NGC 6681 is a collapsed core globular cluster with a power-law visible surface brightness profile. Far ultraviolet images obtained with WFPC-2 show a sparsely populated central region fully resolved into stars. A far ultraviolet to visible color magnitude diagram shows a well-defined horizontal branch with no evidence for evolved descendents. The blue horizontal branch stars are less centrally concentrated than the visible light. The center possibly harbors two blue stragglers.
