Definition:
Transit is the time when the Sun, Moon, or other celestial object crosses an observer's meridian, i.e., the time when an object is at its highest point in the sky on any given date.
WARNING! Never use your Meade® LX200R
Telescope to look at the Sun! Looking at or near the Sun will cause instant and irreversible damage to your eye. Eye damage is often painless, so there is no warning to the observ- er that damage has occurred until it is too late. Do not point the tele- scope or its viewfinder at or near the Sun. Do not look through the telescope or its viewfinder as it is moving. Children should always have adult supervi- sion while observing.
Identify: An exciting feature for an observer who wants to scan the night sky and start exploring. After the telescope has been properly aligned, use the AutoStar II Arrow keys to move about in the sky. Then follow this procedure:
Important Note: Only use the Arrow keys to move the telescope during the Identify procedure. Do not loosen the telescope locks or move the base or alignment is lost.
1.When a desired object is visible in the eyepiece, keep pressing MODE until the “Select Item: Object” menu is displayed. Press ENTER to select this menu.
2.Scroll through the Object menu options until the “Object: Identify” screen appears.
3.Press ENTER. AutoStar II searches the libraries for the identity of the object being observed.
4.If the telescope is not directly on an AutoStar II library object, the nearest library object is located and displayed on the screen. Press GO TO and the telescope slews to that object.
Browse: Allows you to search the library for objects with certain parameters, much like a search engine. "Edit Parameters" lets you set various parameters for the search, such as: Object Type, Minimum Elevation, Largest, etc. Once you have set the param- eters of the search, select "Start Search" and press ENTER. AutoStar II will display the results of the search.
