  We discuss lensing properties of the nearby cluster Abell 2152. Recent work
shows that Abell 2152 is actually the projection of two different clusters, one
of which is a Hercules supercluster member at z=0.043, while the other is more
than 3 times as distant. The cluster centers have a projected separation of
only 2.4 arcmin, and our data indicate that the foreground cluster lenses
members of the background one. We have an ongoing program to measure the
magnification of the fundamental plane in the background cluster. The
magnification of this standard rod will provide an estimate of the foreground
cluster mass free from the uncertainty of the mass-sheet degeneracy which
affects mass estimates based on weak shear.
