  • PrimaLuceLab 180mm PLUS Support Rings

    Designed for optical tubes with a 180mm outer diameter, the PrimaLuceLab 180mm PLUS Support Rings are CNC-machined from a single block of aluminum to provide a rigid, zero-flexure mounting point for premium instruments like the Takahashi TOA150.

    180mm Rings for Takahashi TOA150 and Other OTAs

    These support rings provide the fundamental connection between your telescope and the rest of your imaging system. With a precise 180mm internal diameter, they are engineered to securely hold high-end refractors like the Takahashi TOA150, transforming a standalone optical tube into a versatile instrument ready for any mount or accessory configuration.

    Expand Your Rig with the PLUS Mounting System

    As a core component of the Prima Luce Universal System (PLUS), these rings unlock a complete ecosystem of compatible hardware. The system of threaded holes, plain holes, and slots allows you to rigidly attach PLUS dovetail plates, guide rings, and other accessories above and below your main telescope. This modularity enables you to build complex setups, such as mounting a guide scope or piggybacking a second imaging telescope, with maximum stability.

    CNC-Machined Aluminum for Maximum Rigidity

    Each ring is machined from a solid block of aluminum using high-precision CNC equipment, ensuring perfect roundness and structural integrity. The aluminum is then sandblasted for a smooth finish and hard-anodized to increase surface hardness and protect against oxidation. This manufacturing process results in a support system that eliminates flexure, a critical requirement for long-exposure astrophotography.

  • What telescopes are compatible with the PrimaLuceLab 180mm PLUS Support Rings?

    These rings are designed for any telescope optical tube with an outer diameter of exactly 180mm. They are an ideal match for premium refractors such as the Takahashi TOA150.

    How do these 180mm PLUS rings improve my imaging setup over stock rings?

    The primary advantage is their integration into the PrimaLuceLab PLUS system. Unlike stock rings, the PLUS system's universal hole and slot pattern allows you to rigidly attach a wide range of accessories like guide rings, dovetail plates, and clamps on both the top and bottom, creating a more stable and versatile imaging platform.

    Can I mount a guide scope on the PrimaLuceLab 180mm PLUS rings?

    Yes. By attaching a PLUS dovetail plate to the top of the 180mm rings, you can then add PLUS guide rings or a dovetail clamp to hold your guide scope. This creates a secure, no-flexure autoguiding setup directly coupled to your main telescope.

    Are the PrimaLuceLab 180mm PLUS rings compatible with non-PLUS dovetail plates?

    Yes, they offer broad compatibility. The rings include a series of central slots that allow you to attach plates from other manufacturers using standard screws, giving you the flexibility to integrate them into an existing setup.

    What is the benefit of the hard anodized finish on these 180mm rings?

    Hard anodizing increases the surface hardness of the aluminum, making the rings highly resistant to scratches and wear. It also provides superior protection against corrosion and oxidation compared to standard paint or powder coating, ensuring a long service life even in damp observing conditions.

    I have a Takahashi TOA150. What else do I need to mount it on a Losmandy-style mount using these rings?

    To mount your Takahashi TOA150 on a Losmandy-style mount, you will need to attach a PrimaLuceLab PLUS Losmandy-style dovetail plate to the bottom of these 180mm rings. A plate length of 350mm or longer is typically recommended for a telescope of this size to ensure proper balance.
