    ZWO FF107 APO - Overview

    The ZWO FF107-APO is a high-performance refractive astrograph designed for both imaging and visual observation. With its quadruplet air-spaced APO optical design, the FF107-APO offers sharp, high-contrast images with minimal chromatic aberration, making it an excellent choice for astrophotographers and stargazers alike.

    Quadruplet APO Optical Design

    Equipped with two ED glasses, this design provides superior control over chromatic and other optical aberrations.

    Delivers small, round stars with a central RMS radius of 3 microns, ensuring excellent imaging clarity.

    No Field Flattener Needed

    Self-flattening design eliminates the need for a separate flattener, simplifying the setup and reducing the cost of accessories.

    Just connect your accessories, focus the target, and the system will be ready for imaging.

    Full-Frame Imaging Support

    The 44mm image circle is perfect for full-frame cameras, such as the AS16200, providing a wide field of view and preserving sharp stars across the entire frame.

    Compact and Lightweight Design

    With a total weight of 6.9kg (including accessories), this telescope is both portable and robust.

    Its 107mm aperture and 749mm focal length make it a versatile tool for various astrophotography setups.

    3.4" Dual-Speed Focuser

    Features a 3.4" rack and pinion focuser with 1:10 fine adjustment for precise focusing.

    Includes a 360-degree rotator for easy framing of your imaging targets.

    Versatile Adapters Included

    Comes with M48, M54, M68, and M86 adapters for seamless attachment of cameras and accessories.

    The M48 adapter includes a 2" filter thread, allowing you to easily add filters to your setup.

    Connection to Camera or Accessories

    1. Choose the appropriate M48, M54, M68, or M86 adapter based on your equipment.
    2. Secure the adapter to the focuser and attach your camera or accessory.

    Using the 3.4" Focuser

    1. Adjust the fine focus using the 1:10 dual-speed knob for precise focusing.
    2. For coarse adjustments, use the larger focusing knob for faster movement.

    Installing and Removing the Lens Hood

    1. Attach the telescopic lens hood to the front of the telescope.
    2. Secure it with the thumb screws to ensure it stays in place during use.

    Note

    The ZWO FF107-APO is perfect for both imaging and visual observation, offering exceptional quality for planetary views as well as deep sky astrophotography.

    It’s designed for users who want a high-performance, easy-to-use telescope with minimal setup complexity.
