The Meade #933 Image Erecting Prism for ETX60, ETX70 and ETX80 telescopes produces a correctly oriented image and convenient 45? observing angle for terrestrial observations. It is a great item for a home with a view or nature watching.
All ETX60, ETX70 and ETX80 models feature an internal flip mirror to reflect light to the telescope?s convenient 90? astronomical observing position. In this position the telescope?s image is upright, but mirror-reversed left to right. While this is normal and poses no problem for astronomy, for terrestrial observing a corrected image is highly desirable, which is where this useful accessory comes in.
For observing wildlife, a home with a view, or other Earthly applications, the #933 45? Erecting Prism results in an image both right side up and corrected left to right. It also provides a comfortable 45? observing angle which is more convenient for daytime work. The prism threads securely onto the rear photo port of the telescope.
- Compatible with ETX60, ETX70 and ETX80 telescope models.
- Not compatible with ETX90 or ETX125, see Meade #932 Erecting Prism for those models.
