Highly sensitive and precise X-ray imaging from Chandra, combined with thesuperb spatial resolution of HST optical images, dramatically enhances ourempirical understanding of compact binaries such as cataclysmic variables andlow mass X-ray binaries, their progeny, and other stellar X-ray sourcepopulations deep into the cores of globular clusters. Our Chandra X-ray imagesof the globular cluster NGC 362 reveal 100 X-ray sources, the bulk of which arelikely cluster members. Using HST color-magnitude and color-color diagrams, wequantitatively consider the optical content of the NGC 362 Chandra X-ray errorcircles, especially to assess and identify the compact binary population inthis condensed-core globular cluster. Despite residual significant crowding inboth X-rays and optical, we identify an excess population of H{\alpha}-emittingobjects that is statistically associated with the Chandra X-ray sources. TheX-ray and optical characteristics suggest that these are mainly cataclysmicvariables, but we also identify a candidate quiescent low mass X-ray binary. Apotentially interesting and largely unanticipated use of observations such asthese may be to help constrain the macroscopic dynamic state of globularclusters.
