The William Optics WO x0.72 Reducer Flattener 8 is a high-performance optical accessory designed to enhance the capabilities of William Optics refractor telescopes. This dual-function device acts as both a focal reducer and a field flattener, significantly improving image quality and versatility for astrophotography.
Specifically designed for use with William Optics refractor telescopes. Ensure compatibility with your specific telescope model before purchase.
Compatibility
Engineered to work seamlessly with William Optics refractor telescopes, particularly those with focal ratios around f/8. It's crucial to verify compatibility with your specific telescope model to ensure optimal performance and proper spacing.
Optical Performance
Provides a 0.72x reduction factor, effectively shortening the telescope's focal length while maintaining excellent image quality. Simultaneously corrects for field curvature, ensuring sharp, well-defined stars across the entire field of view.
Focal Reduction:
By reducing the focal length by a factor of 0.72x, this device increases the telescope's field of view and decreases the effective f-ratio. This allows for shorter exposure times, wider sky coverage, and improved light gathering, benefiting both deep-sky astrophotography and widefield imaging.
Field Flattening
Effectively 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 feature is particularly valuable for astrophotographers using large sensors or pursuing widefield celestial imagery.
Construction
Crafted with high-quality optical glass and precision-engineered components to maintain the stellar image quality William Optics telescopes are renowned for. The body is likely constructed from durable materials such as anodized aluminum, ensuring longevity, thermal stability, and minimal flexure.
Ease of Use
Features industry-standard threaded connections for straightforward attachment to both the telescope and camera. The compact and lightweight design integrates seamlessly into the imaging train without adding significant back focus or weight, maintaining balance and portability.
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, star clusters, or expansive nebulae. Its 0.72x reduction factor offers a good balance between field widening and maintaining sufficient magnification for detailed observation.
