Telescopes contain internal mirrors that reflect light to the telescope's astronomical observing position. In this position, the telescope's image is upright, but reversed left-to-right. This is of little consequence for astronomical viewing, but for terrestrial observing it is highly desirable to have a correctly oriented image. The #928 Erecting Prism delivers a fully corrected image and provides a convenient 45 observing angle for optimal terrestrial viewing.
