“Terrestrial” views refer to observing objects on Earth, such as landscapes, wildlife, or sporting events, using a telescope. “Celestial” views, on the other hand, involve observing celestial objects in the night sky, such as stars, planets, nebulae, and galaxies. To switch between terrestrial and celestial viewing modes, telescopes may require adjustments to focusing, eyepiece selection, and, in some cases, the orientation of optical components or accessories. Some telescopes come with flip mirrors or erecting prisms for easier transition between viewing modes.
