STEP 3. Attach the ZEQ25 Mount

Retract 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 2 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 4. 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 Figure 9. Attach a mount 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 7b). 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.
