3. The hand controller will scroll a warning message about
the danger of viewing the Sun with a telescope without
a properly fitted solar filter. Press ENTER to confirm you
have read the warning message and proceed to the next
step. Press ESC to return to the previous step.
4. The LCD screen will display “Enter Location” on the first
line, and longitude and latitude values on the second line.
Enter the latitude and longitude of your current location using
the numeric keypad and scroll buttons. If you do not know the
latitude and longitude coordinates of your viewing location,
consult an atlas or look them up on the internet (i.e., search
“[your location] coordinates”).
• Use the scroll keys to choose between E or W (for
longitude) and N or S (for latitude).
• Press ENTER to confirm the entered coordinates and
proceed to the next step.
NOTE: Latitude and longitude coordinates must be
entered in degrees and arcminutes. If your atlas or other
reference source provides coordinates in decimal val­
ues (i.e., latitude = 36.95 N), you must convert that into
degrees and arcminutes (i.e., latitude 36.95 N = latitude
36°57’ N). There are 60 arcminutes in 1 degree.
5. Enter the current time zone in which you are observing
in hours (see Appendix B), using the scroll keys and
numeric keypad (+ for East, – for West) The “+” sign is
used for time zones in the Eastern Hemisphere (Europe,
Africa, Asia, Oceania), while the “-” sign is used for time
zones in the Western Hemisphere (North and South
America). So for Pacific Standard Time (PST) you would
enter -08:00. Press ENTER to confirm.
6. Enter the date in the format mm/dd/yyyy using the
numeric keypad. Press ENTER to confirm your choice.
7. Enter your current local time using the 24 hour time
mode (e.g., 2:00 p.m. = 14:00). Press ENTER to view the
time you entered. If the time is incorrect, press ESC to go
back to the previous screen. If the time is correct, press
ENTER to confirm.
8. When “Daylight Saving?” is displayed, use the scroll keys
to select “Yes” or “No”. “YES” indicates the time entered
in the previous step is Daylight Saving time, while “NO”
indicates the time entered is Standard time. Press the
ENTER key to confirm and proceed to the next step.
9. Now the screen will display “Begin Alignment?” and ask
you to select 1) YES or 2) NO. Press “1” or ENTER to
start the alignment process. Press “2” or ESC to skip the
alignment process.
NOTE: The hand controller LCD’s red illumination will dim
and the keypad backlighting will turn off if idle for 30 sec­
onds. Pressing any key turns the lighting back on.
GoTo Star alignment
In order for your StarSeeker III GoTo telescope to accurately
locate and point to objects in the sky, it must first be aligned
on known positions (stars) in the sky. With that information, the
mount can create a model of the sky and of the movements of
astronomical objects.
There are two methods for aligning your StarSeeker III tele-
scope, and they are very similar: Brightest Star Alignment and
2-Star Alignment. Both involve identifying and pointing the
telescope to two different bright stars in the night sky. Both
