Remove CW Safety Cap at the end of CW Shaft. With the wider opening towards the shaft end,
guide CW through the shaft. Use the CW Locking Screw to hold the CW in place. Place Safety Cap back
onto the shaft. ZEQ25 comes with a 10.4 lbs (4.7kg) counterweight. It should be able to balance a total
payload of about 13 lbs (6kg) for a 6” diameter telescope. An optional CW or extension bar is needed for a
heavier payload or a larger diameter Telescope.
STEP 7 Attach and Balance an OTA on the Mount Connect Cables
After attaching an OTA and accessories to the mount, the ZEQ25 mount must be balanced in both
R.A. and DEC axes to ensure minimum stress on the mount (such as gears and motors inside).
CAUTION: The telescope may swing freely when the R.A. or DEC Gear Switch is released. Always
hold on to the OTA before you release the gear switch to prevent it from swinging. It can cause
personal injury or damage to the equipment.
