Orion troubleshooting why is image 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.

It is normal for astro telescopes to show an inverted image. It may seem odd but this is the case. It does not matter when viewing stars, but occasionally it is a problem eg for lunar viewing.

Therefore, and for land "terrestrial" viewing, you can fit in an "erecting" or "correct-image" prism

There are many brands, some more expensive, for photography

First WHY would you use a erecting DIAGONAL in a reflector style telescope. Upside down images are completely normal for an astronomical telescope. You only need this diagonal for terrestrial viewing NOT for star gazing. ALL astronomical telescopes show upside down and or inverted images- it's completely normal.

If you cannot come to focus with the erecting diagonal, it's probably because the diagonal moves the eyepiece too far OUT away from the point where the scope comes to focus. Again-- you do not use those for night time sky viewing. Just stick the eyepiece directly into the focuser.

All astronomical telescopes show upside down images. For terrestrial viewing you can buy an erecting diagonal--

All astronomical telescopes show upside down images. It's normal.

However, you can buy and erecting diagonal like the one below for terrestrial viewing.

All astronomical telescopes show upside down images. It's normal, no up or down in space.

You will not find an instruction manual. What you need to do is to learn a little Astronomy by buying these two books.

Nightwatch

Both available on amazon.com.

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

You can buy one of these to ERECT the image-- make sure you get the correct barrel size usually 1.25 inch although some of those TASCO scopes are .965 inch. Measure the hole--

Yes all astronomical telescopes are upside down! No up or down in space!

You can buy an erecting diagonal for about $45 from Orion Telescopes to use for terrestrial viewing.

Not upside down---

The eyepiece and focuser is on the FRONT of the telescope. Light enters the tube-- hits the mirror on the bottom-- and bounces back up to the small secondary mirror which reflects it out to the eyepiece.

It's called a Newtonian design--
