If a small motor is attached to the equatorial mount, this tracking can be performed automatically. These motor drives are available for most Meade equatorially mounted telescopes. The Meade LX200 computer control system permits the telescope to be mounted in an altazimuth orientation, while motors, directed by an internal microprocessor, on both telescope axes follow astronomical objects with extreme precision. The LX200 system further allows the observer to input an object's catalog number or celestial position to a handheld keypad, press GO TO, and watch as the telescope automatically moves to the object and centers it in the telescope's field of view. These terms form a basic part of the jargon associated with optics and telescopes, a jargon that even the most novice telescope user can understand.
Resolution is a qualitative expression of how much detail can be observed through a given telescope.
Telescopes are said to be of high-resolution if they are manufactured to optical standards that permit a level of visible detail consistent with the aperture and optical design of the instrument. This telescopic image of a star, consisting of the Airy disc and its surrounding rings of light, is called the diffraction image . Resolving power is the ability of a telescope to separate two closely-located starpoints. The concept of the diffraction image is important because it allows the telescope user to rate the quality of the telescope's optical system. The larger a telescope's aperture, the greater its ability to show two adjacent stars as separate, distinct images, rather than as one overlapping image.
