Crop of an image through the eyepiece showing red and white blood cells at 400x magnification. The overall color is slightly rusty, but not red. Many of the red blood cells are burst, but some retain their doughnut shape. A few white blood cells are visible, larger than the red cells and with a visible nucleus.
