Subject: Astronomy
Physical descriptionInk on paper
Notes'The problem of increasing length of telescope had to be addressed if telescopes were to continue to improve. Hooke had a number of approaches. One was to dispense with the tube, to produce the 'aerial telescope' where the observer controlled the objective mount from his station at the eyepiece, usually by means of a line, as with this telescope. The technique is generally associated with Huygens, who described it in 1684. In fact, Hooke described it to the Royal Society in 1678 and his use of it seems to go back to 1669, or 1668, if that special case of the zenith telescope at Gresham is included.' (From Jim Bennett, 'London's Leonardo' 2003, Oxford University Press page 95)
