Sky-Watcher DOB GOTO8 WiFi Dobsonian Telescope User Manual

Introduction

The Sky-Watcher DOB GOTO8 WiFi Dobsonian Telescope is designed for precise observation of celestial objects with its automatic guidance system. This model features a retractable optical tube, allowing for compact transportation of its large 20cm Newtonian reflector. The included hand controller is equipped with Japanese firmware and button labels for ease of use. With standard WiFi connectivity, the telescope can also be operated via a dedicated smartphone or tablet application.

Setup and Assembly

Before first use, carefully assemble your Sky-Watcher Dobsonian Telescope following these steps. Ensure all components are present and undamaged.

1. Unpack Components: Carefully remove all parts from the packaging. Verify against the packing list that all components, including the optical tube, Dobsonian base, hand controller, and accessories (finder scope, eyepieces), are present.
2. Assemble the Dobsonian Base: Follow the instructions provided in the separate base assembly guide (if applicable) to construct the Dobsonian mount. Ensure all screws are tightened securely.
3. Attach the Optical Tube: Gently place the optical tube onto the Dobsonian base. Secure it using the provided clamps or mounting screws. Ensure the tube is balanced and stable.
4. Install Finder Scope: Attach the 8x50 finder scope to its designated bracket on the optical tube. Align it with the main telescope later during initial setup.
5. Connect Hand Controller: Plug the hand controller cable into the appropriate port on the telescope mount. Ensure a secure connection.
6. Power Connection: Connect the telescope to a suitable power source (e.g., 12V DC power supply, not included).

For detailed visual instructions, refer to the assembly diagrams in the quick start guide.

Operating Instructions

This section details the operation of your Sky-Watcher DOB GOTO8 WiFi Dobsonian Telescope, including initial alignment and using the GOTO and WiFi features.

Initial Alignment (Star Alignment)

1. Power On: Turn on the telescope. The hand controller display will illuminate.
2. Enter Date and Time: Follow the on-screen prompts to enter the current date, time, and your location coordinates. Accuracy is crucial for precise GOTO functionality.
3. Select Alignment Method: Choose a star alignment method (e.g., 2-star alignment) from the hand controller menu.
4. Point to Alignment Stars: The hand controller will prompt you to point the telescope at specific bright stars. Use the directional buttons to center each star in your eyepiece. Confirm each star once centered.
5. Alignment Complete: Once alignment is successful, the telescope is ready for GOTO operations.

Using GOTO Functionality

After successful alignment, you can use the GOTO feature to automatically locate celestial objects.

• Browse Catalog: Navigate through the hand controller's menu to select an object from the built-in celestial catalog (e.g., planets, nebulae, galaxies).
• Initiate GOTO: Press the GOTO button. The telescope will automatically slew to the selected object's coordinates.
• Fine Adjustment: Once the telescope stops, make minor adjustments using the directional buttons to center the object perfectly in your eyepiece.

WiFi Control via Smartphone/Tablet

The DOB GOTO8 features integrated WiFi, allowing control via a dedicated mobile application.

1. Download App: Download the official Sky-Watcher SynScan Pro app (or equivalent) from your device's app store.
2. Connect to Telescope WiFi: On your smartphone/tablet, connect to the WiFi network broadcast by the telescope (usually named "SynScan_WiFi" followed by numbers).
3. Launch App: Open the SynScan Pro app. It should automatically detect and connect to the telescope.
4. Control Telescope: Use the app's interface to perform alignment, browse celestial objects, and control the telescope's movement.

Maintenance

Proper maintenance ensures the longevity and optimal performance of your telescope.

• Optical Tube Cleaning:
  • Mirrors: Avoid touching the primary and secondary mirrors. If cleaning is necessary, use a specialized optical cleaning kit and follow instructions carefully. Dust can often be removed with a blower brush.
  • Eyepieces: Clean eyepieces with a soft, lint-free cloth and optical cleaning solution.
• Mechanical Parts: Keep the Dobsonian base and moving parts free from dust and debris. Periodically check and tighten any loose screws. Do not lubricate gears unless specifically instructed by Sky-Watcher.
• Storage: Store the telescope in a dry, dust-free environment. Use dust caps for the optical tube and eyepieces when not in use. If storing for extended periods, consider disassembling the optical tube from the base and storing them in their original packaging or protective cases.
