More information

  • The Askar 3" F/3.9 Full Frame Reducer is a specialized optical accessory designed to enhance the imaging capabilities of the Askar FRA600 telescope. This focal reducer decreases the telescope's focal ratio to f/3.9, allowing for faster exposures and a wider field of view while maintaining excellent image quality across full-frame sensors.

    Disclaimer

    Specifically designed for use with the Askar FRA600 telescope. Ensure compatibility with your camera sensor size before purchase.

    Optical Performance


    The 3" F/3.9 Full Frame Reducer features high-quality optics designed to maintain sharp, well-corrected images across the entire field of view, even with full-frame sensors. It effectively reduces the focal length of the FRA600 telescope while minimizing optical aberrations, ensuring excellent image quality for astrophotography.

    By reducing the focal ratio to f/3.9, this reducer allows for significantly faster exposures, making it easier to capture faint deep-sky objects. The wider field of view also enables imaging of larger celestial targets, expanding the range of objects that can be photographed with the FRA600 telescope.

    Full-Frame Optimization


    Specifically designed to cover full-frame sensors, this reducer ensures edge-to-edge sharpness and minimal vignetting across the entire image field. This makes it an ideal choice for astrophotographers using full-frame DSLR or mirrorless cameras, as well as large-format astronomical CCD cameras.

    Construction Quality


    Built with high-quality materials and precision-engineered optics, the reducer is designed to withstand the rigors of frequent use and maintain its optical alignment. The robust construction ensures consistent performance over time, making it a reliable addition to your astrophotography kit.

    Easy Integration


    The 3" format ensures easy integration with the Askar FRA600 telescope and compatibility with standard astronomy equipment. The reducer is designed for straightforward installation and removal, allowing for flexible use based on your imaging needs.

    Versatility


    While optimized for full-frame sensors, this reducer can also be used with smaller sensor sizes, offering even wider fields of view. This versatility makes it suitable for a range of astrophotography projects, from wide-field Milky Way shots to detailed images of large nebulae and galaxies.
