Deep-Sky Objects API
The OpenNGC (NGC/IC) catalogue of deep-sky objects as an API — 13,000+ galaxies, nebulae and star clusters. Look up any object by its catalogue name (NGC224, IC434), Messier number (M31 → Andromeda Galaxy, M42 → Orion Nebula, M1 → Crab Nebula) or common name; browse the full 110-object Messier catalogue; or search by type (galaxy, planetary nebula, globular cluster…) and constellation. Each record carries the object type, J2000 coordinates (sexagesimal + decimal), V/B magnitude, angular size, surface brightness, Hubble morphological type, constellation and cross-catalogue identifiers. Ideal for astronomy apps, telescope planners, planetarium software and education.
