Hi
Telescope eyepieces are interchangeable between brands of telescopes and eyepieces, but only up to a point.
First, check the diameter of the opening in the focuser. It will be either .965" or 1.25"
If the opening in the focuser is .965" (just under an inch), eyepiece selection and accessory selection will be very limited, since this size is now obsolete.
If the opening in the focuser is 1.25", there are many choices for eyepieces and accessories You can see all our telescope eyepieces on our website under telescope accessories.
To determine magnification with any telescope and eyepiece, divide the focal length of your telescope (usually marked in mm on your telescope) by the focal length of the eyepiece. For small telescopes, it is not advisable to excceed 120x.
Please note that repairing inexpensive telescopes or replacing accessories on them is seldom cost effective. For what it costs to replace a set of just two or three eyepieces - the usual number used - you can buy a brand new telescope complete with all parts including mount, tripod, eyepieces, finder scope, instruction manual and so on. You can see all our telescopes at http://www.opticsplanet.net/telescopes.html
