IC 4665 is a bright and coarse open cluster easily visible in the smallest binoculars in the constellation Ophiuchus. Roughly three degrees to the east we can find "Barnards Runaway Star". This 9.5 magnitude bright star has the largest known proper motion of all stars. It runs 10" north each year. Barnards star is with a distance of about 6 ly the second closest star (just behind the alpha Centauri star system).
