To collect light and form an image, reflecting telescopes use a concave primary mirror. The Newtonian reflector uses a small secondary mirror located to the side of the main telescope tube in order to reflect light and create an observable image. The AutoStar handbox controls a DS-2000 telescope and allows the user to automatically move any of the 1,400 objects stored in the database. Users can also manually enter coordinates of any celestial object. AutoStar also has a glossary of astrological terms at the user's disposal, and it will calculate the best eyepiece for optimal viewing.
