  • Antlia 3x Barlow Lens for 5Å CaK Solar Filter

    The Antlia 3x Barlow Lens is engineered as a dedicated optical amplifier for the Antlia Solar Discover 5Å CaK filter assembly. It triples the effective focal length of your telescope, enlarging the solar image to show finer details in the sun's chromosphere. Antlia says it enhances detail when used, optimizing performance for solar photography, and offers optional 50mm and 70mm extension tubes for more back focus if needed.

    3X Magnification for High-Resolution CaK Imaging

    This Barlow provides a fixed 3X magnification for imaging within the narrow 5Å Calcium-K line. By increasing the image scale, you can better sample small features like plages, light bridges and sunspots, filling more of your camera sensor with the solar surface.

    Antlia designed it specifically for the Antlia 5Å CaK assembly. Antlia publishes no optical prescription or contrast data for the Barlow.

    Achieving Focus with Optional 50mm and 70mm Extension Tubes

    Introducing a Barlow into an optical train can require more back focus. Antlia offers optional 50mm and 70mm extension tubes, ordered separately, to achieve more back focus if needed when using the 5Å CaK assembly with a Barlow lens. This supports the solar imaging system in achieving co-focus during shooting.

    • System-Specific Solution: Antlia provides the extension tubes for use with the 5Å CaK assembly and a Barlow lens.
    • Purchase Options: You can acquire the Antlia 3x Barlow separately to upgrade an existing 5Å CaK filter or order the assembly with it pre-installed.

  • What is the primary purpose of the Antlia 3x Barlow Lens?

    The Antlia 3x Barlow Lens is designed to triple the magnification when used with the Antlia Solar Discover 5Å CaK filter assembly. Antlia says it enhances detail when used, optimizing performance for solar photography of features such as plages, light bridges and sunspots.

    When would I need the optional 50mm or 70mm extension tubes with the Antlia 3x Barlow?

    You need one of the optional extension tubes if your setup lacks back focus with the Barlow fitted; Antlia offers them for more back focus 'if needed'. Adding the Barlow changes the optical path length, pushing the focal point further out. The 50mm and 70mm extension tubes provide the necessary spacing to allow your camera to reach this new focus position.

    Can I use the Antlia 3x Barlow with other solar filters or for nighttime observing?

    Antlia designs this Barlow specifically for the Antlia Solar Discover 5Å CaK assembly and states no other use, so we do not recommend it with other solar filters or for nighttime observing.

    How does the Antlia 3x Barlow help when imaging with a short focal length refractor?

    A short focal length refractor produces a small solar image. The Antlia 3x Barlow increases the effective focal length by a factor of three, making the image much larger on your camera sensor, so small features such as plages and light bridges cover more pixels. Without extra light reduction, Antlia limits the 5Å CaK assembly to refractors up to 100mm aperture.

    Should I order the Antlia 3x Barlow pre-installed or separately?

    Ordering the Barlow pre-installed with the Antlia 5Å CaK Assembly means it comes already installed in the assembly. Ordering it separately is the choice if you already own the CaK filter and wish to upgrade your system for higher-magnification solar imaging.

    Will adding the Antlia 3x Barlow reduce the contrast of the 5Å CaK filter?

    Antlia says its Barlow, designed specifically for the 5Å CaK assembly, enhances detail when used, optimizing performance for solar photography. Antlia gives no contrast figures for the Barlow itself.
