William Optics Slide-base 50mm Guiding Rings - Blue
The 2019 All-New Slide-Base 50mm Guiding Rings are designed specifically for William Optics 50mm guidescopes with an outer tube diameter of 54.8 mm. Each ring is lined with felt on the inside for secure, scratch-free support and features a no–alignment-screw design for simplicity and stability.
These blue 50mm guide rings are engineered to fit directly into the slide-base handle found on select William Optics telescopes, including models like the GT71 Triplet Refractor, Z81 Doublet Refractor, and other compatible scopes. They provide an easy way to replace the standard WO slide-base finder with your preferred 50mm finder or guide scope.
