Hi Ryan
What sort of scope is it? Secondly, I am gusesing what you have is a 20mm and a 10mm eyepiece. The magnification provided by your eyepiece is worked out by dividing the eyepeice focal length by the focal length of the scope.
So if you have one of these
http://shop.australiangeographic.com...telescope.html then the 10mm will give 650/10 = 65X and the 20mm one will produce 650/20 - 32.5x
You can get more "powerful" eyepieces but their effectiveness is limited by the scope itself, in a small scope the high power eyepieces are not as effective.
If you are not sure about the scope, perhaps post a picture of it.
Cheers
Malcolm
