Aluminum alloy finder/guide-scope mounting ring designed for secure, lightweight, adjustable support of 28–32 mm diameter optical tubes. Combines durability with easy setup so you keep your finder or guide scope aligned and protected during observing sessions. Key benefits Secure, stable grip: Six metal locking screws provide firm, even clamping to prevent rotation or slip while you point the telescope. Protects optics: Each screw has a non-slip protective pad to hold the tube without scratching or marring the finish. Lightweight durability: Made from high-quality aluminum alloy for long life without adding unnecessary weight to your telescope setup. Precise alignment and quick adjustments: The adjustable design and hand-accessible screws make it simple to fine-tune alignment in the field, improving pointing accuracy and framing. Broad compatibility: Fits finder scopes and guide scopes with outer diameters from 28 mm to 32 mm and mounts to a 35-mm sight/base slot. Main features Material: High-quality aluminum alloy — strong, corrosion-resistant, and lightweight. Locking system: Six metal screws for even pressure distribution and improved stability. Protective pads: Non-slip rubber or similar pads on each screw to prevent scratches and ensure a firm hold. Size range: Adjustable to accommodate 28–32 mm diameter finder or guide scopes. Base interface: 35-mm sight/base designed for direct mounting into the finder-slot of most telescopes. Tool-free fine tuning: Screws can be adjusted by hand for fast tensioning and realignment during observations. Typical applications Visual observing: Securely mount and align a finder scope before a night of planetary or deep-sky observation so you can locate targets faster and keep them centered. Astrophotography guiding: Use as a guide-scope ring to hold a guide camera or small guide scope steady while making fine adjustments for long exposure imaging. Public outreach and field setups: Quick, tool-free installation and robust clamping make this ring ideal for mobile setups, star parties, or educational demonstrations where fast alignment and durable handling are required. Installation and use Mount the 35-mm sight base directly into your telescope’s finder slot. Place your 28–32 mm finder or guide scope inside the ring and tighten the six metal screws evenly. Use the hand-adjustable screws to set the optimal clamping pressure and fine-tune alignment; protective pads prevent damage to the optical tube. Re-check alignment after travel or heavy handling to ensure continued accuracy. What makes this stand out Six-point metal locking gives superior stability compared with two- or three-screw designs. Protective pads maintain the condition of delicate optical tubes while delivering a secure hold. Simple, tool-free adjustments let you adapt quickly during observing sessions without compromising precision. Specifications Material: High-quality aluminum alloy Locking screws: 6 metal screws with non-slip protective pads Compatible tube diameters: 28–32 mm Mounting base: 35-mm sight/base for direct telescope finder-slot installation This mounting ring is suitable for both beginners and experienced observers who need a reliable, damage-free, and easily adjustable solution for mounting finder or guide scopes.
