You can then look and/or take an image at 400x.. To do this, rotate the knurled knob to the right all the way until it stops.
Then, rotate the knob slightly to the left until the object is sharply focused. Hold the HDM steady (this is a little more difficult
than at 20x) and push the "click" button to take the image. For objects that you cannot put the HDM over or on, you can pick
up the microscope and point it at an object up to a few feet away. To do this kind of viewing and or imaging you must hold the
HDM as steady as possible. Results will come out best when you use 20x and the closer to the object the better.
To see additional examples of images taken with the HDM, please go to the Celestron website.
