But since time slows down aboard the starship, according to Einstein's special theory of relativity, the crew could reach the Pleiades star-cluster (M45), which is 400 light-years away, in as little as eleven years, by the clocks aboard the starship. After 25 shipboard years, such a ship could even reach the Great Andromeda Galaxy - although over 2 million years would have passed on the earth.

NGC 1664 (Open cluster) Right ascension: 4h 52m Declination: 43° 42' Constellation: Auriga Date/time: 2014.03.08 20:45 UT Equipment: 12" f/5 Newtonian FoV: 36' Magnification and filter(s): 100x Seeing: 7/10 Transparency: 2/5 SQM: 17.95 m/as2 Temperature: 6°C Humidity: moderate Wind: gusts Sight: 4 - lots of details, very interesting, unique look Difficulty: 3 - moderately visible, dark adaptation needed, averted vision might add to details Position: 1 - very easy, many bright stars nearby Location: Nádasdladány, Hungary Observer: Ferenc Lovró Description: Faint, large open cluster with member stars of very similar brightness. Sparsely populated, yet it features many spectacular stellar paths. A really nice object, should make a great target on a better evening. In the Eastern corner of the FoV I can see a really nice, perfectly square pattern of stars. The Half Moon is near the Auriga constellation, and sometimes stormy wind gusts make observation harder.
