PLUS is the system of dovetail bars and rings for telescopes designed by PrimaLuceLab in order to connect in a modular way telescopes and accessories in a stable manner and without flexures. All elements are made of high-strength aluminum, sandblasted, with high thickness red anodizing treatment. All PLUS elements are designed to be connected to each other always with at least two screws (M6) to ensure the greatest possible strength and the total absence of flexions, very important for astrophotography.
