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 closer 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.
