6.Polar Alignment: In order for an equatorial mount to track properly, it has to be accurately polar aligned. The mount has been set to face north (in Northern Hemisphere) as indicated in Step 1. The latitude has been roughly set, as indicated in Step 3.
Take off the Polar Axis Cover and Polar Scope Cover. Look through the polar scope eyepiece to locate the Polaris. If the hole is blacked by the DEC axle, use the ▲ or ▼ button on the hand controller to turn the DEC axle to unblock the Polar Scope view. (You may use the number button to change the slewing speed. 9 for MAX speed). Loosen the two Azimuth Locking Screws and adjust the Azimuth Adjustment Knobs to do a fine adjustment of the mount to center the Polaris in the azimuth direction. Tighten the locking screws to secure the mount. Loosen four Latitude Locking Screws on the side of the mount, turning the Latitude Adjustment Knob to adjust the latitude (altitude). Use the Lever for a fine adjustment to center the Polaris along the latitude direction.
With iOptron’s AccuAligningTM Polar Scope and Quick Polar Alignment procedure, you can do a fast and accurate polar alignment. Please refer to
7.Install Counterweight: iEQ30 comes with one 10lb (4.5kg) counterweight (CW) and an extension shaft. Use CW or CW and extension shaft to balance your OTA (Optical Tube Assembly). Tighten the CW Locking Screw to hold the CW in place. Tighten the CW Safety Screw.
8.Attach and Balance an OTA on the Mount: After attaching an OTA and accessories to the mount, the iEQ30 must be balanced in both R.A. and DEC to ensure minimum stress on the mount (such as gears and motors inside).
CAUTION: The telescope may swing when the R.A. or DEC clutch is released. Always hold on to the OTA before you release the clutch to prevent it from swinging. It can cause personal injury or damage to the equipment.
Balance the mount in DEC axis
Release the R.A. Clutch and rotate the R.A. axis to place the DEC axis in the horizontal position, as shown in Figure 5(a), and then tighten the R. A. Clutch. The OTA can be on either side. Then release the DEC Clutch and rotate the OTA to a horizontal position as shown in Figure 5(b). If the OTA has a tendency to rotate about the DEC axis, you will have to slide the OTA forward or backward to balance it in the horizontal position about the DEC axis. When the OTA is balanced horizontally, tighten the DEC Clutch.
Balance the mount in R.A. axis
Release the R.A. Clutch. If the DEC axis stays in the horizontal position, as shown in Figure 5(a), it means the R.A. axis is balanced. Otherwise, release the CW Locking Screw and move the CW as required to balance the R.A. axis. Tighten the CW Locking Screw.
