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 1493
NGC 1493 is a barred spiral galaxy in the constellation of Horologium. Its velocity with respect to the cosmic microwave background is 1004 ± 4 km/s, which corresponds to a Hubble distance of 48.3 ± 3.4 Mly (14.81 ± 1.04 Mpc). In addition, six non redshift measurements give a distance of 35.38 ± 1.71 Mly (10.848 ± 0.525 Mpc). The galaxy was discovered by Scottish astronomer James Dunlop on 2 September 1826. The SIMBAD database lists NGC 1493 as a Seyfert II Galaxy, i.e. it has a quasar-like nucleus with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable. According to A.M. Garcia, NGC 1493 is a member of the NGC 1493 galaxy group (also known as LGG 106). This group contains six galaxies, including IC 2000, NGC 1483, NGC 1494, PGC 13979, and PGC 14125. One supernova has been observed in NGC 1493. SN 2024abfo (type II, mag. 16.793) was discovered by ATLAS on 15 November 2024.
