NGC 3905

NGC3905 is a barred spiral galaxy in the constellation of Crater. Its velocity with respect to the cosmic microwave background is , which corresponds to a Hubble distance of . However, six non-redshift measurements give a closer mean distance of . It was discovered by English astronomer Andrew Ainslie Common in 1880.

NGC3905 is 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.
