For a lot of us, aiming the telescope at the right spot in the sky can be challenging. A standard finder scope yields a magnified, upside-down image compared to the naked-eye view.It's a non magnifying sighting device that superimposes a tiny, LED-powered red dot, focused at infinity, on the sky. The dot, which is centered in a wide 10 degree upright field of view, shows exactly where your telescope is pointed. The brightness of the red dot is adjustable to suit your preference. Thumbwheels allow fine positioning of the dot horizontally and vertically for precise alignment with the main telescope.
