  • 2X Barlow 1.25inch with M42 Threads

    This 2X Barlow lens instantly doubles the power of any 1.25" eyepiece and features an integrated M42x0.75 thread for direct camera attachment. Constructed from solid metal with a compact 7.5cm length, its pure optical glass lenses are treated with a multilayer HD broadband green film to maximize image contrast and light transmission.

    2X Magnification with Multilayer HD Coatings

    By doubling the magnification of your eyepiece collection, this 2X Barlow brings fine details on Jupiter's cloud bands and the Moon's craters into sharp focus. The pure optical glass lenses feature a multilayer HD broadband green film, ensuring the magnified view remains bright and high-contrast by mitigating the inherent light loss of adding extra glass elements.

    • Double Your Eyepiece Collection: Effectively turns your existing eyepieces into a set with twice the magnification options, ideal for achieving the optimal power for planetary viewing.
    • High-Contrast Views: The multilayer HD green film preserves the original image quality by minimizing internal reflections, which is critical for discerning subtle planetary features.

    M42 x 0.75 Threads for Direct Camera Attachment

    The integrated M42x0.75 thread transforms this Barlow from a visual accessory into an imaging tool. This standard T-thread allows you to securely connect a DSLR or dedicated astronomy camera (with the appropriate T-ring, not included) directly to the Barlow, creating a solid optical train for high-magnification lunar and planetary astrophotography.

    All-Metal Construction in a 2.95-inch Body

    Built entirely from metal, this Barlow is designed for rigidity and long-term use in the field. At a length of just 2.95 inches (7.5cm), it adds minimal length to your imaging train and balances easily, while providing a secure, non-flexing platform for both heavy eyepieces and cameras.

  • How does this 2X Barlow lens affect my telescope's focal length?

    This 2X Barlow doubles your telescope's effective focal length. For example, if you have a telescope with a 1000mm focal length, using this Barlow makes it perform like a 2000mm telescope, doubling the magnification of any eyepiece you use with it.

    What do I need to connect my camera to the Barlow's M42 threads?

    You will need a T-ring that is specific to your camera's lens mount (e.g., Canon EOS, Nikon F, Sony E-mount). The T-ring screws onto the Barlow's M42x0.75 threads, and your camera body then attaches to the T-ring as it would to a lens.

    Will this 1.25-inch Barlow work with 2-inch eyepieces?

    No. This Barlow has a 1.25" barrel and is designed to be used with standard 1.25" eyepieces and accessories only. It will not fit into a 2" focuser without an adapter, and it cannot hold a 2" eyepiece.

    Is this 2X Barlow suitable for deep-sky objects?

    While primarily designed for high-magnification views of bright objects like the Moon and planets, it can be used to get a closer look at smaller, bright deep-sky objects like planetary nebulae (e.g., the Ring Nebula, M57) or globular clusters (e.g., the Hercules Cluster, M13). However, it will dim the view, which is not ideal for faint galaxies or large nebulae.

    How will this 2X Barlow perform on Saturn with an 8-inch f/10 SCT?

    An 8" f/10 SCT has a focal length of around 2000mm. This 2X Barlow will increase that to 4000mm. With a 20mm eyepiece, this would yield 200x magnification, an excellent power for seeing Cassini's Division in Saturn's rings and subtle cloud bands on the planet's surface under steady seeing conditions.

    Can I use this 2X Barlow to get a closer view of the Orion Nebula (M42) in my 4-inch refractor?

    Yes, you can use it to magnify specific regions within the Orion Nebula (M42), such as the Trapezium star cluster at its core. However, the 2X magnification will also darken the image and significantly narrow the field of view, preventing you from seeing the entire nebula at once. For wide, bright views of M42, it's best to observe without a Barlow.
