Notice that it has a metal ring at the center. Also notice that it has four buttons to press. One at the left, one at the right and two at the bottom (up and down). By pressing these buttons you can move the telescope in the corresponding direction. Your goal is to find the sun and track it down in the center ring. This will power up the surroundings. The best way to do this is waiting until the sun comes bye and then simply "catch" it in the center ring.

Go round to the telescope on the other side. Zoom in and you should see the sun whizzing past (although you may have to wait for it to arrive). You task is to track the sun. Use the half rings at the bottom to go up and down and those on the right and left of the lens to track across. To speed up, double click. To slow down or stop, click in the opposite direction. When you finally get the sun to stay in the centre of the lens, you will hear the generator power up.
