Red Dot FinderĀ : The LED illuminates a pin-hole at the focus of the lens. The eye sees an image of the pinhole at infinity. You use the finder with both eyes open, one eye looking into the lens, the other looking at the sky. Your brain superimposes the image of one eye upon that of the other and the visual effect is that you see a red dot placed on the sky.
