Toledo Commences Operation Of 102‐cm Coudé Telescope

Just going into use at the University of Toledo, Ohio is a 40‐in. (102‐cm) Coude reflecting telescope especially designed for high‐dispersion spectroscopy. An unusual hollow‐pier support enables it to accommodate the largest spectrograph one can design with available and contemplated gratings. Also unusual are its optics: All of them (primary, secondaries, folding flats, collimators) are made of a new material, CER‐VIT, developed by Owens‐Illinois just in time for the Toledo telescope.
