Yes that's correct. All astronomical telescopes show upside down images. Nothing is wrong with the scope.

You can buy an "erecting diagonal" for terrestrial viewing.

Here is one:

Why would the images be upside down


All astronomical telescopes show the image upside down. For terrestrial use, you need a erect image prism.

How do I fix the upside down problem on a tasco telescope


All astronomical telescopes have upside down images. Nothing is wrong with the scope.

NO up or down in outer space.

For terrestrial viewing you can buy an "erecting prism" diagonal like this one--

I have a tasco galaxsee 45-114375 and misplaced my manua. l My image is upside down, how can I change that?


All astronomical telescopes have upside down images. It's perfectly normal.

You can buy an "erecting prism" for terrestrial viewing.

Here is one:
http://www.astronomics.com/main/Image_Erecting_Prisms.asp/catalog_name/Astronomics/category_name/EDNECFUVSRWS8KLNTU5E38XSE1/Page/1

The manual will only have assembly instructions. It will not tell you how to use the scope or how to find objects in the night sky. Read my TIPS on my profile page-- a free monthly star chart is available here:

Everything is upside down! why? how do i fix it?


Astronomical telescopes show upside down images. No up or down in space. To invert the image would require more glass and or mirrors.

You can purchase an erecting prism to use in viewing terrestrial targets.

Just came into a used tasco 302048 . Everything is upside down!!!


the scope is made for both terrestrial viewing and astronomical. In order to see terrestrially upright, you need an inverting STAR DIAGONAL. The eyepiece will do nothing for inverting the image. you might have 2 diagonals in the kit that came wih the scope. the diagonal is the part that fits into the scope. then you place the eyepiece in the diagonal. if you have 2 diagonals , one is a 90 degree angle,(astronomical) and one is a 45 degree angle, (terrestrial). the eyepieces change the magnification of the image. the bigger the number (9mm, 20mm, 26mm,) the smaller the image. the smaller the number , the bigger the image gets. the number is inverse of the image. 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.

The image is upside down in my tasco galaxseer. Please help.


This sounds like a name for an astronomical telescope. I do not own/may have not seen one, but anyway here goes.

Terrestial images do/will appear upside down. This is normal. Just to add to the confusion some telescopes LEFT and RIGHT can be reversed.


First a few Q's & A's
===============
Can you use different eyepieces?

If 'yes' then what is the diameter* where it enters the scope drawtube/foucuser? (the most popular size is 1.25inch the other is .965inch).

You can purchase what is called an "image erecting prism". This should solve your problem. These are available as an accessory from on-line astronomical dealers. Sorry, but I do not how much you will pay.

As there are many telescope manufacturers 'out there', prices do vary. I cannot remember whether Tasco have one made under thier name. If it helps Tasco are owned by Celestron.

Good luck and clear skies.
