Object of the Week: Five-Draw Telescope, unknown maker, Italy, 1700-1750. 2018.8.5. 

The introduction of the telescope in 1608 led to the production of many Galilean telescopes with a single-lens eyepiece, low magnification, and a narrow field of view. The development of the compound eyepiece in 1645 made it possible to use the telescope as a more effective device for astronomical and terrestrial observation. This example could be used for both types of observation: at 44 cm in length, it’s portable, and it provides magnification and a field of view convenient for observing both realms.
