These images were gathered in two basic ways. Some of the lowest power images are scans taken by a scanner. These don't have much detail, but they give you a feel for what the overall slide looks like. This is really important for slides in which the sample is too big to see the whole thing under low power. For example, the lymph node is WAY too big to see at low power. When looking at the scanned image, you can see the whole thing - the low power image it just looking at about the part I have put a box around. In fact, you should look at it against some white paper before putting it on the stage of your microscope. Not all slides will have a scanned image.

The other images were all taken with Dr. Hirt's really nice microscope (thank you Dr. Hirt) that has an attachment to slip a digital camera onto. This microscope has the same power lenses that yours have. But the camera has a zoom of its own, and I used it to zoom in a bit on many images to get rid of a black circular border. So, the images you're seeing here are a bit bigger than those you see through your own microscope. It's not a lot and you might not even notice it unless you were looking at both of them at the same time.

An exception to that is on some of the "HIGH" power images. On many of them I zoomed all the way in to get detail on one thing or another. There is no way you'll be able to get that kind of detail on your microscopes, but I think those images are of value anyway. For example, here's an image of the trachea at normal high power, and here is one with the camera zoomed all the way in. Notice that at normal high the cilia look like a fuzz and with the zoomed image you can actually see them.
