STEP 3. Attach the iEQ45 Mount

Locate the Azimuth Adjustment Knobs (next to the Bubble Level Indicator) and retract them to allow enough clearance for the mount to fit on the tripod head. Unscrew the three (3) Azimuth Locking Screws shown in Figure 8 and be careful not to lose the plastic washers; they will be needed to secure the mount. Place the mount onto the Tripod Head with the Bubble Level Indicator on top of the Alignment Peg as shown in Figure 9. Place the Teflon washers and the three (3) Azimuth Locking Screws back and tighten the screws. Level the tripod base by adjusting the individual legs. You may use the built-in Bubble Level Indicator or an external torpedo level to check leveling.

STEP 4. Set the Location Latitude

This step requires you to know the latitude of your current location. This can be found from your 8407 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.

Unscrew the Latitude Adjustment Lever from the Latitude Adjustment Knob as shown in Figure 6. Turn the Latitude Adjustment Knob to set your current latitude in the Latitude Mark Window, using the Latitude Adjustment Lever for a fine adjustment, if needed. At this point, with the mount level 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.

CAUTION: For safety reasons, always adjust the latitude without an OTA and/or counterweights installed. Also, it is much easier to make this precise adjustment without a load on the axis being adjusted.

STEP 5. Attach Counterweight (CW) Shaft

Unscrew the CW shaft from the top of the mount as shown in Figure 10(a) and thread it into the opening of the DEC axis as shown in Figure 10(b).
