The New General Catalogue of Nebulae and Clusters of Stars (abbreviated as NGC) is a catalogue of deep-sky objects compiled by John Louis Emil Dreyer in 1888. The NGC contains 7,840 objects, known as the NGC objects. It is one of the largest comprehensive catalogues, as it includes all types of deep space objects, including galaxies, star clusters, emission nebulae and absorption nebulae.

NGC 225
NGC 225 is an open cluster in the constellation Cassiopeia. It is located roughly 2,200 light-years from Earth. It is about 100 to 150 million years old. The binary fraction, or the fraction of stars that are multiple stars, is 0.52. At the 2022 Eldorado Star Party amateur astronomer Will Young, a member of the Astronomical Society of South East Texas, dubbed this open cluster to feature the “Halloween Cat” asterism. A subgroup of brighter stars in this cluster appear to delineate a cat with forward facing eyes, arched back, and raised tail.
