The 95mm PLUS support rings are designed for optical tubes with a diameter of Ø95mm. These rings belong to the PLUS system (Prima Luce Universal System) that includes a large variety of telescope rings, bars, guide rings and dovetail clamps. The rings have a system of drilled and threaded holes that maximize the compatibility between parts, allowing several mechanical combinations and assembly solutions. 

They are compatible with several telescopes such as the Takahashi FSQ85, Takahashi FS-78, Takahashi FC-100DF and DL.Prima Luce Lab 85mm telescope rings

Each component of the PLUS system is carved from aluminium blocks with CNC machines. Then, the aluminium is sandblasted to achieve a very smooth surface finish and it is anodized (hard anodizing) to increase the hardness of the material and to protect it from oxidation.

Due to the particular design, the 95mm PLUS support rings are equipped with tapped holes (above and below each ring) to allow the attachment of:

  1. Vixen or Losmandy bars 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 bars above the rings to increase the rigidity of the telescope assembly and to allow the installation of other accessories such as dovetail clamps.

    great rings for my Takahashi FSQ-85

    I have been using the Takahashi clamshell for my FSQ so far, but have been looking around for mounting rings as this makes it easier to connect the guider and other equipment.

    These are very well built and I also like the coloring. I have mounted the rings on a 350mm Losmandy type PLUS dovetail, as the FSQ with imaging equipment is quite back-heavy and this way i can still balance the scope without issues.
    Do get the 10mm spacers so you can mount the dovetail, else the focuser and the dew shield will be in the way.
