👉 A spectaculum, also known as a spectacled or spectacle, is a type of astronomical instrument used to view stars. It consists of a telescope that is equipped with a large mirror and a lens. The eyepiece allows viewers to see the stars through the telescope's aperture, while the objective lens magnifies the image on the screen. Spectacles are commonly used in astronomy for observing celestial bodies such as planets, moons, and asteroids.
