8. Balance payload: After attaching the scope and
accessories, the mount head assembly must be
balanced in both DEC and RA axes to ensure
minimum stresses on the mount driving mechanism.
CAUTION: The telescope may swing freely when the
R.A. or DEC Gear Switch is disengaged. Always hold
on to the mount and/or telescope assembly before
releasing the Gear Switches to prevent it from
swinging, which can cause personal injuries and/or
equipment damages.
Set the mount at Zero Position. Disengage both RA
and DEC gear switches and move the mount to
horizontal position to check balance. Return to Zero
Position for balance adjustment. Balance the DEC axis
by moving the scope with accessories back and forth
in the mount saddle or within the scope mounting
rings. Balance the assembly in R.A. axis by moving CW
along its shaft. Repeat the process until both DEC and
RA axes are balanced.
CAUTION: The balancing process MUST be done with
Gear Switch at the total disengaged position!
Otherwise it might damage the worm system.
Return the mount to Zero Position after balancing
and engage gear switches.
9. Connect cables: Use the short RJ11 cable to connect
the DEC control unit to the DEC port of the RA/main
control unit.
Connect the Go2Nova
®
8409 Hand Controller to the
HBX port on the main unit. Plug in a 12V DC power
supply to the DC12V IN socket next to the HBX port.
Plug optional GPS module into the iPORT with a
coiled cable. When powering on, GPS ON sign should
be displayed at the upper right corner of the hand
controller. You may disconnect the GPS module after
it picks up satellites signals and displays GPS OK. (It
takes about 1 to 2 minutes in normal conditions).
10. Set controller: Press the MENU button; then
“Settings” => “Set Time & Site”.
Enter the current date or waiting for the GPS
connected to the satellites. Enter the time zone
offset to the UTC; for examples:
 Boston is “UTC -300 minutes”
 Los Angeles is “UTC -480 minutes”
 Rome is “UTC +060 minutes”
 Sydney is “UTC +600 minutes”
Toggle the Daylight Saving Time (DST) between N(No)
and Y(Yes) using arrow key. Move the cursor to the
end of screen to select the Northern or Southern
Hemisphere.
[TIPS: All time zones in N. America are “UTC -XXX
minutes”. Latitude and longitude coordinates can be
obtained from GPS-equipped devices (navigator,
phone), or from internet, if you are entering them
manually. “W/E” = western/eastern hemisphere;
“N/S” = northern/southern hemisphere; and “d” =
degree; “m” = minute; and “s” = second. Use arrow
and number keys to enter location information.]
11. Polar alignment: A CEM26 mount may be equipped
with an iPolar
TM
electronic polar scope or an
AccuAlign
TM
optical polar scope. Please refer to
CEM26 User’s Manual for detailed polar alignment
procedures.
