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.

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.

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.

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

Not only is this a high quality piece of equipment that mounts easily and makes my Meade ETX into a dual purpose viewer, but better yet was the price. Best price I found online period and free shipping. Look, the resellers don’t make the items, they just make the profit so for me the lowest price wins every time. I got what I paid for and more. Thanks Amazon for a great deal and free shipping.
