4. Operating Instructions

Once the T-adapter and camera are securely attached to your telescope, you are ready to begin astrophotography.

1. Camera Settings: Set your camera to manual focus and manual exposure mode. The T-adapter does not support autofocus or automatic aperture control.
2. Focusing: Use your telescope's focuser knobs to achieve sharp focus. It may require fine adjustments to get a clear image on your camera's live view or through test shots.
3. Exposure: Experiment with different ISO settings, shutter speeds, and white balance to capture the desired image. Longer exposures are often required for faint celestial objects.
4. Filters: If using 1.25" astronomy filters, thread them into the barrel of the T-adapter before inserting it into the focuser.

5. Maintenance

Proper care and maintenance will extend the life and performance of your T-adapter.

• Cleaning: Use a soft, lint-free cloth to wipe the exterior of the adapter. Avoid using harsh chemicals or abrasive materials.
• Storage: Store the T-adapter in a clean, dry place, preferably in its original packaging or a protective case, when not in use.
• Thread Care: Keep the threads clean and free of debris to ensure smooth attachment and removal.

6. Troubleshooting

If you encounter issues, consider the following common solutions:

• Cannot achieve focus: Ensure your camera is set to manual focus. Adjust the telescope's focuser slowly and carefully. Some telescopes may require an additional extension tube for optimal focus with certain camera setups.
• Loose connection: Double-check that both the T-mount is securely attached to the camera and the T-adapter is firmly seated in the telescope's focuser with the thumbscrews tightened.
• Image quality issues (dark corners, vignetting): This can sometimes occur due to the sensor size of your camera relative to the telescope's light path. Ensure all connections are clean and free of obstructions.
• Camera not recognizing adapter: The T-adapter is a mechanical connection and does not transmit electronic signals. Your camera should be operated in manual mode.
