_______________________________________________________________________ The diatom Achnanthes 40X

As the power rises, live microphotography gets harder, since subject movement is a real problem. This is a well-aligned diatom on a commercial stained prepared slide. The fine striae (grooves) visible on the surface of the frustule (shell) indicate resolution is quite healthy, and they are easier to examine and count than visually under the microscope. The Wild Fluotar objective is relatively new, at around 20 years old. Better objectives are available, but, as we have previously said, at a price.
