The support rings PLUS 125mm can be used with different brands telescopes (for example refractors 120-130mm in diameter) with tube approximately 125mm in diameter. With this rings you can install both above and below the optical tube our PLUS plates or even guide rings. Compatible with telescopes by various brands, such as: Takahashi FSQ106ED, Takahashi FSQ106EDX, Takahashi TSA120. Like all the other elements of the PLUS series, these 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 plates, guide rings or dovetail clamps. Weight: 0.6 kg.
The 125mm PLUS support rings are part of our system PLUS (Prima Luce Universal System) which includes a large variety of support rings, plates, guide rings 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.
For this application, we designed many elements, including the 125mm 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 125mm PLUS support rings are equipped with holes (above and below each ring) to permit the attachment of:
- Vixen or Losmandy plates below the rings to install the telescope on any mount
- PLUS guide rings (each ring can be fixed on the support ring with 2 screws)
- 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.
How to use PLUS support rings with PLUS dovetail bars, guide rings and EAGLE
PLUS support rings are available in different diameters in order to fit different telescopes. All of them are provided with holes and threaded holes for M6 screws in order to let you easily connect to all the other PLUS elements like dovetail bars, guide rings and EAGLE control units. In fact we specifically designed the PLUS system to allow you connect all the elements with at least 2 screws and avoid flexures. Let’s see how to use PLUS support rings with PLUS dovetail bars, guide rings and EAGLE.
In this video Filippo shows you how to connect PLUS support rings to the other PLUS elements like dovetail bars, guide rings and EAGLE control units:
In order to connect PLUS support rings to PLUS Vixen-style dovetail bars, you can use 2 M6x12 screws, inserting every screw from the internal part of the ring and screwing it into the corresponding M6 thread in the Vixen-style dovetail bar. This way the M6 screw head will be inside the ring and it won’t touch the telescope tube.

Instead, if you have a PLUS Losmandy-style dovetail bar, you can use 2 M6x12 screws for every support ring, inserting the screw from the bottom side of the bar in the corresponding passing holes. This way the M6 screw head will be inside the dovetail bar and it won’t touch the mount head when you will connect the dovetail bar to the clamp.

If you want to have a guide telescope in parallel to the main telescope, you can install the PLUS guide rings (that are available in 80mm and 115mm diameters) above the PLUS guide rings. In order to do this, you can use 2 M6x8 screws for every guide ring and insert every screw from the internal part of the support ring.

PLUS support rings are designed also to let you connect the EAGLE directly on top of them. This way, together with the dovetail bar installed below the PLUS support ring, you create a cage around your telescope and avoid any flexure. In order to connect the EAGLE to the PLUS support ring, you can use 2 M6x10 screw for every ring, inserting every screw from the internal part of the ring. Just note that, in order to connect EAGLE to PLUS support rings, avoid to use too long screws that may touch the internal electronics of the EAGLE. Threaded part of the screw that exits from the support ring has to be no longer than 6mm.
