Overview

The PLUS support rings can be used with various brands telescopes. With these rings you can install PrimaLuce PLUS plates or even guide rings both above and below the optical tube.

Like all the other elements of the PLUS series, these support rings are made with high mechanical precision (built with CNC machines from aluminum block) and specially designed to enable you to easily install other mechanical elements such as support rings, plates or dovetail clamps.

Description

The PLUS Support Rings are part of the PLUS (Prima Luce Universal System) which includes many guide rings, support rings, plates, adapters, and dovetail clamps to offer you the maximum freedom to build your mechanical system of support, depending on the application that you want to achieve. Indeed, all the PLUS elements have threaded holes, holes and slots suitable for connecting elements, always with maximum rigidity and comfort. Prima Luce designed many element for this purpose, including the PLUS Support Rings.

Each component of the PLUS system is made of aluminum blocks that are high precision CNC machined. The aluminum is then sandblasted to achieve a very smooth surface finish and is anodized (hard anodizing) to increase the hardness of the material and protect it from oxidation.

    Thanks to the particular design, the PLUS support rings are equipped with holes (above and below each ring) to permit the attachment of:

    1. Vixen or Losmandy plates below the rings to install the telescope on any mount
    2. PLUS guide rings (each ring can be fixed on the support ring with 2 screws)
    3. Vixen or Losmandy plates above the rings to increase the rigidity of the mechanical system and enable to install other accessories, such as dovetail clamps with guide rings to precisely adjust the position of the guide telescope.

    If you have other brands mechanical accessories, you can still use all the elements of the PLUS system. Indeed we have provided a series of central slots that allow, for example, to fix on these support rings plate or guide rings through a screw.

    Robert ★★★★★

    I was pleasantly surprised by how easily these rings adjusted to fit my telescope setup. The ability to stack a guide ring above and below the optical tube saved me from having to buy separate hardware. Definitely a solid upgrade for reducing flexure.

    Miles ★★★★★

    Bought these to mount a guidescope above my main tube, and the extra rigidity is noticeable right away. The fit is snug without needing to force anything, which made the whole setup quicker than I expected.

    Samuel ★★★★★

    Installing these rings was surprisingly easy—the threading lined up perfectly with my existing dovetail plate. They hold the tube securely without any shifting during tracking. Exactly what I needed for adding a guide scope.
