An ingenious invention: rear sight and front sight in one device! Without optical magnification, the Starpointer allows you to quickly aim at celestial objects with both eyes. An artificial star, generated by a red LED, is projected into the field of view via a mirror. This makes it much easier to find objects. The brightness can be adjusted within a wide range. The Starpointer is also a good addition to normal optical viewfinders. A 3-volt battery is required for the power supply. Two adapters are included with the StarPointer, with which they can be adapted to the standard Celestron Schmidt-Cassegrains.
