Check my guiding setupThe PrimaLuceLab Guide Rings PLUS 80mm offer a high-precision mounting platform for guide telescopes such as 60mm diameter refractors. CNC-machined from a single block of aluminum, these 80mm rings integrate seamlessly into the PrimaLuceLab PLUS ecosystem for a rigid, zero-flexure setup.
Differential flexure is the primary source of poor guiding. These 80mm rings combat this by using a high-precision manufacturing process, where each ring is machined from a solid block of aluminum. This ensures perfect roundness and structural integrity that cast or bent metal rings cannot match.
The aluminum is then sandblasted for a smooth finish and hard-anodized to increase surface durability and prevent corrosion. Each ring includes three adjustment screws with nylon tips, allowing you to securely center your guide scope without marring its finish, ensuring your autoguiding system remains perfectly aligned with your main telescope all night.
As a core component of the PrimaLuceLab PLUS (Prima Luce Universal System), these 80mm rings are designed for maximum compatibility within the ecosystem. They feature threaded holes that allow direct, rigid connection to other PLUS components without the instability of stacked adapters.
You can mount the 80mm rings directly on top of an EAGLE computer, a PLUS dovetail plate, or PLUS support rings. For users with equipment outside the PrimaLuceLab system, a central threaded hole provides a secure connection point for attaching the rings to third-party plates or accessories using a single screw.
PrimaLuceLab does not publish the inner diameter. The rings are designed for guide telescopes such as 60mm diameter refractors, held by the support screws.
You can install the 80mm guide rings directly above the EAGLE using the 2 additional plates and the 4 M5x12 screws supplied in the package; the plates provide a flat base for optimal connection.
Yes. While designed for the PLUS system, each 80mm ring includes a central threaded hole. This allows you to mount the rings to a third-party dovetail plate or support ring using a standard screw, offering broad compatibility.
The rings are CNC-machined from a solid block of aluminum. This process ensures high precision and rigidity. They are then sandblasted for a smooth surface and hard-anodized to protect against scratches and oxidation.
Yes, absolutely. The 60mm CompactGuide scope comes standard with two 80mm PLUS guide rings, and these rings are designed for guide telescopes such as 60mm diameter refractors. The three-point adjustment screws allow you to securely center the guide scope inside the rings.
The PLUS system is a modular ecosystem of plates, rings, and clamps that connect together with multiple screws, not just one. For the 80mm guide rings, this means you can create a completely rigid imaging train from your main telescope to your guide scope, eliminating a common source of flexure that can ruin long exposures.
