6. How to Focus using Low Power
You must look to the side whenever the stage and lens are moving toward each other.
You may look into the eyepiece and slowly turn the coarse adjustment knob moving the objective lens away from the slide
Move the specimen to the exact middle of the field of view.

7. How to Focus using High Power
Do not move the coarse adjustment knob when you switch to high power.
Parfocal = Once you have it focused under low power, it will be almost perfectly focused for the other lenses unless you incorrectly move it.
Turn the objective lens slowly to high power. It may look like the lens will hit the slide, but if you focused the low power objective properly, it will not hit.
Use only the fine adjustment knob under high power to bring the image into focus.

Use the tweezers to position the specimen in the center of the drop.
Holding the cover slip at a 45 degree angle, lower it slowly over the drop of water.
