There are few objects of particular note in Lupus, the Wolf constellation, but one of them is this very opaque dark nebula, which lies in the foreground and blocks out the light from thousands of stars beyond. This nebula belongs to the group of 42 dark dust clouds of high visual opacity which are referred to by the initials “SL” in some atlases. Finding the correct catalogue names of this rarely imaged objects is quite a challenge and what I mention here may even be incorrect !!
