We stock high quality Geoptik and Prima Luce Lab telescope tube rings from 80mm to 250mm in diameter, as well as for guide scopes up to 115mm in diameter. 


Geoptik produces a comprehensive line of Italian-made astronomy accessories. Their tube rings are CNC-machinedanodized aluminium for added strength and protection against corrosion, and feature plastic-tipped screws.

The Prima Luce Lab PLUS rings are the easiest solution for mounting your telescope tube or guide scope. These rings belong to the PLUS system (Prima Luce Universal System) which 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. Each component of the PLUS system is carved from aluminium blocks that are CNC machined. The aluminium is then sandblasted to achieve a very smooth surface finish and is anodized (hard anodizing) to increase the hardness of the material and to protect it from oxidation.
