2.Close your right eye and sight an object with your left eye, rotate the center focus wheel until the image is sharp and clear.
3.Open your right eye and close your left eye. Rotate the right eyepiece until the object sighted is sharp and clear.
4.Both sides(eyes) are now in focus and you will need to use only the center focus wheel to focus on the other objects.
