Above is shown the image of a distant quasar (redshift = 0.32), constructed using survey data from Halca and five ground radio-telescopes. Although the image was constructed using only about 1/2 hour of Halca data, the resolution is considerably improved over an image made without the Halca data (shown as green contours). On this image, one milli-arcsecond of angular distance corresponds to approximately six parsecs of actual distance (H = 75 km/s/Mpc).
