How do the Baader Size III Guidescope Rings prevent scratching my telescope?
The rings feature three M10 adjustment screws with non-rotating tips. Each tip has a ball-bearing surface made of V2A steel and is covered by a hard rubber sheath. Because the tip doesn't spin as you tighten it, it provides a firm grip without marring or scratching your telescope's tube.
What are the mounting points on the outside of the Baader Size III rings for?
The exterior of each ring has four milled flat surfaces with standard ¼" photo-threaded holes. These allow you to "piggyback" additional accessories, such as a finderscope, a small camera, or other aiming devices, directly onto the guidescope assembly.
Are these Baader guidescope rings stable enough for long-exposure guiding?
Yes. They are machined from solid, turned aluminum to be massive and rigid. This construction, combined with the 28mm wide profile and secure, non-slip adjustment screws, minimizes flexure and ensures your guide scope remains perfectly aligned throughout a long imaging session.
Can I mount these Baader rings on a standard Vixen or Losmandy dovetail bar?
Yes, the base of each ring is designed for versatile mounting. It includes a central standard ¼" photo-threaded connection and two additional 5mm through-holes, providing multiple options for securely bolting the rings to most common dovetail plates and bars.
What is the benefit of the large knobs on the Baader Size III rings?
The large, knurled adjustment knobs are designed for easy use, even when wearing gloves in cold weather. They provide excellent leverage, allowing you to make fine, controlled adjustments to the guidescope's alignment without requiring tools.
If I'm using a heavy guidescope like a small refractor, will the Baader Size III rings hold it securely without flexure?
Absolutely. The rings are engineered from solid aluminum for maximum rigidity. Their "massive" design is specifically intended to support heavier guide telescopes without introducing sag or flexure, which is critical for maintaining precise tracking during astrophotography.
