Baader Guide Scope Rings BP I - 60-120mm

Rock-Solid Support for Guide Scopes from 60mm to 120mm

Machined from solid, turned aluminum, these 28mm wide rings provide a massive, stable platform that eliminates flexure in your guiding setup. The wide contact surface and robust build are designed to securely hold guide scopes ranging from compact 60mm models to larger 120mm refractors, ensuring your autoguiding remains precise throughout a long imaging session.

M10 Adjustment Screws: Precision Pointing Without Tube Damage

The core of the BP I design is its advanced adjustment system. Three large M10 screws on each ring allow for fine, deliberate alignment of the guide scope. Crucially, each 10mm diameter screw tip features an internal ball-bearing surface made of V2A steel, which prevents the hard rubber contact pad from rotating as you tighten it. This eliminates the torsional stress and paint marring common with simpler nylon-tipped screws, keeping your guide scope held firmly without risk of scratches or slippage.

Integrated Accessory Mounting: 4 Additional 1/4" Threaded Ports

Beyond their primary function, the BP I rings serve as a versatile mounting hub. Each ring features four milled planar surfaces on its outer diameter, each equipped with a standard ¼" photo-threaded hole. This allows you to piggyback additional accessories directly onto the rings, such as a finderscope, a WiFi adapter, or cable management hardware, creating a clean and integrated imaging train.

Baader BP I vs. Standard Rings: The Advantage of Non-Rotating Tips

While many guide rings use a simple bolt with a fixed nylon tip, the Baader BP I rings incorporate a superior mechanical design. The difference is most apparent during final adjustments.

• Standard Rings: As you tighten a standard screw, the tip twists against the telescope tube. This can cause the guide scope to "walk" out of position, mar the paint finish over time, and apply uneven, slipping pressure.
• Baader BP I Rings: The ball-bearing mechanism isolates the rotational force. Only pure linear pressure is applied to the guide scope, resulting in an absolutely solid, non-slip grip that holds alignment perfectly and protects your equipment's finish.
