Preliminary results are presented from Rayleigh beacon closed loop images of the large asteroids Ceres, Pallas, and Vesta obtained with 1.5 m telescopes of the USAF Phillips Laboratory's Starfire Optical Range. Measurements of the apparent diameters of two post-processed images of Ceres lead to excellent true diameter, and of two images of Pallas to good true values. Measurements of images of Vesta on two occasions lead to the full triaxial ellipsoid solution and rotational pole direction, all in excellent agreement with previous speckle interferometric results. A preliminary iterative blind deconvolution image of Vesta obtained from three 20 sec integrations is presented.
