SOURCE: everything in telescope is backwards

These are normal for an astronomical telescope. You can get erector prisms to fix it for terrestrial use - but astronomers just live with it.

Having been given a Celestron LT 76AZ for Christmas, the viewer seems to be in the wrong place, ie horizontal, and the image seen is upside down - can I rectify this?

This telescope works by a mirror. The image is upside down, sorry.
However you might want to get a Telescope USB camera, then you can see the image on your PC the right way up.

Images are upside down with the eyepiece installed

Astronomical telescopes are made this way. (There are RACI-right angle correct image) finders on the market. It just takes some getting used to.

The image is upside down

Yes, all astronomical telescopes show upside down images--- no up or down in outer space-- and you would need more lenses in the light path to erect the image.

How to install the eyepiece

Is your scope like the picture? If it is it is a REFLECTOR style with a mirror on the bottom.

Put the eyepiece into the focuser-- this is the UP end of the telescope. The large mirror is on the DOWN end. I have seen many beginners mount these upside down with the open end pointing at the ground!

Can you tell me where i can buy an image erector, thanks

Yes, but it will probably cost almost as much as you paid for the scope:

here is one:

All astronomical telescopes show upside down images, it's normal. The erecting diagonal is only used for terrestrial day time viewing, of land objects.

Everything is upside down on side eye piece. When viewing through the scope that's on the side of the telescope itself, everything is upside down. No matter which way it is turned, the same problem exists.

All astronomical telescopes show upside down images. It's completely normal. Nothing is wrong with the scope. For terrestril viewing you can buy an "erecting prism diagonal" which will turn the images right side up.

Image upside down

Hi, this is a common "problem" for astronomical telescopes. Same with my Meade 3" refractor and spotter. It is actually a design 'feature' not broken.

The issue is that most astronomical telescopes naturally show images upside down, or some combination of upside down and left-right.
(Astronomers usually don't care, because space has no up or down.)
It is just the way optics work when lenses or mirrors bounce and bend light. (And since the professional astronomer wants the most light and most direct image, they usually don't want extra devices just to make it right-side up.)

Reason that binoculars don't do that , is they employ special internal prisms to get the image back right-side up.

Easiest solution for astronomical telescope is to buy what is called a "star-diagonal" or "image-erector prism". These will usually make the image look normal for us earth-based folks.

I do not know what exact type your Meade 227 telescope is, but the spotter scope is most likely a simple refractor. So it MAY be possible to install a star diagonal onto it. Or might not. Depends on the exact spotter scope design.
Another option may be able to buy a replacement spotter scope that is designed for correcting image orientation.
