    How do I prepare a slide?
    Community Answer
    Put the object you are observing on the slide, and carefully cover it with a coverslip (a small, square, clear plastic cover). Make sure the coarse adjustment knob is rotated all the way down, especially if you are at 40X magnification. Place the slide underneath the eyepiece, with the coverslip side facing up.
