Open cluster NGC 1647 in Taurus depicted below is a bright and rich open cluster comprised of over 100 member stars which are well interspersed and detached from the background sky. The cluster is dominated by many mag 8 and mag 9 stars with its brightest star being mag 8.3 (SAO 94100). The cluster spans 40 arc-minutes in diameter, lies 1760 light-years away and has been estimated to be about 145 million years-old. The cluster is best observed using low magnifications (50-100x) during winter when it is directly overhead and can be found to lie just to the northeast of Aldebaran (α-Tau, mag 0.87). NGC 1647 was discovered by Friedrich Wilhelm Herschel (1738-1822) in 1784. Further details at http://www.perseus.gr/Astro-DSO-NGC-1647.htm .
