Optimized for astrophotography, this focal reducer is specially designed for the telescope Sky-Watcher Evostar 150EDX. It transforms your instrument into a faster, larger system, ideal for deep-sky imaging.
Thanks to its 0.77x, It reduces the telescope's focal length while improving overall brightness. This translates into shorter exposure times and greater efficiency during astrophotography sessions. The focal ratio is thus reduced (for example, from f/7 to approx. f/5.4), making the instrument more effective on faint objects such as nebulae and galaxies.
In addition to reducing the focal length, this accessory acts as a field corrector, This improves the sharpness of stars throughout the image. The edges of the field are better corrected, limiting distortion and coma, which is essential for modern APS-C and full-frame sensors.
Its multi-coated optical design ensures excellent light transmission and high contrast. This results in cleaner, more detailed images with improved color rendering.
This accessory is therefore ideal for astrophotographers wishing to optimize their setup without changing telescope, by improving field of view, brightness and overall image quality.
