The real image of the light refracted by the objective lens is at the focus of the rear of the eyepiece (near the rear of the human eye). This image is a virtual image to the eyepiece, so it is refracted to form an enlarged erect virtual image. The magnification of the Galileo telescope is equal to the ratio of the focal length of the objective lens to the focal length of the eyepiece. The advantage is that the mirror is short and can be positive, but its field of view is relatively small.
