    Omegon Apochromatic Refractor Pro APO AP 121/678 Quintuplet OTA

    The Omegon Apochromatic Refractor OTA is designed to meet the high standards of astrophotography enthusiasts. Offering superior optical performance and precision, this apochromat triumphs in its ability to capture the night sky with unparalleled clarity.

    Optical Excellence for Astrophotography

    This quintuplet refractor, with a 121mm aperture and five-lens configuration, utilizes premium ED glass for astrophotography that showcases sharp detail and vibrant colors. By incorporating an integrated flattener, it wards off image distortion across the entire field, especially beneficial for users with full-frame cameras.

    Attention to Detail

    • Quintuplet ED-Apo, featuring five lenses to achieve exquisite astrophotos with optimal color correction.
    • The integrated two-lens corrector fully illuminates the camera sensor, fitting an image circle diameter of 49mm.
    • The 4" focuser, designed for heavy-duty use, allows for precise focusing with a 1:10 reduction ratio, ensuring that heavier cameras are easily accommodated without compromising on precision.
    • Camera rotation capability at 360° enables photographers to adjust orientation swiftly, making it hassle-free to frame the desired celestial object.
    • An 82mm thread ensures a robust and secure connection between your telescope and additional accessories.
    • Includes an M48x0.75 camera adapter.

    Why Opt for Omegon Optics?

    With this apochromat, detail and contrast are significantly enhanced, making celestial observations and astrophotography more rewarding. Planets and distant galaxies appear with sharp outlines and high contrast, thanks to the meticulously crafted optics and multi-coated lens surfaces.

    Focuser Mechanics

    The focuser's large size suits full-frame enthusiasts, providing expansive space for excellent illumination and image capture without vignetting. A combination of Crayford and gear technology grants smooth focusing even under the weight of substantial equipment. Fine adjustments are made effortless with a 1:10 geared reduction.

    Solid and Reliable Construction

    The telescope tube is constructed using CNC machining, equipped with an advanced anti-reflective system and lined with velvet-like black fabric to absorb stray light effectively. This provides an enhanced visual experience free from unwanted reflections.

    Additional Features for Convenience

    • The dew cap can be extended to prevent lens fogging and retracted for easy transport; it is adjustable and secures with a simple screw.
    • The integrated mounting thread allows for the firm attachment of essential astrophotography accessories, ensuring nothing shifts out of place during observation.

    Designed for both novice and experienced astronomers, the Omegon Apochromatic Refractor positions itself as an indispensable tool for those passionate about exploring and photographing the cosmos.
