Celestron NEXSTAR 102GT Manuel D'instructions page 14

The Hand Control display will then ask for the following information:
LOCATION The NexStar will display a list of cities to choose from. Choose the city from the
database that is closest to your current observing site. The city you choose
will be remembered in the Hand Control's memory so that it will be automatically
displayed the next time an alignment is done. Alternatively, if you know the exact
longitude and latitude of your observing site, it can be entered directly into
the Hand Control and remembered for future use as well. To choose a location city:
Use the Up and Down scroll keys to choose between City Database and Custom Site. City Database
will allow you to select the closest city to your observing site from a list of either international or U.S.
locations. Custom Site allows you to enter the exact longitude and latitude of your observing site. Select
City Database and press ENTER.
Use the Up and Down Scroll buttons to choose your current state (or country if International locations
was selected) from the alphabetical listing and press ENTER.
Use the Up and Down Scroll buttons to choose the closest city to your location from the displayed
list and press ENTER.
TIME Enter the current time for your area. You can enter either the local time (i.e. 8:00),
or you can enter military time (i.e. 20:00).
Select PM or AM. If military time was entered, the Hand Control will bypass this step.
Choose between Standard time or Daylight Savings time. Use the Up and Down scroll buttons (10) to
toggle between options.
Select the time zone that you are observing from. Again, use the Up and Down buttons (10) to scroll
through the choices. For time zone information, refer to the Time Zone map in the appendix of this manual.
DATE Enter the month, day and year of your observing session. The display will read: mm/dd/yy.
If the wrong information has been input into the Hand Control, the UNDO button will act
as a backspace allowing the user to re-enter information.
The next time that your NexStar is aligned, the Hand Control will automatically display
the last location (either a city or longitude/latitude) that was entered. Press ENTER to
accept these parameters if they still apply. Pressing the UNDO button will allow you
to go back and select a new city location or longitude/latitude.
3. Use the arrow buttons on the Hand Control to slew (move) the telescope towards any bright
celestial object in the sky. Align the object with the red dot of the finderscope and press ENTER.
4. If the finderscope has been properly aligned with the telescope tube, the alignment star should
now be visible inside the field of view of the eyepiece. The Hand Control will ask that you centre
the bright alignment star in the centre of the eyepiece and press the ALIGN button. This will
accept the star as the first alignment position. (There is no need to adjust the slewing rate of
the motors after each alignment step. The NexStar automatically selects the best slewing rate
for aligning objects in both the finderscope and the eyepiece).
5. For the second alignment object, choose a bright star or planet as far as possible from the first
alignment object. Once again use the arrow button to centre the object in the finderscope and
press ENTER. Then once centreed in the eyepiece press the ALIGN button.
6. Repeat the process for the third alignment star. When the telescope has been aligned to the final
stars, the display will read "Match Confirmed." Press UNDO to display the names of the three
bright objects you aligned to, or press ENTER to accept these three objects for alignment.
You are now ready to find your first object.
