  • PrimaLuceLab 145mm PLUS Support Rings

    The PrimaLuceLab 145mm PLUS Support Rings are a high-precision mounting solution for optical tubes with an approximate 145mm diameter. As a core component of the modular PrimaLuceLab Universal System (PLUS), these 145mm rings transform a standalone telescope into a rigid, expandable imaging platform.

    CNC-Machined Rigidity for 145mm Optical Tubes

    Unlike cast or bent-metal rings that can introduce flexure, each PrimaLuceLab PLUS ring is CNC machined from a solid block of aluminum. This process ensures exceptional mechanical precision and a stress-free grip on your optical tube, which is critical for maintaining alignment during long-exposure astrophotography. The rings are then sandblasted and hard-anodized, creating a durable, scratch-resistant surface that protects against oxidation.

    The PLUS System: A Modular Foundation for Your 145mm OTA

    These are more than just support rings; they are the foundation of a fully integrated mechanical system. The 145mm PLUS rings feature a pattern of threaded holes, unthreaded holes, and slots that allow for the direct attachment of other PLUS components. You can easily add dovetail plates above and below your telescope for increased stability or mount guide rings and other accessories without drilling or custom adapters.

    • Direct Component Mounting: Attach guide scopes, dovetail clamps, or an EAGLE computer directly to the rings for a compact and stable setup.
    • System-Wide Rigidity: Connecting PLUS plates to both the top and bottom of the rings creates a rigid cage around your telescope, minimizing tube flexure.
    • Cross-Brand Compatibility: Central slots are included to allow for the attachment of plates and accessories from other manufacturers, ensuring the rings can be integrated into your existing setup.

  • What is the primary purpose of the PrimaLuceLab 145mm PLUS Support Rings?

    The primary purpose of the PrimaLuceLab 145mm PLUS Support Rings is to securely mount a telescope with a 145mm diameter optical tube to a dovetail plate, while also providing a modular platform for attaching additional accessories like guide scopes, control computers, and secondary dovetail plates.

    How do the 145mm PLUS Support Rings improve my astrophotography setup?

    They provide a significant increase in mechanical rigidity compared to standard rings. By being CNC machined from solid aluminum, they eliminate flexure that can cause trailed stars during long exposures. The integrated PLUS system of holes and slots allows you to build a more compact and stable imaging train by attaching guiders and other accessories directly to the rings.

    Can I attach a guide scope to the PrimaLuceLab 145mm PLUS rings?

    Yes. You can attach guide rings directly to the top of the 145mm PLUS rings using the provided threaded holes. Alternatively, you can mount a PLUS dovetail plate on top of the rings and then attach your guide scope using a compatible dovetail clamp, allowing for easy adjustment and removal.

    Are the PrimaLuceLab 145mm PLUS rings compatible with non-PLUS dovetail plates?

    Yes. While designed for seamless integration with the PLUS system, the rings include central slots that allow you to fasten them to most standard Vixen or Losmandy-style plates from other manufacturers using standard screws.

    I have a telescope with a 140mm tube. Can I use the 145mm PLUS rings?

    The 145mm PLUS rings are designed for tubes with an approximate diameter of 145mm. A smaller 140mm tube may not be held securely without modification. It is always recommended to use rings that precisely match your optical tube's diameter for optimal stability and to prevent damage to the tube.

    How can I use the 145mm PLUS rings to mount an EAGLE computer on my refractor?

    The EAGLE computer shares the same PLUS mounting hole pattern. You can mount the EAGLE directly to the top of the 145mm PLUS rings. This creates an incredibly compact and integrated setup, minimizing cable drag and simplifying your entire imaging rig by placing the control unit right on the optical tube.
