Undaunted, he built his own telescope in 1926. (Apparently he built it out of a kit from the [[Sears]] catalog.) The results did not satisfy him. So he self-educated in the science of [[optics]], and built two more telescopes. He ground his own lenses and mirrors to build these. He drew the [[Solar System]] (as it was then known) from his observations, and sent his drawings to the [[Lowell Observatory]] in [[Arizona]] on or about 1928. The drawings impressed the directors, who invited him to join its staff. | Undaunted, he built his own telescope in 1926. (Apparently he built it out of a kit from the [[Sears]] catalog.)
