When I look through my telescope it's upside down
The image in astronomical telescopes are naturally upside down. This can be corrected using an inverting eyepiece . The reason this is the case, is that normally when viewing astronomical objects it doesn't matter if the image is upside down, so to minimise the loss of light that is the more important issue, unnecessary optical surfaces are eliminated. Terrestrial telescopes do naturally have inverting eyepieces as people expect to see objects the right way up.
Getting and inverting eyepiece will be cheaper the changing telescopes! :) Your eyes see everything upside down too, but your brain turns the image the right way up. The image in cameras is also upside down at the image plane, but the electronics turn it the right way up for you.

If things are upside down in your telescope, you probably have a reflector telescope.it has curved mirror in the sealed end.take off the cover near the finder and point in the general direction of what you want to see.Make adjustments with the stuff on the mount.If you are viewing terrestrial objects, you will need an inverting lens to correct the image.It is called a Barlow lens and is much longer than the other lenses that come with the telescope.Good Luck
SOURCE: upside down images on my telescope. Bought used -no manuel. What to do?
In a refractor images are upside down as with most telescopes. You need an image erector to create a normal correct R and L and Up and Down image. It is a lens which goes in front of the eyepiece to give a correct image.

Astronomical telescopes produce an upside-down and reversed image (image is rotated 180 degrees from an upright position) since this doesn't matter when you are looking at things in the night sky. Accessories are available for rotating the image to an upright position, but most of those accessories do not work well with Newtonian style reflector telescopes such as the 114EQ reflector.

Yes, all astronomical telescopes show images upside down. There is no up or down in space.
SOURCE: Just came into a used tasco 302048 . Everything is upside down!!!
the scope is made for both terrestrial viewing and astronomical. In order to see terrestrially upright, you need an inverting STAR DIAGONAL. The eyepiece will do nothing for inverting the image. you might have 2 diagonals in the kit that came wih the scope. the diagonal is the part that fits into the scope. then you place the eyepiece in the diagonal. if you have 2 diagonals , one is a 90 degree angle,(astronomical) and one is a 45 degree angle, (terrestrial). the eyepieces change the magnification of the image. the bigger the number (9mm, 20mm, 26mm,) the smaller the image. the smaller the number , the bigger the image gets. the number is inverse of the image. Hope this helps.
