PrimaLuceLab 134mm PLUS Support Rings

Yes, these rings are specifically designed for any telescope with an optical tube diameter of approximately 134mm. They provide a precise and secure fit for instruments of this size, ensuring a stable connection to your mounting system.

The Prima Luce Universal System (PLUS) is an ecosystem of high-quality mechanical components, including dovetail plates, clamps, guide rings, and support rings. All elements feature a standardized pattern of threaded holes and slots, allowing you to assemble a rigid, modular, and flexure-free support system for your astrophotography rig.

Absolutely. You can attach a PLUS guide ring directly to the top of the 134mm rings, or you can mount a Vixen or Losmandy style dovetail plate across the top of the rings first. This top plate then provides a platform to attach your guide scope, finder scope, or an EAGLE control unit.

Yes. The rings include central slots in addition to the PLUS-specific threaded holes. These slots are designed to allow you to attach plates or other accessories from different manufacturers using standard screws, offering excellent cross-brand compatibility.

Each ring is machined with high precision from a solid block of aluminum using CNC machines. They are then sandblasted for a smooth surface and hard-anodized, which increases the material's hardness and protects it from corrosion.

The primary advantages are rigidity and modularity. The CNC-machined construction prevents flexure that can ruin long exposures. The integration with the PLUS system provides a secure, standardized way to attach all your accessories, from guide scopes to computers, creating a more stable and organized imaging platform.
