Large, bright and easily visible to the naked eye, M7 is one of the best open clusters in the southern sky for small telescopes. It is an excellent object for binoculars and in a wide field telescope, the view is magnificent. The most southerly of the Messier objects, M7 is situated in a very rich portion of the Milky Way which adds to the beauty of the view.
The bright cluster to the upper left is M6.
To the right of the cluster, just a little above centre in this image, is a small orange object. This is the distant globular cluster, NGC 6453. This object is a good challenge for an 8" telescope.
