There are two threaded holes on the tripod head for alignment peg installation. The Alignment Peg
may be moved to the opposite position shall the mount hit the tripod leg when used at a high latitude.

STEP 4. Attach the CEM25 Mount
Back out both Azimuth Adj. Knobs to allow enough clearance
inside the chamber. Position the mount on the tripod head with the
Alignment Peg in between the two Azimuth Adj. Knobs. Thread the
Center Rod into mount to secure it with tripod. Tighten the Tray Locking
Knob to fully spread the tripod legs. Adjust the tripod legs to level the
mount using the Level Bubble.
STEP 5. Adjust Latitude
This step requires you to know the latitude of your current
location. This can be found from your 8408 hand controller after the
embedded GPS receives the signal from the satellites. It also can be
easily found on the Internet, with your GPS navigator or a GPS capable
cell phone. You will have to change this latitude setting every time you significantly change your night sky
viewing location. This setting directly affects the mount’s tracking and GOTO accuracy.
Slightly loosen the Latitude Locking T-bolts. Turn Latitude Adjust Knob to adjust the latitude until the
arrow points to your current latitude on the Latitude Indicator (see Figure 8b). Relock the Latitude Locking
T-bolts. At this point, with the mount leveled and pointed north, and the latitude set, the Polar Axis (R.A.
axis) should be pointing very close to the NCP and Polaris. This alignment accuracy will be sufficient for
visual tracking and short duration piggy-back (camera mounted on top of the OTA) astrophotography.
STEP 6. Install Counterweight (CW) Shaft
(1) Remove CW Shaft Locking Screw from the CW Mounting Nose.
(2) Insert CW shaft into the CW Mounting Nose as indicated in Figure 11b.
(3) Lock it using CW Shaft Locking Screw from the other side of the CW Mounting Nose. Tighten the
Front CW Positioning Screw which is located in front of the CW Mounting Nose.
