We propose to obtain high spatial resolution images of fields containing the {currently} unresolved images of the source plus lens for a sample of recently detected microlensing events in the Large Magellanic Cloud and the bulge of the Milky Way. The deep images of the sources will provide first epoch images for comparison with later images to resolve the proper motion of the lensing object, if it is luminous. If the lens is not resolved on later images, this is strong evidence that the lenses are not members of the luminous stellar component of disk or near halo. These measurements cut to the heart of the dark matter controversy in the halo of the Milky Way. We also propose to determine the stellar luminosity function in these crowded fields to three magnitudes fainter than surveyed by our ground based search in order to determine the effect of blending and confusion on our microlens detection efficiency.
