Need help with Support rings?
The PrimaLuceLab PLUS Support Rings are precision mechanical rings designed to mount optical tubes into the PrimaLuceLab PLUS system.
Available in a wide range of diameters, these rings allow you to connect a telescope to Vixen or Losmandy dovetail plates, add a top plate for extra rigidity, or mount accessories such as guide rings, dovetail clamps, and EAGLE control units.
Each ring is CNC-machined from aluminium, sandblasted for a smooth finish, and hard anodised to improve surface durability and oxidation resistance.
The rings include threaded holes and slots on both the top and bottom, giving you flexibility when building a rigid, clean, and modular telescope setup.
Size note: choose the support ring size that matches the outside diameter of your telescope tube, not the optical aperture. If you are unsure, measure the tube diameter carefully before ordering.
