All astronomical telescopes show upside down images. You would need to add an additional "erecting prism" to turn them right side up. This just puts more glass between you and the dim sky image. You can buy an "erecting prism" from many on line retailers.

Here is one:

Need to find replacement lenses got at a pawn shop as a freebie with purchase of another scope


Eyepieces can be bought at many on line retailers. Here is one, your scope probably uses the 1.25 inch size-- measure the hole in the focuser.

A friend of mine just purchased a used Polaris 60EQ-D telescope and asked if it can be used for terrestrial viewing. Are there any types of lens adapters to flip the view to right side up?


Yes they are called "erecting diagonal" like this one:

NO it is NOT missing a lens-- all astronomical telescopes show upside down images.

You can buy an "erecting prism" diagonal for terrestrial viewing, but you do not need it to view the night sky.

Here is an example of the erecting prism:

Bought a Geovision Precision Optical Omega Reflector telescope with a manual from a garage sale, please help locate the instruction manual, or tell me how to get the view right side up.


The view through an astronomical telescope is always upside down. When your looking at stars and planets, it makes no difference. If you want terrestrial view, get spotting scope - that's not what reflectors are for. If you still insiste on view right side up, you'll have to buy and inverting eyepiece or adapter and probably spend more than you paid for the scope.

Viewing right side up


ALL astronomical telescopes are upside down--- no up or down in space!

You can buy an "erecting" diagonal which will invert the image for terrestrial viewing--

Want to see images right side up


You do not need an erecting prism to view objects at night. These are used if you wish to view terrestrial objects since it turns them right side up.

If you have a reflecting telescope (it uses mirrors) it's normal to not use an erecting prism or as they are also known as star diagonals. Objects will appear inverted and that's normal. A refracting telescope (no mirrors, just lenses) will also invert the image but it is quite often used with a star diagonal to make it easier to view. There are many other types of telescopes that use a combination of mirrors and lenses.

I hope this helps.

Just bought a cheap, used Tasco telescope. Images


I'm not sure what type of telescope this is (refractor, reflector, etc.) but it's normal for most telescopes to have inverted images. There is no up or down in space so it doesn't really matter when you view an astronomical object. You just want to keep that in mind if you use a moon map so that you can get the correct orientation. However, you can get moon maps with inverted images.

If you wish to view land or terrestrial objects you can purchase an image erecting prism to turn everything right side up. Depending on the telescope it may reverse the images from left to right when it does this.

I hope this helps.
