Meade Model 933 Image Erecting Prism for ETX-60, ETX-70 and ETX-80 Models. Produces a correctly oriented image and convenient 45° observing angle for terrestrial observations. A great item for a home with a view or nature watching.
All ETX-60, ETX-70 and ETX-80 models all feature an internal flip mirror to reflect light to the telescope’s convnient 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. Threads securely onto the rear photo port of the telescope. For all ETX-60. ETX-70 and ETX-80 models.
Note: not compatible with ETX-90 or ETX-125, see item #07210 Meade 932 Erecting Prism for these models.
Product carries full one year Meade factory limited warranty (within US/Canada only).
