The 90mm PLUS support rings are designed for the AIRY APO80 apochromatic telescope that has plate for photographic tripods connection or for Vixen clamps. Adding these rings, you can broad the possibilities of use of this telescope as it becomes possible, for example, the installation also on other mounts or to install telescopes in parallel. These rings can be used with PrimaLuceLab AIRY APO80 optical tubes or with other telescopes with 90mm in diameter optical tube.
The 90mm 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.
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 90mm 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. A series of central slots allow, for example, to fix on these support rings plate or guide rings through a screw.
