More information

  • The William Optics x0.8 Reducer Flattener 7A is a specialized optical accessory designed to enhance the performance of William Optics refractor telescopes. This dual-purpose device serves as both a focal reducer and a field flattener, improving image quality and expanding the telescope's capabilities for astrophotography.

    Disclaimer

    Specifically designed for use with William Optics refractor telescopes. Check compatibility with your specific model before purchasing.

    Compatibility

    Designed to work seamlessly with William Optics refractor telescopes, particularly those with focal ratios around f/7. It's essential to verify compatibility with your specific telescope model to ensure optimal performance.

    Optical Performance

    William Optics x0.8 Reducer Flattener 7A side view

    Offers a 0.8x reduction factor, shortening the telescope's focal length while maintaining image quality. Simultaneously corrects for field curvature, ensuring sharp stars across the entire field of view.

    Focal Reduction:

    By reducing the focal length by a factor of 0.8x, this device increases the telescope's field of view and decreases the effective f-ratio. This allows for shorter exposure times and wider sky coverage, beneficial for both deep-sky astrophotography and widefield imaging.

    Field Flattening

    Corrects for field curvature inherent in many refractor designs, ensuring that stars remain pinpoint sharp from the center to the edges of the frame. This is particularly valuable for astrophotographers using large sensors or shooting widefield images.

    Construction

    Built with high-quality optical glass and precision-engineered components to maintain the excellent image quality William Optics telescopes are known for. The body is likely constructed from durable materials such as anodized aluminum for longevity and thermal stability.

    Ease of Use

    Features a standard threaded connection for easy attachment to the telescope and camera. The compact design integrates seamlessly into the imaging train without adding significant back focus or weight.

    Versatility

    While primarily designed for astrophotography, this reducer/flattener can also benefit visual observers by providing a wider true field of view, especially useful for observing large deep-sky objects or star fields.
