PLUS (Prima Luce Universal System) is a complete mechanical system that includes dovetail plates, support rings, guide rings and dovetail clamps that offers you the greatest freedom to build your support mechanical system, depending on the application you want to accomplish.
The elements of the PLUS system are made with high mechanical precision (manufactured by CNC machines), treated and anodized to increase the hardness of the material and protect it from corrosion. All our PLUS accessories are however compatible with other brands elements, which can also be connected with the holes and the slots in the center.
The PLUS curved blocks can be easily installed on any telescope. Simply remove the screws already on the telescope and fix the curved blocks (one in front, one in rear of the optical tube) and secure with the same screws.
When we install many instruments (for example telescope with guide scope in parallel) on the mount, it can happen that they are too close together, and that some element touches the others.
