The 105mm PLUS support rings are meticulously crafted to complement any apochromatic telescope equipped with a plate for photographic tripod connections or Vixen clamps. By adding these rings to your setup, you unlock a world of possibilities for your telescope, allowing it to be used on a variety of mounts or in parallel configurations. These rings are universally compatible with optical tubes having a 105mm diameter.

These 105mm PLUS support rings are an integral part of our comprehensive PLUS system (Prima Luce Universal System), which encompasses a diverse range of support rings, plates, guide rings, and dovetail clamps. This system empowers you with the utmost freedom to construct your customized mechanical support system, tailored precisely to your specific needs. Every PLUS system component features threaded holes, openings, and slots, facilitating secure connections while ensuring maximum rigidity and user comfort.

In crafting the 105mm PLUS support rings and other PLUS system components, we employ precision CNC machining on high-grade aluminium blocks. These aluminium surfaces undergo a meticulous sandblasting process to achieve a flawlessly smooth finish and are then treated with hard anodizing to enhance material hardness and safeguard against oxidation.

The ingenious design of the 105mm PLUS support rings incorporates strategically positioned holes both above and below each ring. These holes enable you to:

1. Attach Vixen or Losmandy plates beneath the rings, enabling the telescope's mounting on various types of mounts.
2. Secure PLUS guide rings to the support rings using two screws for precise guiding applications.
3. Add Vixen or Losmandy plates above the rings, bolstering the overall mechanical system's rigidity. This also simplifies the installation of other accessories such as dovetail clamps with guide rings, facilitating precise adjustments for your guide telescope's positioning.
