NGC 1233 (also listed as NGC 1235) is a spiral galaxy in the constellation of Perseus. Its velocity with respect to the cosmic microwave background is 4218 ± 14 km/s, which corresponds to a Hubble distance of 202.9 ± 14.2 Mly (62.22 ± 4.36 Mpc). In addition, three non redshift measurements give a distance of 211.35 ± 2.14 Mly (64.800 ± 0.656 Mpc). The galaxy was discovered by French astronomer Édouard Stephan on 10 December 1871. It is also thought to have been observed by Lewis Swift on 21 October 1886, and later listed as NGC 1235.
