      19th century, Europe

      Transit instruments like this one, with the telescope suspended to swing vertically, were designed for observing stars as they cross the observer’s meridian, a guide to deriving the exact time. The adjustable sighting tube and crosshairs in the telescope eyepiece allow precise observations.
