 | M4, nestled near the ruby blaze of Antares, is one of the great globulars in the sky, but to see it with the naked eye from North America requires perfect conditions. A 8 -10 inch telescope will show how beautiful this cluster is with it's back drop of galactic stars. This cluster is faint, but is definitely there. It is large, about the size of M13. The shape is difficult to discern because of its faintness. It does appear to be not quite round. |
