telescope, they are only valid for that exact location. To save land objects, once again center the desired object in the eyepiece. Scroll down to the "Save Land Obj" command and press ENTER. The display will ask you to enter a number between 1 and 200 to identify the object. Press ENTER again to save this object to the database. To replace the contents of any of the user defined-objects, simply save a new object using one of the existing identification numbers; the telescope will replace the previous user-defined object with the current one. Get R.A./DEC - Displays the right ascension and declination for the current position of the telescope. Goto R.A./Dec - Allows you to input a specific R.A. and declination and slew to it. Hint: To store a set of coordinates (R.A./Dec) permanently into the database, save it as a User-Defined Object as described above. To use Precise GoTo: 1. Press the MENU button and use the Up/Down keys to select Precise GoTo. • Choose Database to select the object that you want to observe from any of the database catalogs listed or; • Choose R.A./DEC to enter a set of celestial coordinates that you wish to slew to. 2. Once the desired object is selected, the hand control will search out and display the closest bright star to your desired object. Press ENTER to slew to the bright alignment star. 3. Use the direction buttons to carefully center the alignment star in the eyepiece. 4. Press ENTER to slew to the desired object. Identify Identify Mode will search any of the mount's database catalogs or lists and display the name and offset distances to the nearest matching objects. This feature can serve two purposes. First, it can be used to identify an unknown object in the field of view of your eyepiece. Additionally, Identify Mode can be used to find other celestial objects that are close to the objects you are currently observing. For example, if your telescope is pointed at the brightest star in the constellation Lyra, choosing Identify and then searching the Named Star catalog will no doubt return the star Vega as the star you are observing. However, by selecting Identify and searching by the Named Object or Messier catalogs, the hand control will let you know that the Ring Nebula (M57) is approximately 6° from your current position. Searching the Double Star catalog will reveal that Epsilon Lyrae is only 1° away from Vega. To use the Identify feature: • Press the Menu button and select the Identify option. • Use the Up/Down scroll keys to select the catalog that you would like to search. • Press ENTER to begin the search. Note: Some of the databases contain thousands of objects and can therefore take several minutes to return the closest objects. Precise GoTo The mount has a Precise Goto function that can assist in finding extremely faint objects and centering objects closer to the center of the field of view for astroimaging. Precise GoTo automatically searches out the closest bright star to the desired object and asks the user to carefully center the star in the eyepiece. The hand control then calculates the small difference between its GoTo position and its centered position. Using this offset, the mount will then slew to the desired object with enhanced accuracy. 22 I
