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 6384


NGC 6384 is an intermediate barred spiral galaxy located about 77 million light-years away in the northern part of the constellation Ophiuchus. It was discovered on 10 June 1863 by German-British astronomer Albert Marth. NGC 6384 has a morphological classification of SAB(r)bc, indicating that it is a weakly barred galaxy (SAB) with an inner ring structure (r) orbiting the bar, and moderate to loosely wound spiral arms (bc). The galaxy is inclined by an angle of 47° to the line of sight, along a position angle of 40°. The estimated mass of the stars in this galaxy is 105 billion times the mass of the Sun. At one time NGC 6384 was considered a normal galaxy with no activity in the nucleus. However, it is now classified as a transition object (T2), which is thought to be a LINER-type galaxy whose emission-line spectra is contaminated by H II regions in the nucleus.
