OBJECT DESCRIPTION AND IMAGE SESSION

NGC 6480 is a star cloud located in the center plane of our Milky Way, as such it is a region with abundant star background surrounded by two Dark Nebulas: LDN 1795 from de center of the image to the left and LDN 1788 at the bottom right (see annotated image below). Dark nebulae or absorption nebulae are clouds of gas and dust in space dense enough to obscure and block light from background stars.

John Hershel made two annotations and sketched this object form  South Africa. The first one: "An extraordinary B nebulous portion of the milky way, on a black ground v L; an angle taken where there is a * 12m. The second one reads: "The milky way here is so sharply terminated, that the southern half of the field has few stars, while the northern is so full as to be almost nebulous."
