The combination of thumbscrews and screws keeps the dovetail base firmly anchored to your telescope for stable, worry-free observation. Broad compatibility: Designed as a flat base finder, it integrates cleanly with a wide range of brackets and dovetail plates. Use it wherever a flat-base dovetail interface is required to increase the flexibility of your optical train. Compact and portable: Measuring about 40 x 44 x 16 mm and weighing ~40 g, the base is easy to carry and handle. Its small footprint makes installation fast and unobtrusive during field use or at crowded observing events. Clear benefits for your setup: Reduces vibration and movement for mounted finders or accessories. Keeps added mass minimal so balance and tracking performance are preserved. Quick thumbscrew adjustments speed setup and teardown without tools. Typical applications: Mount a finder scope or red-dot finder to a telescope tube for accurate target acquisition. Attach a lightweight guide scope or auxiliary optical accessory for astrophotography setups where low weight and secure fixation matter.
