Astronomical telescopes do not include the extra lens needed to show things right side up. It isn't considered important which way is up when looking at the sky and leaving out the extra lens reduces cost and improves image quality. Terrestrial telescopes, like spotting scopes and binoculars, use an erecting prism. You can also get erecting eyepieces for astronomical telescopes, but almost nobody does that. With a Newtonian reflector looking at things on the ground you can see the image right side up by standing with your back toward the object the telescope is pointing at when you look through the eyepiece....

We own three. We have a big sky:D

We have the ones that: used as a land telescope turns everything upside down but mount it everything in the sky is the right way up. the erecting prism.

I might have known you'd have an erecting prism....
