Eli Shaw (1821-1869) was a self taught mechanic from Barnsley. He had a Thomas Cooke & Sons 3 feet achromatic telescope. I would assume that this would have a lens of around 3 inches but I have no definite proof of that just the length of the telescope to go by. He observed the Sun, Moon and planets.
He made his own reflecting telescope, I do not know the size of this instrument. He also made his own astronomical clock. On his death he left a large scientific library and various scientific instruments.
