DS-2000 Series Reflecting and Refracting Telescopes
Refracting Telescopes use a large objective lens as their primary light-collecting element. Meade refractors, in all models and apertures, include achromatic (2-element) objective lenses in order to reduce or virtually eliminate the false color (chromatic aberration) that results in the telescopic image when light passes through a lens. Reflecting Telescopes use a concave primary mirror to collect light and form an image. In the Newtonian type of reflector, light is reflected by a small, flat secondary mirror to the side of the main tube for observation of the image.

Refracting Telescope
In the refracting telescope, light is collected by a 2-element objective lens and brought to a focus at F.

MENUS AND MENU OPTIONS
Object Menu
Almost all observing with Autostar is performed using the Object menu category. (NOTE: Exceptions include Guided Tour and Landmark Survey. ) See GO TO SATURN, page 20, for an example of observing using the Object menu. An Autostar database is a list of viewable objects, such as stars, planets, comets, nebulae, and so forth. When one of these objects is selected from a database, Autostar moves your telescope (if properly aligned) and points it at the selected object. The Object Menu options include: Solar System is a database of the eight planets (Earth is not included) in order out from the Sun, followed by the Moon, asteroids, and comets. Constellation is a database of all 88 Northern and Southern Hemisphere constellations. When this menu option is chosen and a constellation name appears on the first line of the screen, press GO TO once to change the second line to the name of the brightest star in the constellation. Use the Scroll keys to cycle through the list of stars in the constellation, from brightest to dimmest. Deep Sky is a database of objects outside our Solar System such as nebulae, star clusters, galaxies, and quasars. Star is a database of stars listed in different categories such as named, double, variable, or nearby. Satellite is a database of Earth-orbiting objects such as the International Space Station, the Hubble Space Telescope, Global Positioning System (GPS) satellites, and geosynchronous orbit satellites. User Objects allows the user to define and store in memory deep-sky objects of specific interest that are not currently in the Autostar database. See "Appendix B" for more information.
