All astronomical telescopes show images that are upside down --- no up or down in space!

You need an ERECTING prism--

When i read a word on a sign the letters are backwards Why?

Astronomical telescopes usually show an upside down image. There is a good reason for this- erecting the image needs more bits of glass in the light path, which reduces the amount of light and increases aberrations. Even if this is only slight, astronomers prefer to avoid it, and they don't really care which way up the Moon or Jupiter appear.

It is possible to fit an erecting prism or eyepiece to most astronomical telescopes, and some of them come with one. It sounds like you have a partially erecting diagonal fitted- it is flipping the image upright but giving a mirror image side to side.

If you wish to use a telescope for terrestrial objects then you will be better off with a "spotting scope" which is designed to present the image in the orientation you expect.

The image that I see is upside down. How do I fix the problem

All astronomical telescopes have upside down images. This is normal and your scope is NOT broken.

You can buy an "erecting prism" diagonal which will invert the image for terrestrial viewing. Here is a link, but you must measure the hole in the telescope as they come in .965, and 1.25 inch sizes.

Astro-telescopes would need extra glass to invert the image further dimming the images you see in the eyepiece for those very dim night sky objects. Read my Frequently Asked Questions TIP on my profile page. Your question is one of the most asked questions in the Telescope Topic.

Nothing is wrong with the telescope-- buy an erecting prism for day time viewing and use.

Edu science reflector telescope instructions 600x

This is a small refractor telescope-- they pretty much all work the same-- BUT don't expect to get more than 100 power out of the scope. Yes I know the box said 600 power but it's a lie. In my 8 inch telescope I rarely get above 250 power and my scope is many times larger than the one you have--

Now put the eyepiece with the largest number written on it into the telescope-- the LARGER the number the LOWER the magnification. During the day time practice focusing on a distant object --- AND line-up the small finder scope on top with the main telescope tube. Look at the top of a distant light or church steple, or telephone pole. Without moving the telescope adjust the small finder scope by loosening and tightening the screws around the tube holding the finder scope-- put the crosshairs on the same spot as the main telescope.

Now you can use the small finder to locate objects in the sky-- the moon should be your first night time target.

No you do not have anything wrong. When ever light is passed through a lens it is inverted. Binoculars, and land viewing telescopes use a special lens combination or "erecting" prism to flip the image for you. The problem with that is it reduces the amount of light that passes through the telescope. It's not an issue for land viewing because these things tend to be close and bright. For astronomy objects are so faint that you actually get a better view when things are upside down.
