Meade Model 928 Image Erecting Prism for Meade refracting telescopes#07217. 1.25" barrel. Produces a correctly oriented image and convenient 45° observing angle for terrestrial observations.
Meade refracting telescope models (like all refractors) normally produce an image that is reversed or "inverted" due to the inherent nature of the lenses used in their optical configuration. This left to right mirror reversal of the image poses no problem for astronomy, however in 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 Meade 928 Erecting Prism results in an image which is both right side up and corrected left to right. It also provides a comfortable 45° observing angle which is more convenient for daytime use.
For all Meade refractors with 1.25" focusers including 70AZ, DS-2080 and DS-2090, and LXD75 AR5 and AR-6. May also be used with LX90, LX200 or other Schmidt-Cassegrain or Advanced Coma Free models with a 1.25" eyepiece holder. Note: not compatible with ETX models.
