Telescopes
Invited to design a mounting for the Isaac Newton (optical) telescope, Wallis produced a design for the whole telescope and the building to put it in, but his design was not taken up. His ideas later fed into a design for a large radio telescope, which was adopted for the
Parkes Telescope in New South Wales, Australia. Completed in 1961, it included a dish with a geodetic structure and a mounting of novel Wallis design, both of which are still in use today. The telescope’s “finest hour” was receiving part of the first TV broadcast from the Moon.
