Selecting Objects from the Catalog

To select a deep-sky object, press either the Messier (1), Caldwell (2), or NGC (4) button on the hand controller to choose the desired catalog.  Enter the number of the object in the catalog.  Messier and Caldwell objects require 3 digits, NGC objects require 4 digits.  To select M13, for example, you must enter 013; for NGC253, you must enter 0253.

Press ENTER and the telescope will slew to the selected object.  Press UNDO to select a new object.
