Your telescope is a reflector. Light enters the tube, and strikes the primary mirror in the back, which is parabolic like a satellite dish. The mirror directs all the light it could gather to the secondary mirror upfront. If you could see the light being directed to the secondary mirror, it would appear as a cone with the tip chopped off due to it striking the secondary mirror.
The primary mirror, being parabolic, flips the image when viewed from past a certain distance away, because of the way it directs the light. If you ever come across those magnifying beauty mirrors, it's the same deal. You'll find that at a certain distance, the reflection of your finger appears on the opposite side that your finger is actually on. You can even find a point where your finger and it's reflection is pointing right at eachother and you can't tell the difference between which is the real object and which is the reflected image!
Anyway some people are bothered by the fact that the image is "upside down" in reflectors and there is a way to correct for it, as other people have mentioned. But keep in mind that in space, there is no up or down, so there's no such thing as upside down. You really get used to it quickly when aiming the telescope on things and recentering objects.

Images from telescopes usually are up-side down or mirror-imaged. If you have a refractor type telescope, all you need is an "erect image diagonal" to replace the "diagonal" that you're using now.

It's a refractor type telescope. You'll need a special refractory lens to invert the image to what you're use to seeing. Most hobby shops and maybe camera shops can help you.

Beg pardon. Its the reflector telescope which inverts the image. You will need a corrective lens for it. See this link:

Thats just the affect that the lenses have on the image. Not familiar with the scope you have but I assume that its a refractor type. If i am not mistaken you can buy am image wrighting lense which will flip the image 180 degrees for you.

did you it assembled, or put it together yourself?
