From Wikipedia

NGC 4650 is a large barred spiral galaxy in the constellation of Centaurus. Its velocity with respect to the cosmic microwave background is 3,239±42 km/s, which corresponds to a Hubble distance of 155.8 ± 11.2 Mly (47.77 ± 3.44 Mpc). Additionally, one non-redshift measurement gives a closer distance of 151.34 Mly (46.400 Mpc). It was discovered by British astronomer John Herschel on 26 June 1834. NGC 4650 is 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.
