Use the Meade 932 Erecting Prism for ETX-90 & 125AT to correct images to your satisfaction. With ETX-90AT and ETX-125AT Astro Telescopes, images are reversed left to right, which isn’t desirable for terrestrial viewing. You want telescope accessories like the Meade #932 erecting prism, which delivers a fully corrected image with a 45-degree observing angle. This hardly matters for astronomical viewing, but for terrestrial observing it is important to have a correctly oriented image. ETX-90AT and ETX-125AT Astro Telescopes include an internal optical-flat mirror to reflect light to the telescope’s 90 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. With the telescope accessory, the #932 Erecting Prism, you get a fully corrected image and provides a convenient 45 observing angle for optimal terrestrial viewing. Shop for the Meade 932 Erecting Prism for ETX-90 & 125AT, and obtain the best angle for terrestrial viewing.Price: $ 49.95 Read More and Buy it here!
