emission/reflection/dark nebula subtypes, HII regions, Bok globules, planetary nebulae, supernova remnants) alongside the compact-object, AGN and large-scale-structure classes. Only well-established astrophysics; nothing fabricated.
