Turn the diagonal, and the image rotates. Using the scope for star gazing it does not matter. Normally an astronomical telescope shows an upside down image--- no up or down in space. The erecting prism is only used for terrestrial viewing as the prisms inside are probably NOT multi-coated.

My telescope is showing upside down


All astro telescopes will normally show an inverted image. If you want to use it during the daytime you can fit an erecting prism between the lens and the focuser, like this

Why are the lens upside down help


It is normal for an astro telescope to show objects upside down, as when viewing astro objects this makes little difference. If you want to view terrestrial things, such as your neighbor's bedroom window, you can fit an erect image diagonal, such as

I look through my 6mm vivitar lens and the view is almost upside down?


All astronomical telescopes show upside down and or inverted images-- it's completely normal. To use this for terrestrial viewing (klijke a spotting scope) you will need to buy the correct size erecting prism diagonal similar to this one:

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".

All astronomical telescopes show the image upside down. It's tradition and there is a good technical reason for this, but you can get an "erecting prism" to make the image upright. This does not have to come from Edu-Science if your eyepieces are the standard size (1.25 inch outside diameter). If you search Amazon or eBay for "erecting prism" you will find a few available. You probably won't want to pay the prices though.

Without a porro-prism or a erect image diagonal, all telescopes show a reversed image. This is normal. There is no up/down in space. If you want to use the scope for terrestrial viewing, see first sentence. Do not use a erect image accessory for astronomy since it reduces the contrast.

Upside down images


ALL astronomical telescopes show upside down images it is normal. Put the eyepiece with the LARGEST number written on it into the diagonal. Do NOT use the 2x barlow it is too much magnification for that small aperture telescope.
