Object?” Press ENTER to slew the telescope to the
coordinates. Press ESC to exit.
Selecting a user defined object
1. Press the USER shortcut key. The screen will display
“User Object / Recall Object”. Press ENTER.
2. 2. Use the scroll keys to browse through the list of
pre-defined objects indexed from 1 to 25. Select the
number representing the object you wish to view,
then press ENTER to display the object’s coordinates.
Press the ENTER key again to proceed.
3. The screen will now display “View Object?”
• Press ENTER to slew the telescope to the selected
object.
• Press ESC to exit.
5. Configuring Hand
Controller and
Mount Settings
The SETUP shortcut key is the entry point for configuring
many aspects of the mount and hand controller. The different
types of functions available are listed below, along with their
respective purposes. Press the SETUP key to access them.
5.1 Date, Time, Site, Time Zone, and Daylight
Saving Time
1. Date – Allows you to change the date entered at the
initial setup.
2. Time – Allows you to change the current time.
3. Observing Site – Allows you to change the current
location settings.
4. Daylight Saving – Allows you to change the Daylight
Saving option.
5. Alignment – Allows you to re-perform the 1-star,
2-star, or 3-star alignment for GoTo operation with out
restarting the mount.
5.2 Hand Controller Display, Keypad, and Beeper
1. Access the menu “Setup \ Handset Setting” and press
the ENTER key.
2. Use the scroll keys to select “LCD Contrast,” then use
the left/right direction keys to adjust the contrast of the
LCD text characters.
3. Use the scroll keys to select “Beep Volume,” then use
the left/right direction keys to adjust the volume of the
beeper.
4. Use the scroll keys to select “LED Backlight,” then
use the left/right direction keys to adjust the LED
brightness of the hand controller keys (buttons).
5. Use the scroll keys to select “LCD Backlight,” then use
the left/right direction keys to adjust the brightness of
the LCD screen’s backlight.
6. Press ESC to exit the adjustment.
5.3 Backlash Compensation
Backlash is a delay in motorized motion of the mount due to
slack between gears. This delay, or hesitation, is experienced
when the slewing direction is reversed on one or both axes
of motion using the direction keys on the hand controller. So
when you’re looking at an object in the eyepiece, it will not
move immediately upon pressing a direction key – there will
be a lag time.
The SynScan hand controller can compensate for backlash by
commanding the mount to slew at a higher speed for a specific
amount of distance when the user revers es direction with the
direction keys. With such backlash compensation you’ll get a
faster response from the mount.
This function allows you to insert a value for each axis to com-
pensate for slewing backlash experienced on that axis. For
improved pointing accuracy, it is important that the backlash
value is set to be equal or greater than the actual amount of
backlash between the gears. If the actual amount of backlash
is unknown, we recommend that you set the value to 5000
(approximately equivalent to 0.2°). First set the value for R.A.
backlash, then press ENTER to set the value for DEC.
• Access the menu “SETUP / Backlash” and press the
ENTER key.
• The screen will display “Azm = XoXX’XX” ” or “RA =
XoXX’XX” ”. Use the Left/Right keys to move the cursor
and use the numeric keys to fill in a number at the cursor
position to input the amount of backlash in the azimuth
or R.A. axis. Press the ENTER key to finish the input and
proceed to the next step.
• The screen will display “Alt = XoXX’XX” ” or “Dec =
XoXX’XX” ”. Fill in the amount of backlash in the altitude
axis or Dec. axis and then press the ENTER key.
Notes:
• Set the backlash value to 0 for an axis to disable
backlash compensation for that axis.
• Backlash compensation is only active for computerized
GoTo slewing, not for manual slewing with the direction
buttons.
5.4 Tracking rate
The mount can track at several different rates, which you
select depending on the type of object(s) you’ll be observing
or photographing.
1. Access the menu “SETUP \ Tracking” and press the
ENTER key.
2. Use the scroll keys to browse the various options, and
press the ENTER key to pick one.
• Sidereal Rate:
This is the default tracking rate. Activates
tracking at sidereal rate (R.A. tracking) for observing/
photographing stars, deep-sky objects, and planets.
• Lunar Rate: Activates tracking at lunar rate (R.A. tracking)
for observing/photographing the Moon.
• Solar Rate: Activates tracking at solar rate (R.A. tracking)
for observing/photographing the Sun.
