These are all genuine fission tracks with a clear etch pit in reflected light, and randomly oriented tail in transmitted light. You can drag the view with your mouse and zoom in or out with the + and - buttons in the top left of the view. You can also change focus with the vertical slider in the top left of the view, or with your mouse wheel. This allows you to scroll through the image stack, with reflected light images at the top and transmitted light images below. You can see the tracks are shown here with a black square around them. Some of these squares have yellow highlights; these have extra comments that you can see by hovering your mouse pointer over them.
