1 янв 1718 г. - [1718] John Hadley improves the precision of the reflecting telescope.

Описание:

The reflecting telescope reflected light, instead of warping it. This allowed for more accurate conclusions to be made on positions and colors of astronomical objects; and with John Hadley's improvements, the reflecting telescope became the most trusted and only commercially used telescope in the world.
