  • PrimaLuceLab Guide Rings PLUS 115mm

    The PrimaLuceLab Guide Rings PLUS 115mm provide a rock-solid mounting platform for parallel guide scopes. Machined from a single aluminum block for maximum rigidity, these rings are fully integrated into the modular PLUS ecosystem to deliver zero-flexure performance for precise autoguiding.

    Robust Construction: CNC Machining and Hard Anodizing

    Each PLUS 115mm guide ring is CNC-machined from a solid block of aluminum, ensuring high mechanical precision and structural integrity. The surface is sandblasted for a smooth finish and then hard-anodized, a process that significantly increases the material's hardness and protects it from oxidation and scratching, even in harsh field conditions.

    PLUS System Integration: A Foundation for Rigid Guiding

    As a core component of the Prima Luce Universal System (PLUS), these guide rings are designed for maximum rigidity and modularity. They feature threaded holes that allow for a secure two-screw attachment to other PLUS elements like support rings and dovetail clamps, completely eliminating any possibility of rotation that can ruin a long exposure.

    • Native PLUS Connection: Attaches directly to PLUS dovetail plates and support rings for a perfectly stable, integrated guiding system.
    • Cross-Brand Compatibility: A series of central slots allows you to mount the rings on plates or support rings from other brands using a standard screw.
    • Easy Balancing: When mounted on a PLUS dovetail plate, you can slide the rings forward or backward to achieve perfect balance with your guide scope.

  • What is the primary purpose of the PrimaLuceLab PLUS 115mm rings?

    The PLUS 115mm rings are designed to securely mount a guide telescope parallel to your main imaging telescope. Their 115mm internal diameter is suitable for guide scopes such as 80mm class refractors, providing a rigid connection essential for accurate autoguiding.

    How do the PLUS 115mm rings connect to telescopes that don't use the PLUS system?

    For compatibility with third-party hardware, the rings include central slots. This allows you to attach them to virtually any dovetail plate or support ring from other manufacturers using a single, centrally located screw.

    What are the benefits of the PrimaLuceLab PLUS system for mounting a guide scope?

    The PLUS system's main advantage is its rigidity. By using multiple screws for connections between components, it prevents any twisting or rotation between the guide scope and the main telescope. This modular system allows you to build a completely rigid and customized imaging train with plates, rings, and clamps that all work together seamlessly.

    I'm concerned about flexure in my guiding setup. How do the PLUS 115mm rings help prevent this?

    Flexure is minimized in two ways. First, the rings themselves are machined from a single block of aluminum, making them inherently stiff. Second, when connected to another PLUS component (like a dovetail plate) using the dedicated two-screw mounting points, they form a connection that cannot rotate or shift, which is a common source of differential flexure in guiding setups that rely on a single screw.

    What materials are used for the PrimaLuceLab PLUS 115mm rings?

    The rings are made from high-precision CNC-machined aluminum. They are then sandblasted for a uniform surface and finished with a hard anodizing process that provides a durable, scratch-resistant, and corrosion-resistant red finish.

    Can I adjust the balance of my guide scope when using the PLUS 115mm rings on a PLUS dovetail plate?

    Yes. When you attach the PLUS 115mm rings to a PLUS dovetail plate mounted on your main telescope, you can slide the rings along the length of the plate before tightening them down. This allows you to find the perfect position to balance the weight of your guide camera and scope, improving the tracking of your mount.
