Meade #933 07220 45 Deg Erecting Prism Diagonal for ETX 60 70 80

Meade #933 07220 45 Degree Erecting Prism Diagonal for ETX 60 70 80


Standard 45 degree diagonals will not come to focus with these models, you must use the 933 Meade 45 degree diagonal with the etx60, 70 and 80 to reach focus with a 45 degree diagonal.  The 933 diagonals have an internal lens to allow them to achieve focus with those telescope models.

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
