No, they don't have to be Celestron branded eyepieces.

You calculate the magnification (zoom, to use your term) by dividing the focal length of the telescope, by the field stop (the mm number) of the eyepiece.
For your telescope, the focal length is 900mm. A 10mm eyepiece, for example would give you 90x magnification (900/10).
A 25mm eyepiece would give you 36x magnification.
Does all that make sense?
