This allows the battery to have a red dot appear when it is turned on. Then try the finder by toggling it with a small rotary control on the side. Look through the hole on the front of the crosshair and you should see a red dot and be able to lighten or darken with this rotary control, which is also an on/off switch. Now your range as normal, but put the red dot finder on instead of the usual optical finder. Point the telescope at something like a TV antenna or chimneyanything of that size will do, and the farther away the better. Looking through a low power eyepiece (25mm is ideal) you find your subject by adjusting your telescope and the focus of your object. Position the handle using the slow-motion controls so that the subject is in the center of the view. Position the crosshair so that the red dot is exactly on the object you were looking at. You can customize it with two larger wheels. The one on the right side in front has a left/right direction, and the one on the back bottom does up and down. Turn it off and wait until darkNow you use it by switching the finder to and then looking through the finder so that the red dot lines until you are going to observe through the telescope. When the red dot is directly above a star or planet, it should be exactly in the center of the eyepiece view. Be sure to turn it off when you find it to save the battery.
