Question about Optics
SOURCE: upside down images
ALL telescopes will show the image upside-down. You learn to adjust for this. IF you must, they do make a lens called an "erecting lens" that would flip the image back right-side up.

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.

SOURCE: everything is upside down
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.

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.

No, all astronomical telescopes show upside down images. You can buy what is called an "erecting prism" (just Google it) to use for terrestrial viewing.
