16. Depending on how much detail you want to see, 400X (as Chris commented) is definitely sufficient. Remember, the lens (es) under/over the stage are labeled 10X, 20X, 40X, etc., while the eyepiece is generally 10X or perhaps 20X (multiplying the two together gives the final magnification).They're quite complicated (and expensive (average $294,000, per Google), and generally used for much higher magnifications. I also think you need specially treated specimens, not just a slice of onion. To this non-expert, those white spots look like thin places in your sample, seen in a light microscope. $\endgroup$ –Cells are drawn but do not look clear.
