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 7124
NGC 7124 is a large spiral galaxy in the constellation of Indus. Its velocity with respect to the cosmic microwave background is 4988 ± 15 km/s, which corresponds to a Hubble distance of 240.0 ± 16.8 Mly (73.57 ± 5.16 Mpc). However, nine non-redshift measurements give a much closer distance of 191.56 ± 4.26 Mly (58.733 ± 1.306 Mpc). It was discovered by British astronomer John Herschel on 8 July 1834. NGC 7124 is classified as a LINER galaxy, i.e. it has a type of nucleus that is defined by its spectral line emission which has weakly ionized or neutral atoms, while the spectral line emission from strongly ionized atoms is relatively weak. One supernova has been observed in NGC 7124: SN 2023pwl (type Ia, mag 16.7) was discovered by ATLAS on 19 August 2023.
