  • PrimaLuceLab 125mm PLUS Support Rings

    The PrimaLuceLab 125mm PLUS Support Rings are CNC-machined from a single aluminum block to provide a flex-free mounting foundation for optical tubes with a 125mm diameter. These rings integrate seamlessly into the PrimaLuceLab Universal System (PLUS), offering a matrix of threaded holes to attach dovetail plates and guide rings to premium 125mm-class refractors like the Takahashi FSQ106ED.

    CNC-Machined Rigidity for 125mm OTAs

    Unlike cast or bent-metal rings that can introduce flexure, each 125mm PLUS ring is machined from a solid block of aluminum for maximum structural integrity. This high-precision manufacturing ensures your optical tube is held perfectly parallel and secure, which is critical for maintaining alignment in an imaging system. The rings are then sandblasted and hard-anodized to protect against scratches and corrosion.

    These rings are specifically designed to fit high-end refractors with a 125mm tube diameter, including the Takahashi FSQ106ED, FSQ106EDX, and TSA120. This precise fit ensures a secure grip without damaging the telescope's finish.

    The PLUS System: A Modular Foundation for Your Imaging Rig

    These rings are a core component of the PrimaLuceLab PLUS (Prima Luce Universal System), an ecosystem of interoperable plates, clamps, and rings. A generous pattern of threaded holes, plain holes, and slots on the rings allows for the rigid attachment of other PLUS components, such as Vixen or Losmandy style dovetail plates, on both the top and bottom of your telescope.

    This modularity lets you build a compact and stable imaging platform. You can easily add guide rings for a separate guide scope or mount an EAGLE control unit directly to the top of the rings. For those with accessories from other brands, central slots provide compatibility for attaching third-party plates or rings using standard screws.

  • What telescopes are compatible with the PrimaLuceLab 125mm PLUS rings?

    These rings are designed for any telescope with an optical tube diameter of approximately 125mm. They are a confirmed fit for premium refractors such as the Takahashi FSQ106ED, Takahashi FSQ106EDX, and Takahashi TSA120.

    How do I attach a guide scope using the 125mm PLUS rings?

    You can attach a guide scope by mounting a second dovetail plate (Vixen or Losmandy style) to the top of the 125mm PLUS rings. Then, you can attach guide rings with a corresponding dovetail clamp to that plate. This creates a highly rigid, dual-scope setup.

    How do the PrimaLuceLab 125mm PLUS rings attach to my mount?

    The rings themselves do not attach directly to a mount. You must first bolt a dovetail plate (such as a Vixen-style or Losmandy-style PLUS plate, sold separately) to the bottom of the rings. This plate then slides into the saddle clamp on your astronomical mount.

    Are these 125mm rings compatible with non-PrimaLuceLab dovetail plates?

    Yes. While designed for the PLUS system, the rings feature a series of central slots that allow you to attach plates and other accessories from different manufacturers using standard screws, providing a high degree of cross-brand compatibility.

    I have a Takahashi FSQ106ED and want to add an EAGLE computer. Are the 125mm PLUS rings the right choice?

    Absolutely. The 125mm PLUS rings are the ideal starting point. You can attach the FSQ106ED within the rings, connect a Losmandy or Vixen plate to the bottom for your mount, and then bolt the EAGLE computer directly to the threaded holes on top of the rings for a clean, integrated setup with minimal cable clutter.

    Will the PrimaLuceLab 125mm PLUS rings fit a refractor with a 130mm tube?

    No, the 125mm internal diameter is fixed and cannot accommodate a larger 130mm tube. It is crucial to measure your telescope's tube diameter accurately before purchasing to ensure a proper fit. PrimaLuceLab offers PLUS rings in a wide variety of other sizes.
