The central Globular Cluster is NGC 104. Like the Milky Way, the SMC has a halo of Globular Clusters. There are 4 additional small Globular clusters which are part of the Small Magellanic Cloud and numerous galactic open star clusters. The Small Magellanic Cloud is just visible in bottom left. No galaxies in this image, its all stars. Dimmest stars are about 18th mag.
