OBJECT DESCRIPTION AND IMAGE SESSION

These three tights Globular Cluster do not belong to our Milky Way but to galaxy neighbour the Large Magellanic Cloud in Dorado. There are very compact and also fits into a very small FOV. It is very unlikely to find a tight quartet like this in our galaxy.

NGC 2164 was discovered by James Dunlop from Paramatta, New South Wales and included as Nº 194 in his catalogue of 1827 using an 9 inches f12 telescope.
