M4 Globular Cluster April 6, 2012

Just one degree west of the bright star Antares (2 moon diameters), M4 is one of the easy-to-find globular clusters. It is 100 light-years in diameter and only 7000 light-years away (rather close in terms of globular cluster standards). Sky-Watcher 100 ED 4 in f/9 refractor, Kenko NES mount, Canon 450D DSLR, 60 secexp, IS0 1600. April 6, 2012, Camarines Norte, Philippines. Photo Credit: Anthony Urbano
