  • PrimaLuceLab 235mm PLUS Support Rings

    The PrimaLuceLab 235mm PLUS Support Rings provide a rigid, CNC-machined mounting solution for optical tubes with a 235mm diameter, such as 200mm Newtonian reflectors, forming the foundation of the modular PrimaLuceLab PLUS system.

    CNC-Machined Rigidity for 235mm Optical Tubes

    Unlike standard cast or bent-metal rings that can introduce flexure into an imaging system, each PrimaLuceLab PLUS ring is precision-machined from a solid block of aluminum. This manufacturing process ensures perfect roundness and structural integrity, eliminating a common source of tracking errors and image shift during long exposures.

    The aluminum is then sandblasted to create a smooth, uniform surface and hard-anodized to increase surface hardness and protect against oxidation. This results in a pair of rings that not only provide a rigid connection to your mount but are also built to withstand years of use in the field.

    The PLUS System: A Modular Foundation for Your Imaging Rig

    These rings are a core component of the PrimaLuceLab PLUS (Prima Luce Universal System), an ecosystem designed for maximum mechanical flexibility. The rings feature a versatile pattern of threaded holes, unthreaded holes, and slots, allowing you to securely attach other PLUS components directly to them.

    You can mount PLUS dovetail plates both above and below the rings to create an exceptionally rigid structure. This also provides ample real estate for adding accessories like guide scopes with PLUS guide rings, dovetail clamps, or control units like the PrimaLuceLab EAGLE. Central slots are also provided to ensure compatibility with plates and accessories from other brands, allowing you to integrate these high-precision rings into any existing setup.

  • What telescopes are compatible with the PrimaLuceLab 235mm PLUS Support Rings?

    These rings are designed for any telescope optical tube with an outer diameter of approximately 235mm. They are a popular choice for 200mm (8") Newtonian reflectors, whose tubes are often manufactured to this dimension.

    How do the PrimaLuceLab 235mm PLUS rings differ from standard rings?

    The primary difference is in the manufacturing process and material. PrimaLuceLab PLUS rings are CNC-machined from a solid block of aluminum for maximum rigidity and perfect roundness. Standard rings are often cast, which can lead to imperfections and flexure. The PLUS rings also feature a comprehensive system of holes and slots for modular accessory attachment, which most standard rings lack.

    Can I mount a guide scope on the PrimaLuceLab 235mm PLUS rings?

    Yes. You can attach a second PLUS dovetail plate on top of the rings, and then mount your guide scope and guide rings to that plate. This creates a secure, no-flex platform for your autoguiding system.

    I have a 200mm f/5 Newtonian and want to add a Losmandy-style plate on top. Can I do this with the 235mm PLUS rings?

    Absolutely. The threaded hole pattern on the top of the PrimaLuceLab 235mm PLUS rings is designed to directly accept any PrimaLuceLab PLUS dovetail plate, including their Losmandy-style plates. This allows you to create a rigid top rail for mounting accessories.

    What is the PrimaLuceLab PLUS system?

    The PLUS (Prima Luce Universal System) is an extensive lineup of mechanically compatible components, including rings, dovetail plates, clamps, and guide rings. All elements share a standardized hole-spacing pattern, allowing you to build a completely modular and rigid support system for your telescope without any custom drilling or modification.

    I use accessories from another brand. Can I still attach them to the PrimaLuceLab 235mm PLUS rings?

    Yes. In addition to the PLUS-specific threaded holes, the rings feature central slots. These slots allow you to use standard screws to attach plates or other accessories from different manufacturers that may not conform to the PLUS hole pattern.
