The John Benjamin Dancer Antique Telescope
John Benjamin Dancer (1812-1887) made telescopes, microscopes, and other instruments at his shops in England. He was the first person in England to image the Moon through a telescope. The McCarthy Observatory received this donated telescope in 2011; it was mostly intact but needed some serious restoration. That work was done by master craftsman Richard Parker in Connecticut. This telescope was made sometime between 1845 and 1870. It has a 4.25 inch objective, and a 62 inch focal length, giving a focal ratio of about 15 (~f/15).
