Not unusual; it depends on the number and kind of lenses being used. If you take a single lense (such as one for aging eyes), hold it between you and a window (or other light source), allow it to shine on a sheet of paper, a wall or even your hand, you will find that the image is inverted. Actually, the light entering your eye is an inverted image on the retina and our clever brains turn it 'right side up.'

Everything is upside down


This is normal for an astro telescope. It is not considered important when viewing stars and so forth.
You can buy a terrestrial viewing prism to correct this

Is there any other way you can find out the serial and model name -number of an older meade telescope .Im looking for a replacement part(diagonal mirror ).Im seeing every thing upside down..I was told it I...


No they do not keep track of serial numbers only the main model number like LX200, LX90, ETX, etc etc--

Everything is ALWAYS upside down in an astronomical telescope. It's normal!

No up or down in outer space. Read my tips on my profile page.

They do make an "erecting diagonal" for terrestrial viewing. Just google "erecting diagonal".

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.

Image is upside down


A telescope sees that way. you have to have a corrective lens to right the view. Its a physics thing about how light goes thru a lens and at the lens flips over upside down, you need another neutral lens to flip it right side up again. If you got the entire kit try another lens till you find the corrective lens.

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.
