Put the eyepiece with the LARGEST number written on it into the telescope. Go outside during the day time and practice focusing on a distant object.
This is your LOWEST magnification. Then try other higher power eyepieces. While you are out there focused on a distant object. Line up the small finder scope on that object without moving the telescope. Use the small thumb screws on the finder scope to put the "X" crosshairs on the same object as you see in the eyepiece.
