Image size and motion observations have been conducted at 0.8 microns and various IR wavelengths with a 2.3-m telescope, and at 0.6 microns with the Multiple Mirror Telescope (MMT). The latter observations were used to determine the isoplanicity of the atmosphere for image motion, the time development of image position, and the telescope-to-telescope correlation of image motion. At both telescopes, the image size was larger than expected for the image motion, and a finite outer scale of atmospheric turbulence did not appreciable reduce the MMT's image motion. The excess image size is largely caused by excess small scale turbulence, presumably inside the MMI telescope dome.
