To use this, you hold the camera about 1-1/2 feet from your eyes keeping both eyes open. You hold it so your dominate eye looks through the scope and position the red-dot over the target. With both eyes open, you can see the entire sky so finding your target is easy, just like pointing your finger at it. You can set this up on the top of a telephone pole and used another camera. You can see the dot over the pole and also see in in live view on the LCD.When use these on two other zoom cameras. With practice, you can see something as small as a high flying jet and from picking the camera up, have it in the frame in about 1 second. Using the viewfinder or LCD is much slower and sometimes next to impossible.
