Samples are interrogated in a 4~K closed-cycle cryostat by a high numerical aperture (NA=0.9, 100$\\times$ magnification) objective that sits within the cryostat, enabling high efficiency collection of emitted photons without image distortions due to the cryostat windows. The locations of single InAs/GaAs quantum dots within a $>50$~$\\mu$m~$\\times$~50~$\\mu$m field of view are determined with $\\approx4.5$~nm uncertainty (one standard deviation) in a 1~s long acquisition.
