5. Operating Instructions
This section outlines the basic steps for operating your iOptron CEM26 mount.
- Power On: Turn on the mount using the power switch. The hand controller will illuminate and display the initial boot screen.
- Site Information: Enter your current location (latitude, longitude) and time zone into the hand controller. This is crucial for accurate GoTo functionality.
- Polar Alignment (AccuAlign): Use the integrated AccuAlign optical polar scope to precisely align the mount's polar axis with the celestial pole. Follow the instructions displayed on the hand controller or refer to the detailed polar alignment guide in the full manual (available on the iOptron website).
- Star Alignment: Perform a 1-star, 2-star, or 3-star alignment using bright stars. This calibrates the mount's internal model for accurate pointing.
- GoTo Function: Select a celestial object from the hand controller's database (e.g., planets, stars, deep-sky objects). Press "GoTo" and the mount will automatically slew to the target.
- Tracking: Once an object is targeted, the mount will automatically begin tracking it across the sky, compensating for Earth's rotation.
- Slewing Speeds: Adjust the slewing speed using the hand controller's arrow keys for fine adjustments or rapid movement.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your iOptron CEM26 mount.
- Cleaning: Keep the mount free from dust and debris. Use a soft, dry cloth for cleaning the exterior. Avoid abrasive cleaners or solvents.
- Lubrication: The mount's internal gears are factory-lubricated. Do not attempt to lubricate internal components unless specifically instructed by iOptron support.
- Storage: When not in use, store the mount in its original carrying case in a dry, temperature-controlled environment to prevent moisture damage.
- Cable Inspection: Periodically inspect all cables for signs of wear or damage. Replace damaged cables immediately.
- Firmware Updates: Check the iOptron website periodically for firmware updates for the mount and hand controller. Keeping the firmware updated can improve performance and add new features.
7. Troubleshooting
This section addresses common issues you might encounter with your CEM26 mount.

- Verify the power source is providing the correct voltage (12V DC).
- Check the power cable for any damage.
- GoTo Inaccuracy:
- Re-check your site location (latitude, longitude) and time settings in the hand controller.
- Perform a precise polar alignment using the AccuAlign scope.
- Ensure your star alignment procedure was accurate and used bright, well-separated stars.
- Verify the mount is properly balanced with your telescope.
- Tracking Issues:
- Confirm accurate polar alignment.
- Check for any obstructions or cable snags that might impede smooth movement.
- Ensure the mount is not overloaded beyond its weight capacity.
- Hand Controller Not Responding:
- Disconnect and reconnect the hand controller cable.
- Restart the mount.
- Check for any bent pins in the hand controller port or cable.
