Product Description
#932 45 Erecting Prism: If the ETX-90EC is to be used for extensive terrestrial applications, the #932 45 Erecting Prism is a useful accessory. Images through the 90 eyepiece-holder appear right-side-up, but reversed left-for-right. The #932 Prism threads on to the telescope's photo port and presents a correctly oriented image as well as a convenient 45 observing angle. An eyepiece of any focal length (magnifying power) may be inserted into the #932 Prism. Note that the flip-mirror control must be in the "down" position for use with the #932 Prism.

 Meade - 45 degree erecting Prism September 10, 2008
Jonathan L (UK and USA)
Ok product - erects nicely but you do lose a bit of quality - Great for viewing land objects through telescope (daughter loved it as she could spy on people nicely) - easier to move telescope but loss of quality too great for astonomy purposes. So think on use before you buy
Great for terrestrial, ok for astronomy May 30, 2001

This 45 degree erecting prism is great for birding or terrestrial viewing but is not suitable for star gazing (imagine if the star is right above your head). For star gazing the prism does not reflect as much light as desired so you won't be able to see dim distant objects easily, for that I recommend star diagonal with everbrite mirror ( from televue), it will cost more but a good investment for anyone who is serious about star gazing.
Useful- but not for astronomy June 16, 2000

This is a generic Pacific-rim made prism imported by Meade, and not terribly different from similar items sold by Celestron, Orion and other popular companies catering to amateur astronomers. It's a useful accessory for nature viewing, but don't try to use it for star gazing. Because of how they're constructed, with multiple reflecting surfaces, erecting diagonals lose a lot of light, something you can't afford when looking at distant, dim images. Worse, they produce ghost images- for every star or planet, you'll see a dim twin nearby. Save it for daylight use, and you'll have no problem.
 Great product December 11, 1999

This prism is needed if you intend to use your telescope for terrestrial viewing and photograpy. If you do not use it, your image will be inverted.
