A complex multiple system with an unusually large number of component stars. At the heart of the system is a binary circled by a third star in a relatively close orbit, and beyond this grouping there are at least three further companions following orbits progressively more distant from the central triplet.
Visible in the far east (left) of this image is the dark shape of the Horsehead Nebula, while the bright light of Alnitak in Orion's Belt can be seen shining on the northern edge of the frame. Imagery provided by Aladin sky atlas
