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 3430
NGC 3430 is a barred spiral galaxy in the constellation of Leo Minor. Its velocity with respect to the cosmic microwave background is 1,869 ± 20 km/s, which corresponds to a Hubble distance of 89.9 ± 6.4 Mly (27.57 ± 1.95 Mpc). In addition, 22 non-redshift measurements give a distance of 85.97 ± 3.77 Mly (26.359 ± 1.157 Mpc). It was discovered by German-British astronomer William Herschel on 7 December 1785. NGC 3430 is classified as a well-known example of an SAc spiral galaxy with no central bar structure but has spiral arms found open and clear-defined. Moreover, it is also a Wolf-Rayet galaxy, with star-forming regions and forms a pair with NGC 3424, a nearby starburst galaxy. According to a 1997 study presented by researchers, these galaxies are clearly showing signs of tidal interaction.
