About the PLUS System
The PrimaLuce PLUS (Prima Luce Universal System) is a system of dovetail bars and rings for telescopes that were designed to connect telescopes and accessories modularly, but in a stable manner without flexures. All PLUS components, including the PLUS Support Rings, are made of aluminum blocks that are high precision CNC machined. The aluminum is then sandblasted to achieve a very smooth surface finish and is anodized (hard anodizing) to increase the hardness of the material and protect it from oxidation. All PLUS elements are designed to be connected to each other with at least two M6 screws to ensure the greatest possible strength and the total absence of flexure.
