SVBONY SV116 Adjustable Guide Scope Rings Kit for 43mm-70mm Telescope
The SVBONY SV116 Adjustable Guide Scope Rings Kit provides a rigid, adjustable mounting solution for guide scopes with tube diameters from 43mm up to 70mm. Each ring features three large 12mm knurled metal screws for precise alignment and a secure hold. With a total weight of just 168.4g (5.94oz) and standard M5 and M8 threads, this kit offers a stable, lightweight platform for autoguiding without adding significant load to your mount.
Solid Metal Build: Secure Adjustment with 12mm Knurled Screws
Constructed entirely from metal, the SV116 rings are built for stability and durability, eliminating flexure that can ruin a long exposure. The oversized 12mm adjustment screws are knurled for a positive grip, allowing you to make fine adjustments to your guide scope's alignment, even while wearing gloves on a cold night. The tips of these screws are inlaid with a soft Teflon material, which holds the guide scope firmly in place without scratching or marring its finish.
Flexible Mounting: 43mm-70mm Range for Guide Scopes
These rings are engineered to fit a wide variety of popular guide scopes and finders, accommodating any instrument with an outer tube diameter between 43mm and 70mm. The base of each ring is equipped with M8 threads, allowing for direct and secure attachment to most dovetail bars and mounting plates. This system enables you to mount a guide scope parallel to your main imaging telescope, a critical requirement for accurate autoguiding and astrophotography.

What size guide scopes will the SVBONY SV116 rings fit?
The SVBONY SV116 rings are designed for telescopes, guide scopes, or finders with an outer tube diameter ranging from 43mm to 70mm. This covers most small and medium-sized guide scopes commonly used for astrophotography.
Do the adjustment screws on the SV116 rings protect the telescope tube?
Yes. While the large 12mm screws are made of metal for durability, their tips feature Teflon inlays. This soft material prevents the screws from scratching or leaving pressure marks on your guide scope's finish while still providing a secure, non-slip grip.
How do I mount the SVBONY SV116 rings to my dovetail bar?
The base of each SV116 ring is drilled and tapped with M8 threads. You can use standard M8 bolts to attach the rings directly to a universal dovetail bar or another mounting plate that has corresponding holes.
Can I use the SVBONY SV116 rings to mount a 60mm guide scope on my 11-inch SCT?
Absolutely. A 60mm guide scope falls perfectly within the 43mm-70mm adjustable range of the SV116 rings. Mounting them on a dovetail bar attached to your SCT will provide a stable platform for autoguiding your imaging sessions.
How do the SVBONY SV116 rings help me center a guide star for autoguiding?
The three 12mm knurled screws on each ring allow for fine-tune adjustments. By selectively tightening and loosening the opposing screws, you can precisely aim the guide scope independently of the main telescope. This lets you easily center a suitable guide star on your autoguider's sensor without having to move your primary imaging target.
How much do the SVBONY SV116 rings weigh?
The net weight for the set is 168.4g (5.94oz). Their all-metal yet lightweight design adds rigidity without significantly increasing the payload on your telescope mount.
