NGC6590 is an unusual emission and reflection nebula located in the constellation Sagittarius. It is a very dim, revealing itself only in deep CCD or photographic exposures like this one shot by David Malin with the 4 meter AAT telescope at the Anglo-Australian Observatory. The complex NGC6589-90 is quite similar to NGC6559 located just 4.5 degrees away. NGC6559 and NGC 6590 are seldom imaged by amateurs, perhaps because they are surrounded by numerous and much brighter deep sky objects embedded in the Summer Milky Way.
