Has tasco 15X erecting eyepiece with Sr 4mm end piece... cant focus..the eyepiece end is threaded on inside..only 1 lens is in it at viewing end... is one missing???
Probably -- the 4mm gives too much magnification for you telescope-- difficult to focus or find thing in the sky-- you should also have had an eyepiece somewhere between 17mm and 24mm for lower power viewing.

OR at least something around 12mm-14mm
