M7 Ptolemy’s Cluster April 2012

M7, also called the Ptolemy’s Cluster, is an open cluster in Scorpius, with its stars spread in such a large area (1 degree), and thus, best viewed with a pair of binoculars. With a small telescope and on a dark clear night, fainter stars in the cluster may be observed. Sky-Watcher 100 ED 4 in f/9 refractor, Kenko NES mount, Canon 450D DSLR, 60 sec exp, IS0 1600.
