  • Baader ClickLock Eyepiece Clamp - 1.25"/T-2

    The Baader ClickLock Eyepiece Clamp replaces insecure thumbscrews with a professional-grade clamping mechanism for your 1.25-inch accessories. This T-2 compatible clamp uses a cam-lever system, inspired by CNC machine tool holders, to secure any 1.25-inch eyepiece or camera with a gentle twist of its outer ring.

    The ClickLock Mechanism: Secure Clamping Without Screws

    Forget fumbling with tiny screws in the dark, especially with gloves on. The ClickLock system grabs your 1.25-inch accessories with a short, gentle twist, applying even, concentric pressure. This three-point grip centers the accessory perfectly on the optical axis, eliminates tilting, and prevents the scratches and gouges that single thumbscrews leave on your eyepiece barrels.

    The internal leverage multiplies your gripping force, ensuring even heavy CCD cameras or eyepiece stacks are held rigidly without requiring excessive torque. The result is a connection that is stable, repeatable, and safe for your most valued equipment.

    T-2 System Integration for Imagers and Visual Observers

    This clamp is a core component of the Baader T-2 Astro-System. The telescope side features a standard T-2 (M42x0.75) female thread, allowing you to connect it directly to T-2 diagonals, extension tubes, and other accessories for a rigid, threaded connection that bypasses traditional slip-fit focusers.

    Unscrewing the ClickLock's top ring reveals a male T-2 thread on the eyepiece side. This transforms the clamp into an eyepiece projection adapter, enabling you to securely mount T-rings and DSLR or mirrorless cameras for high-magnification planetary and lunar imaging.

    Integrated Helical Focuser: Precision Adjustments Without Mirror Shift

    A key feature of the ClickLock T-2 clamp is its integrated fine-focusing mechanism. The body of the clamp acts as a micro-focuser with a fine-pitch thread, allowing you to make delicate focus adjustments right at the eyepiece. This is a critical upgrade for Schmidt-Cassegrain (SCT) owners, as it allows you to bypass the telescope's primary mirror focuser for final tweaks, completely eliminating mirror shift and image rock.

  • How does the Baader ClickLock 1.25"/T-2 clamp work without screws?

    The Baader ClickLock clamp uses an internal cam and lever system. When you twist the outer ring, three hardened steel pins move inward to grip the eyepiece barrel concentrically. This provides a secure, self-centering grip that is much more stable than a single thumbscrew and will not mar your accessories.

    Will the Baader ClickLock T-2 clamp securely hold a heavy camera for astrophotography?

    Yes. The mechanical design multiplies the force you apply, creating a very strong grip with only a light twist. It is engineered to securely hold heavy 1.25-inch format CCD or CMOS cameras and accessory stacks without slipping or tilting, providing a much more rigid connection than standard clamps.

    Can I use the Baader ClickLock 1.25"/T-2 clamp to fix mirror shift on my Celestron 8" SCT?

    Absolutely. This is one of its primary applications. After achieving rough focus with your SCT's main knob, you can use the integrated helical focusing mechanism on the ClickLock clamp for fine, final adjustments. This moves the eyepiece, not the primary mirror, eliminating mirror shift for critical planetary imaging and high-power visual observation.

    What are the thread types on the Baader ClickLock T-2 clamp?

    The Baader ClickLock T-2 clamp has two primary threads:

    • Telescope Side: A female T-2 (M42x0.75) thread for connecting to T-2 diagonals, focusers, or other system components.
    • Eyepiece Side: A male T-2 (M42x0.75) thread is hidden underneath the twist-lock ring, allowing you to use it for eyepiece projection with T-rings and cameras.

    How does the fine-focus feature on the Baader ClickLock clamp help when imaging Jupiter?

    When imaging Jupiter at high magnification, achieving perfect focus is critical and often compromised by mirror shift. The Baader ClickLock allows you to lock the primary mirror and then use the clamp's own fine-focusing thread to nail the focus without causing the planet to jump around in the field of view. This stability is essential for capturing sharp, detailed images.

    Can I use the Baader ClickLock clamp for eyepiece projection photography?

    Yes. By unscrewing the outer locking ring, you expose a male T-2 thread. You can place a 1.25" eyepiece inside the clamp, and then attach a T-2 extension tube and a camera-specific T-ring to this thread. This creates a secure, variable-projection system for high-magnification imaging.
