From what distance is our own Sun visible?

From the distance of Voyager 1(farthest man-made object) the Sun is still at a magnitude -16.4 which is brighter then the Moon and from the Alpha Centauri star system the nearest to our own the Sun would appear around as bright as Capella in our sky(magnitude .71) at Aldebaran 65 light years away the Sun would appear as a 6.4 magnitude star only just within capability of human vision(magnitude 6.5).
