this is just to illustrate the importance of centering what you're looking at in the middle of the field of view as you go from one power to the next we field of view decreases so you can see here that you can see the full piece of paper with the letter e on it and I'm going to Center that so that it's right in the middle of my field of view and now and you'll note when we go to the next higher power hey I am not seeing the whole piece of paper and he is a little bit off to the side so what I'm going to show you here I'm refocusing to get it into clear view if I do not Center this when I go up to the next higher power okay it almost is off the field of view out of the field of view I can barely see it now okay so what you do if you've lost something you're looking for go back to the lower power re-centered what you're looking for and then go back up to the next highest power remember al
