Eyepiece by Johann Alexander Herschel zoom

Eyepiece

This eyepiece has a focal length of 2.49 mm. It has a mount with a small thread and a milled edge. William Herschel's eyepieces, made for him by his younger brother Alexander are outstanding because of their magnifying power which was exceptionally high for the time.

In his 'Account of a Comet', read to the Royal Society in April 1781 (the comet in question was later confirmed to be Uranus) he referred to having 'ready at hand the several magnifiers of 227, 932, 1536, 2010'.
