This allows you to standardize your eyepiece holders across different instruments for a consistent, reliable user experience.\u003c\/p\u003e\n\u003cp\u003eThe system includes direct-thread adapters for focusers from Astro-Physics, Takahashi, Feather Touch (2.5\", 3.0\", and 3.5\"), Vixen, Zeiss, and Explore Scientific. Specific models are available for the common 2\" and 3.3\" SCT threads found on Celestron and Meade telescopes, as well as M56 and S57 ring-dovetails for Sky-Watcher and Celestron Newtonians, and the universal M42x0.75 T-2 thread for custom imaging trains.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eClickLock vs. Thumbscrews: Eliminating Tilt with 2-Inch Accessories\u003c\/h3\u003e\n\u003cp\u003eA standard thumbscrew holder is the weakest link in most optical trains. By applying pressure from a single point, it inherently pushes the eyepiece or camera barrel off-axis, introducing tilt. This misalignment degrades optical corrections, harms edge-of-field sharpness, and can make precise collimation impossible. For imaging, this tilt is a primary cause of elongated stars in the corners of the frame.\u003c\/p\u003e\n\u003cp\u003eThe Baader ClickLock system solves this problem completely. Its concentric clamping action ensures the accessory's barrel is held perfectly parallel to the focuser drawtube.

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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eThe ClickLock Mechanism: Secure Clamping Without Screws\u003c\/h3\u003e\n\u003cp\u003eForget 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eT-2 System Integration for Imagers and Visual Observers\u003c\/h3\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003cp\u003eUnscrewing 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eIntegrated Helical Focuser: Precision Adjustments Without Mirror Shift\u003c\/h3\u003e\n\u003cp\u003eA 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eHow does the Baader ClickLock 1.25\"\/T-2 clamp work without screws?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWill the Baader ClickLock T-2 clamp securely hold a heavy camera for astrophotography?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes. 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eCan I use the Baader ClickLock 1.25\"\/T-2 clamp to fix mirror shift on my Celestron 8\" SCT?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eAbsolutely. This is one of its primary applications.

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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eCan I use the Baader ClickLock clamp for eyepiece projection photography?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes. 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.
