Goto R.A/ Dec - Allows you to input a specific R.A. and declination and slew to it. Helpful Hint To store a set of coordinates (R.A./Dec) permanently into the database, save it as a User Defined Object as described above. Identify Identify Mode will search any of the telescope'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 telescope 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 astrophotography and CCD imaging. Precise Goto automatically searches out the closest bright star to the desired object and asks the user to carefully center it in the eyepiece. The hand control then calculates the small difference between its goto position and its centered position. Using this offset, the telescope will then slew to the desired object with enhanced accuracy. 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 RA/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. Scope Setup Features Setup Time-Site - Allows the user to customize the telescope's display by changing time and location parameters (such as time zone and daylight savings). Anti-backlash - All mechanical gears have a certain amount of backlash or play between the gears. This play is evident by how long it takes for a star to move in the eyepiece when the hand control arrow buttons are pressed (especially when changing directions). The CGE PRO anti-backlash features allows the user to compensate for backlash SCOPE SETUP SET UP TIME-SITE ANTI-BACKLASH FILTER LIMITS DIRECTION BUTTONS GOTO APPROACH AUTOGUIDE RATES OTA ORIENTATION MERIDIAN MOUNT SETTINGS RA LIMITS RA POSITIVE RA NEGATIVE DEC POSITIVE DEC NEGATIVE RA BUTTONS DEC BUTTONS RA APPROACH DEC APPROACH RA RATE DEC RATE NORMAL EAST WEST FAVOR CURRENT FAVOR WEST FAVOR EAST DISABLED CONE VALUE DEC INDEX RA INDEX 26

Goto R.A/ Dec
- Allows you to input a specific R.A. and declination and slew to it.
To store a set of coordinates (R.A./Dec) permanently into the database, save it as a
User Defined Object
as
described above.

Identify Mode
will search any of the telescope'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

object. Press ENTER to slew to the bright alignment star.
3.
Use the direction buttons to carefully center the alignment star
