Sandqvist 111 & 112 are a complex of dark nebulae in the constellation Vela. These are formed when jets of gas ejected by young stars collide with clouds of nearby gas and dust. These dense dark nebula are embedded in the larger emission nebula ESO 210-6A. It contains a spectacular Herbig Haro outflow called HH 46-7, which is probably the most well known and studied southern Herbig Haro object. The smaller dark nebula Sandqvist 112 also includes the dark nebula TGU H1713, which includes the small yellow reflection nebula Vdb 16.
