About this product

Model:  pl_pllansu134p
Part Number:  PLLANSU134P

Premium quality 134mm PLUS tube rings from Primaluce Lab.

The 134mm PLUS support rings can be used with telescopes of approximately 134mm diameter, including the SkyWatcher Esprit 100 and similar sized telescopes.

The 134mm PLUS support rings are part of Primaluce Labs PLUS system (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. All the PLUS elements have threaded holes, holes and slots suitable for connecting elements, always with maximum rigidity and fit.

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

Thanks to the particular design, the 134mm 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 accessories, you can still use all the elements of the PLUS system, for example by use of a series of central slots that allow fixing guide rings or dovetail plates through a screw.

Great-looking, shame they donít work...
Wednesday, 3 April 2019  | 

Bought these rings to replace the standard tube rings on my new Esprit 100. They look great and are a good match with my Avalon Linear mount. Unfortunately, they just donít grip the scope tube, no matter how much you tighten them; after a few days, the scope has slid down to the dew shield stop. Iíve had to resort to adding thin rubber strips inside the rings to prevent the scope from sliding down under its own weight when parked - and this is before loading it up with a camera, filter wheel etc. Not what youíd expect from a supposedly premium product. If iíd known I was going to have to faff about like that, Iíd have stuck with the rings that came with the scope.
