Get Ra/Dec; Go To Ra/Dec; Identify - Celestron NEXSTAR 102GT Manuel D'instructions

To go to any of the user defined objects stored in the database, scroll
GO TO OBJECT:
down to either "Go To Sky Obj" or "Go To Land Obj" and enter the number of the object
you wish to select and press ENTER. NexStar will automatically retrieve and display
the coordinates before slewing to the object.
To replace the contents of any of the user defined objects, simply save a new object using one of the
existing identification numbers; NexStar will replace the previous user defined object with the current one.
GET RA/DEC: Displays the right ascension and declination for the current position of the telescope.
GO TO RA/DEC: Allows you to input a specific R.A. and declination and slew to it.

IDENTIFY

Identify Mode will search any of the NexStar 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 a minute
or two to return the closest object.
PRECISE GO TO
The NexStar has a Precise Go To function that can assist in finding extremely faint objects and
centreing objects closer to the centre of the field of view for high magnification viewing. Precise Go To
automatically searches out the closest bright star to the desired object and asks the user to carefully
centre it in the eyepiece. The Hand Control then calculates the small difference between its Go To
position and its centreed position. Using this offset, the telescope will then slew to the desired object
with enhanced accuracy. To use Precise Go To:
> Press the MENU button and use the Up/Down keys to select Precise Go To.
> Choose Database to select the object that you want to observe from any of the
database catalogs listed.
> Choose RA/DEC to enter a set of celestial coordinates that you wish to slew to.
> 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.
> Use the direction buttons to carefully centre the alignment star in the eyepiece.
Press ENTER to slew to the desired object.
