Meade #933 45 Degree Erecting Prism Diagonal for ETX 60 70 80 - Plastic VersionPrice includes USA shipping

Standard 45 degree diagonals will not come to focus with these models, you must use the 933 Meade 45 degree diagonal with the ETX-60, 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 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.
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

This is the plastic version that was included in the Meade ETX-80 Observer Series telescopes. We purchased several of these kits directly from Meade and removed these gently used diagonals. They come with both caps and will function the same as the higher priced metal version. Please contact us thru ebay if you have any questions. These are about $20 cheaper than the metal version.
