Orion 120mm Guide Scope Rings with Dual-Width Clamps

The Orion 120mm Guide Scope Rings with Dual-Width Clamps will be able to take your deep-sky astrophotography endeavors to the next level! This mounting system is durable and versatile and fits a wide range of guide scopes, from 65mm to 115mm in outside tube diameter.

These 15mm-wide anodized aluminum rings have an inside diameter of 120mm (4.7″) and are machined with three plastic-dipped, 35mm-length metal screws that allow you to easily adjust the aim of your guide scope. The plastic tips ensure a good grip on the scope and prevent you from ruining its surface. The 120mm Guide Scope rings are the perfect match for an 80mm guide scope, but can easily accommodate guide scopes with tube diameters than range from 65mm to 115mm.

Each guide scope ring is mounted on a riser block, which is attached to a black-anodized aluminum dovetail clamp that is machined with two grooves that can accommodate either Vixen or Losmandy style dovetail plates. The clamps expand using internal spring action when the lock knob is loosened. Each clamp has a large aluminum knob that makes it easier to install and lock down the clamp.

Each ring and clamp assembly comes fully assembled. This set includes two (2) complete ring and clamp assemblies.

• This pair of aluminum ring and clamp assemblies provide a rock-solid mounting system for guide scopes ranging from 65mm-115mm in tube diameter
• Dual-width clamps allow you to attach to both Vixen and Losmandy style dovetail plates
