If you want to install a giode telescope in parallel to the main one, guide rings offer the simplest and cheapest solution to make this. The Guide rings PLUS 115mm offer a high build quality and all the features useful for this application, allowing you to install guide telescopes such as diameter 80mm refractors.
Our expert comment:
These tube clamps with short Vixen-level prism rail can be used as guide scope rings for guidescopes of the appropriate size, but are also ideal as mountings for the William Optics finder (optical finder, upright and true-upside-down – see items 68628, 68629 and 68630).
They are the right mounting option for the William Optics holders of the ZenithStar and Gran Turismo models, especially for this optical finder. The tube clamps are not included in the scope of delivery of items 68628, 68629 and 68630!
