  • Baader Guide Scope Rings BP I - 60-120mm

    The Baader Guide Scope Rings BP I provide a rigid, non-slip mounting solution for guide scopes with tube diameters from 60mm to 120mm. Each 28mm wide ring is machined from solid aluminum and features three oversized M10 adjustment screws with 10mm diameter, non-rotating, ball-bearing tips for precise, scratch-free alignment. Mounting is handled by a central ¼" photo thread and two 5mm through-holes, while four additional ¼" threaded surfaces allow for secure attachment of accessories.

    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.

  • What makes the Baader BP I rings better than cheaper guide scope rings?

    The primary advantage of the Baader BP I rings is the non-rotating, ball-bearing tips on the M10 adjustment screws. This design prevents the guide scope from shifting or being scratched during tightening, a common issue with simpler rings that use basic nylon-tipped screws. The solid aluminum construction and 28mm width also provide superior rigidity.

    Can I mount the Baader BP I rings on any dovetail bar?

    Yes. The base of each ring has a central ¼" photo-threaded hole and two additional 5mm through-holes. This combination allows you to securely bolt them to virtually any dovetail plate or mounting bar that accepts standard ¼"-20 or M5 hardware.

    Will the adjustment screws on the Baader BP I rings scratch my guide scope's finish?

    No. The screw tips are covered with a hard rubber sheath and, more importantly, they do not rotate when tightened. This non-rotating design ensures that the tip presses straight onto the tube without any twisting or scraping motion, protecting your telescope's paint and finish.

    What is the maximum diameter scope I can use with the Baader BP I rings?

    The Baader BP I rings are designed for tube diameters ranging from 60mm up to 120mm. The long M10 adjustment screws provide ample travel to accommodate any telescope within this range.

    How can I use the four extra threaded holes on the Baader BP I rings for a finder scope like the SkySurfer III?

    The four milled surfaces with ¼" threads are ideal for piggybacking accessories. To mount a Baader SkySurfer III or similar finder, you would attach the finder's mounting shoe or stalk to one of the threaded holes using a standard ¼"-20 bolt. This creates a solid, integrated pointing system directly on your guide scope assembly.

    Are the Baader BP I rings suitable for holding a small, wide-field refractor like a 70mm f/5 for piggyback imaging?

    Absolutely. While designed for guiding, the massive, 28mm wide construction of the Baader BP I rings makes them exceptionally rigid and perfectly capable of holding a small imaging refractor. A 70mm scope fits comfortably within the 60-120mm range, and the rings' stability will prevent flexure during imaging.
