OBJECT DESCRIPTION AND IMAGE SESSION

Almost two degrees west from Messier 7 we find another stellar cloud or star field concentration. It was introduced by Scottish astronomer James Dunlop (1793-1848) in the year 1826. As with others stellar clouds, binoculars and low power telescopes are suitable for exploring this object. (*)

 

NGC 6415 is frequently seen as non existent object. John Herschel with his 18 inches telescope described as "...A great nebulous projection of the Milky Way."

 

The picture is centering NGC 6715 coordinates. Presumably astronomers catalogued a Milky Way star field. Panning the region with low powers is quite evident that the star field become more dense at the object location.
