Abstract
The binaries-in-clusters program of the Rothney Astrophysical Observatory has targeted eclipsing binaries in galactic star clusters since 1975. The program uses a boot strap method: fundamental star data are obtained from light curve analysis and these data then elucidate the properties of the cluster environment, such as the distance, reddening, and, through isochrone fittings, information about the age and evolution of both binary components and the cluster as a whole. Here we discuss its current status and the increasingly important role of all-cluster direct and spectroscopic imaging.
