All ETX telescopes include an internal, flat mirror to reflect light to the telescope's 90-degree astronomical observing position; in this position the telescope's image is right side up, but reversed. For terrestrial observing, the #932 45-degree erecting prism reorients the image to produce a natural view. In addition, it provides convenient, 45-degree observing angle.
If you plan to use your Meade ETX 90/105/125 telescope for terrestial viewing, the #932 erecting prism is a must-have.
