商品描述

    1. Compatibility Check: Ensure that the collimating ring is compatible with your specific telescope model. In this case, check if your telescope is one of the models (RC6, CC6, RC8, or CC8) listed as compatible with the GSO FF670.

    2. Installation: Insert the collimating ring between the rear cell of your telescope and the focuser. Ensure that it is securely in place.

    3. Adjustment: Since the collimating ring is spring-loaded, you can make adjustments to the tilt angle of the focuser easily. This is particularly useful for optimizing the alignment of your optical system, ensuring that images remain sharp across the entire field of view.

    4. Back Focus Considerations: Take note of the 15mm back focus requirement. Ensure that the collimating ring doesn't interfere with the overall back focus distance needed for your imaging setup.

    5. Imaging Sessions: During imaging sessions, you can make real-time adjustments to the tilt angle of the focuser using the collimating ring, allowing you to achieve optimal image quality.
