The 0.9x corrector / reducer designed for the Sky-Watcher Evolux-82ED is a top-of-the-range accessory for astrophotographers wishing to exploit the full potential of this apochromatic refractor. Specifically developed to deliver exceptional image quality, it reduces the focal length while greatly enhancing field correction to produce perfectly sharp stars right down to the corners of the image.
Its optical formula is based on a two-element design with integrated ED element, The result is excellent control of chromatic aberrations and precise reproduction of deep-sky details. Thanks to its 0.9x, This corrector reduces the Evolux-82ED's standard focal length to obtain a final focal length of 477 mm with fast opening of f/5.8. This combination increases the photographic field of view while reducing the exposure times required for astrophotography.
This corrector/reducer also offers very high quality field correction, guaranteeing fine, punctual stars across the entire image. It illuminates a full-format sensor and provides excellent optical coverage thanks to a 36 mm image circle. This makes it ideally suited to full-frame SLR and hybrid cameras, as well as modern astrophotography cameras.
With a 4.34° field of view, This accessory makes it possible to capture large areas of the sky, such as large nebulae, open clusters or extensive stellar fields. Its fast f/5.8 focal ratio significantly enhances deep-sky imaging efficiency, especially for faint objects requiring high light collection.
The corrector has a standard 55 mm back focus, This makes it easy to install a wide range of cameras and astrophotographic accessories without complex configuration. It is supplied with a adapter with field rotator, This makes it easy to adjust image framing while maintaining precise focus. This feature greatly enhances user comfort during observation and photography sessions.
The optics benefit from fully multilayer, This treatment optimizes light transmission and effectively reduces internal reflections. This treatment improves image contrast and contributes to more detailed shots with natural colors and a more even sky background.
The adapter also features an internal thread compatible with 2-inch filters, This allows the use of light pollution, narrowband or UV/IR cut filters directly in the optical train. This solution simplifies installation and reduces the number of accessories required.
In terms of connectors, the corrector/gearbox has the following threads M56x1 female and M48 male, This ensures compatibility with a wide range of accessories and adapters on the market. This design guarantees a solid connection perfectly suited to modern astrophotography configurations.
Designed specifically for the Sky-Watcher Evolux-82ED, this corrector/reducer is an ideal solution for astrophotographers looking for a wider field of view, reduced exposure times and impeccable image quality. Its combination of optical speed, excellent field correction and full-format compatibility make it a must-have accessory for deep-sky imaging.
