Sky-Watcher AZ-EQ5 Telescope Mount User Manual

1. Introduction

The Sky-Watcher AZ-EQ5 is a highly versatile and innovative telescope mount designed for both visual observation and astrophotography. This hybrid mount offers the flexibility to operate in Alt-Azimuth (Alt-Az), Equatorial (EQ), or dual-Optical Tube Assembly (OTA) modes, making it suitable for a wide range of astronomical pursuits. This manual provides detailed instructions for the proper setup, operation, and maintenance of your AZ-EQ5 mount to ensure optimal performance and longevity.

2. Product Overview

The AZ-EQ5 mount incorporates advanced features to enhance your observing and imaging experience:

• Dual-Encoder Motor System (Freedom-Find™): This patented system allows for manual movement of the mount without losing alignment, providing unparalleled flexibility during observation.
• SynScan™ Hand Controller: A user-friendly interface with a database of over 42,000 celestial objects, enabling automatic GoTo slewing and precise tracking. It also supports computer control via a USB connection.
• Belt-Driven Stepper Motors: Ensures whisper-quiet operation, minimal backlash, smoother tracking, and reduced periodic error, which is crucial for long-exposure astrophotography.
• Built-in PEC Training: For astrophotographers, the SynScan hand controller includes a feature to train out periodic error, leading to more accurate guiding and pinpoint stars in images.
• DSLR Interface (SNAP Port): Equipped with a DSLR interface and an intervalometer timer, allowing for automated camera control and exposure sequencing for astrophotography. It can control two cameras simultaneously.
• Pier Extension: A sturdy pier extension elevates the mount head, providing ample clearance for the counterweight bar and enabling polar alignment at virtually any latitude.
• Payload Capacity: Designed to handle a payload capacity of up to 30 pounds, accommodating a wide range of optical tubes.

4. Setup

Follow these steps to assemble and prepare your AZ-EQ5 mount for use:

1. Tripod Assembly:

   Unfold the pier tripod legs and secure them. Ensure the tripod is placed on a stable, level surface. The pier extension provides necessary clearance for polar alignment.
2. Mount Head Attachment:

   Carefully attach the mount head to the pier tripod. Secure it firmly using the provided locking mechanisms.

3. Counterweight Installation:

   Slide the counterweights onto the counterweight shaft. If needed, use the counterweight bar extension. Position the counterweights to balance your optical tube assembly (OTA).

6. Power Connection:

   Connect the power cable to the mount and a suitable 12V power source.

7. Polar Alignment:

   For accurate tracking in Equatorial mode, perform polar alignment using the included polar finderscope. The pier extension facilitates alignment at various latitudes. For Alt-Az mode, precise leveling is important.
8. DSLR Camera Connection (Optional):

   If using a DSLR for astrophotography, connect it to the mount's SNAP port using the appropriate trigger cable. The mount supports two cameras simultaneously.

5. Operating Instructions

Operating the Sky-Watcher AZ-EQ5 mount is intuitive with the SynScan hand controller.

5.1. SynScan Hand Controller Operation

• Power On: Turn on the mount. The hand controller will display the initial setup menu.
• Date, Time, and Location: Enter the correct date, time, and your geographical coordinates. This information is crucial for accurate GoTo functionality.
• Alignment Procedure: Select your desired alignment method (e.g., 1-star, 2-star, 3-star alignment for EQ mode, or Brightest Star/Two-Star Alignment for Alt-Az mode). Follow the on-screen prompts to center the alignment stars.
• Object Selection and GoTo: Navigate through the extensive 42,000+ object database using the arrow keys. Once an object is selected, press ENTER to initiate the GoTo function. The mount will automatically slew to the target.
• Tracking: After a successful GoTo, the mount will automatically begin tracking the object to keep it centered in your eyepiece or camera field of view.
• Freedom-Find™ Manual Movement: You can manually move the telescope by hand without losing the mount's alignment. The dual encoders will keep track of the mount's position. After manual movement, the mount will resume tracking.

5.2. Astrophotography Features

• PEC Training: To minimize periodic error for long-exposure astrophotography, access the PEC training function in the SynScan menu. Follow the instructions to record and apply the PEC correction.
• DSLR Camera Control: Use the SNAP port and the SynScan hand controller's built-in intervalometer to program exposure length, number of exposures, and delay times. The controller can trigger your DSLR camera automatically. Up to 8 different exposure combinations can be set.

5.3. Computer Control

The AZ-EQ5 mount features a built-in USB port for computer control. This allows you to control the mount using popular astronomy software such as SkyX, Stellarium, and Starry Nights. You may need to install appropriate ASCOM drivers and specific software versions (e.g., Stellarium Qt5 for ASCOM compatibility).

6. Maintenance

Proper maintenance ensures the longevity and optimal performance of your Sky-Watcher AZ-EQ5 mount.

• Cleaning: Keep the mount clean and free from dust and debris. Use a soft, dry cloth for cleaning. Avoid using harsh chemicals or abrasive materials.
• Storage: When not in use, store the mount in a dry, dust-free environment. It is recommended to disassemble the mount into its main components for long-term storage or transport.
• Cable Management: Ensure all cables are neatly routed and not under tension to prevent damage.
• Firmware Updates: Periodically check the Sky-Watcher website for firmware updates for your SynScan hand controller. Updates can improve performance and add new features. The mount has a built-in USB port for firmware updates.
• Mechanical Checks: Occasionally inspect all mechanical connections and fasteners to ensure they are secure. While the mount is designed for smooth operation, if you experience any unusual stiffness or binding in the axes, it is advisable to consult the manufacturer's support.

7. Troubleshooting

This section addresses common issues you might encounter with your AZ-EQ5 mount.

• Mount Not Responding / Motors Not Moving:
  • Ensure all power and control cables are securely connected.
  • Verify the power supply is providing the correct voltage (12V) and sufficient current.
  • Check the hand controller display for any error messages.
• Inaccurate GoTo / Tracking Issues:
  • Confirm that the correct date, time, and location (latitude/longitude) are entered into the hand controller.
  • Re-perform the alignment procedure with care, ensuring alignment stars are accurately centered.
  • For Equatorial mode, verify precise polar alignment using the polar finderscope.
  • For Alt-Az mode, ensure the tripod and mount head are perfectly level. The mount's built-in bubble level should be cross-referenced with an external level for maximum accuracy.
  • Ensure the mount is properly balanced with your optical tube assembly and counterweights.
• Computer Control Disconnects / Software Issues:
  • Ensure the correct ASCOM drivers for Sky-Watcher mounts are installed on your computer.
  • Verify that your astronomy software is compatible and correctly configured to communicate with the mount (e.g., using the appropriate COM port).
  • Some software, like Stellarium, may require specific versions (e.g., Qt5) for ASCOM compatibility.
  • Check the USB connection cable for damage or loose connections.
• Mechanical Stiffness / Jerky Movement:
  • While the belt-driven system minimizes backlash, if you experience persistent stiffness or jerky motion, ensure no components are overtightened.
  • If the issue persists, it is recommended to contact Sky-Watcher customer support for further assistance.
