It is normal for a telescope to invert the image. There is no up or down in space so for astronomical use it does not matter.

The reflector telescope is not generally used for terrestrial viewing. However, image erectors can be purchased and are inserted before the eyepiece. This would make everything right side up.

Why is the view on my Astro-Nova 102 telescope upside down?


All astronomy telescopes show the image upside down. Using a erect prism eyepiece fixes this but is not for astronomy, only terrestrial views because of light loss

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.

You only use this for terrestrial viewing, all astronomical telescopes show upside down images. It's normal.

However, what you need is called an "erecting prism" these are available from several on-line retailers. Here is one for sale:

You have two problems: First the erecting prism probably costs almost as much as you paid for the telescope. Second they usually come ion 1.25 inch size, your telescope may be a .965 inch. Measure the hold where the eyepiece goes and see which size you have.

Sometimes Telescope Warehouse on Ebay has the .965 size.

My 102mm astro-nova telescope shows everthing upside down. am i missing a piece for my telescope?


No, all astronomical telescopes show upside down images. You can buy what is called an "erecting prism" (just Google it) to use for terrestrial viewing.

Remember --- no up or down in space! Read my "TIPS" in my Profile, called ----"Frequently Asked Question".

Received 102mm astro-nova telescope for xmas. How do you use it? Came with no instructions. Not sure which end to point at the object to be viewed. Removing what looks like a lens cap does nothing.


The eyepiece is on the FRONT end of the telescope which is pointed UP.

The mirror is in the bottom.

Remove the lens cap and put the eyepiece with the largest number written on it into the focuser. Go outside during the day time and practice focusing on a distant object. The image will be upside down but this is not a problem. NO up or down in outer space!

I have the astro nova 102mm and everything looks upside down when I look through it


All astronomical telescopes show upside down images. There is no up or down in space. Erecting the image would require more GLASS which would dim the image.

My astro-nova telescope shows things upside down why?


This is an astronomical telescope, and that is a normal condition. Use a mirror diagonal to correct.
