Dear Gabrielle, Hi! Professional video cameras for microscopes are expensive (thousands of dollars). However, I have seen some of my students actually take serviceable still pictures of cells simply by focusing their cell phone cameras through the ocular lens of a microscope. Have you tried this? You may actually have some luck also by using a camcorder. If these do not work, I could only suggest trying to Google used cameras for microscopes and see what you could come up with.
