How do I get my Telescope to work?
I am very new to telescopes. I just bought a telescope, and everything that I look at on land is upsidedown. When I want to look at somehing here on earth, How do I get the picture rightside up?

Stand on your head or turn telescope over. Failing that rotate the knob on the side. If none of those things work then I suspect operator error

Study lenses. You’re useing the wrong size magnifying glass inside for the distance you want to see.
Find another lens to put in for closer images, or look at things farther away.
You would have to add an extra lens. Basically anytime light passes through a lens the image is inverted (flipped). The light from the “top” of the object passes through the lens and appears on the “bottom” of the image on the opposite side of the lens. In a telescope this image usually is refined through another lens, which again inverts the image. In your case the image is passing through an odd number of lenses, causing the final image to appear inverted. If you get a new eyepiece that will give your telescope an even number of lenses you should see the image right side up.
What you have is an astronomical telescope. They give an inverted image because that’s the way it comes out, and for astronomy there’s no need to re-invert it. If your telescope is a refractor or cassegrainian reflector, you can buy a “correct image” or terrestrial diagonal for it. If it’s a Newtonian, you need an erecting eyepiece.
Telescope optics naturally turn the image upside down. Telescopes for astronomy don’t bother to correct this because there is no point – there is no up or down in space.
You bought an astronomical telescope – use it as such.
In fact, I will modify that. Sell it. You need a good bit of skill and knowhow to use an astronomical telescope effectively. You obviously have not the vaguest idea. Give it up.
Optics – microscopes and telescopes all invert the image because if they didnt, it would
mean that another lens had to be added, increasing money cost. A lens is convex on both
sides. That means the middle is thicker than the edges. A microscope or telescope has two
lenses (basically).
The objective lens (usually larger and closer to the specimen or object) which allows the
image of the object to be reduced to a smaller workable image inside the scope.
This image is inverted inside the scope. It is also too small to see with the eye, so you
need another lens, the eyepiece. The eyepiece focus’s your eye on the image and magnifies
it so you can see it. Every lens has a focal length, the point at which the image is formed
away from the surface of the lens.
Turning the scope around will have no avail,
If the scope has a star diagonal, you can rotate that to see things up right.
