to use your hand control on a different NexStar model, the Select Model utility feature allows you to re-select the proper
NexStar model from the displayed list (see Select Model later in this section).
2. Use the Up and Down scroll keys to select AutoAlign if it is not already displayed, and press ENTER.
3. The telescope will then ask you to use the direction keys (3) to level the telescope tube and point the front of the
telescope towards north. North can be found by finding the direction of the North Star (Polaris) or by using a compass.
You do not need to point at the North Star, only the north horizon. Alignment only needs to be approximate, however a
close alignment will make the auto alignment more accurate. Once the telescope is in the north and level position, press
ENTER.
4. 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 controls 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. location. Custom Site
allows you to enter the exact longitude and latitude of your observing site. Select City Database and press
ENTER.
The hand control will allow you to choose from either U.S. or international locations. For a listing of U.S.
locations by state and then by city, press ENTER while United States United States United States United States is displayed. For international locations,
use the Up or Down scroll key to select International International International International and press ENTER.
To display a list of local cities, first select your state from the alphabetical listing (or a list of countries if
International locations was selected) and press ENTER.
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 Auto Aligned, the hand control will automatically display the last location
(either a city or longitude/latitude) that was entered. Pressing the UNDO button will allow you to go back and
select a new city location or longitude/latitude.
Based on this information, the NexStar will automatically select a bright star that is above the horizon and slew towards it. At
this point the telescope is only roughly aligned, so the alignment star should only be close to the field of view of the Star
Pointer finder. Once finished slewing, the display will ask you to use the arrow buttons to align the selected star with the red
dot in the center of the Star Pointer. If for some reason the chosen star is not visible (perhaps behind a tree or building) you
can press UNDO to select and slew to a different star. Once centered in the finder, press ENTER. The display will then
instruct you to center the star in the field of view of the eyepiece. When the star is centered, press ALIGN to accept this star
as your first alignment star. (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 Star Pointer and the eyepiece). After the first
alignment star has been entered the NexStar will automatically slew to a second alignment star and have you repeat the same
