  • PrimaLuceLab HEQ5, Sirius EQ-G PLUS Adapter Plate

    The PrimaLuceLab HEQ5, Sirius EQ-G PLUS Adapter Plate is a fundamental upgrade that replaces the stock Vixen-only saddle on your mount, adding the crucial ability to use wider, more stable Losmandy-style dovetail bars. This single component unlocks the full potential of your mount, allowing you to securely attach larger telescopes and heavy imaging rigs that require the Losmandy standard for a flex-free connection.

    Dual Vixen & Losmandy Saddle: Upgrade Your HEQ5 or Sirius Mount

    The Sky-Watcher HEQ5 and Orion Sirius EQ-G are excellent mid-range mounts, but their native Vixen-style saddle is a limiting factor for serious astrophotography. Larger optical tubes, especially refractors and Schmidt-Cassegrains used for deep-sky imaging, rely on the wider Losmandy "D-style" plate for superior stability. This PLUS adapter plate directly replaces the original saddle, instantly providing dual compatibility without compromising the ability to use your existing Vixen plates.

    The PLUS System Advantage: Integration Beyond a Simple Adapter

    While other adapters provide dual-saddle functionality, the PrimaLuceLab PLUS plate integrates your mount into a complete ecosystem of rings, plates, and accessories. Machined from high-quality aluminum and finished in signature red anodizing, it ensures a perfect, non-flexing fit with other PLUS components. This system-level approach eliminates the weak points in your imaging train, creating a mechanically seamless connection from the mount head to the telescope tube.

    • Robust Clamping: Large, easy-to-grip knobs provide a secure lock on your dovetail bar, preventing slips or shifts during a long imaging session.
    • Precision Machining: The adapter is engineered for a perfect fit on the HEQ5/Sirius mount head, ensuring proper alignment and load distribution.
    • Ecosystem-Ready: Use this adapter as the foundation for building a complete, rigid imaging platform with PLUS guide rings, side-by-side plates, and other accessories.

  • What is the main benefit of installing the PrimaLuceLab PLUS Adapter Plate on my HEQ5 mount?

    The primary benefit is adding Losmandy-style dovetail compatibility. The stock HEQ5 mount only accepts narrower Vixen-style bars. This adapter allows you to use both Vixen and the more rigid, wider Losmandy bars, which are standard on many larger telescopes used for astrophotography.

    Is this adapter plate compatible with the Orion Sirius EQ-G mount?

    Yes. The Orion Sirius EQ-G and the Sky-Watcher HEQ5 mounts share the same mechanical design for the head, so the PrimaLuceLab PLUS Adapter Plate is fully compatible with both models.

    Will I still be able to use my telescopes with Vixen-style dovetails with this adapter?

    Absolutely. The adapter is a dual-saddle design. It has a clamping system that securely holds both Losmandy "D-style" plates and Vixen "V-style" plates, so you retain full compatibility with all of your existing equipment.

    What makes the PrimaLuceLab PLUS adapter different from other dual saddles?

    The key difference is its integration into the PrimaLuceLab PLUS ecosystem. While other adapters work as standalone parts, the PLUS adapter is designed to connect seamlessly with a wide range of other PLUS components, such as guide rings and mounting plates, ensuring a consistently rigid and flex-free system from the mount up.

    I want to mount my 8" SCT with a Losmandy bar on my Sirius mount for imaging galaxies like the Whirlpool Galaxy (M51). Is this the right part?

    Yes, this is exactly the part you need. An 8" SCT is often supplied with a Losmandy-style bar for better stability, which the stock Sirius mount cannot accept. By installing this adapter, you can securely mount your SCT and achieve the rigidity needed for long-exposure imaging of targets like M51.

    How does this PrimaLuceLab adapter help with balancing a guidescope alongside my main refractor on an HEQ5?

    This adapter serves as a solid foundation. You can attach a long Losmandy-style bar to your main refractor, mount it in this saddle, and then use PLUS guide rings attached to that same bar to hold your guidescope. The wide, secure grip of the saddle on the Losmandy bar prevents flex and makes it easier to achieve precise balance in both axes.
