Does a refracting telescope with converging lenses make an upright image?

So I have a final project to make a refracting telescope, I made the telescope already, but the kit I used did not determine what kind of lenses they were, converging or diverging. So if I have a refracting telescope with 2 converging lenses what kind of image would it make? Inverted or upright? Please please please help! 10 points to the best answerer, plus my eternal thanks! -pce

A telescope made with two converging lenses would have an inverted image. Can’t you see that?
The telescope kit you bought is most likely a Keplerian type. If all that you have are two lenses that are both positive (converging) then you would have an inverted image. Unless the kit comes with a Porro prism or an Abbe roof prism then the image will actually be upright.
