William Optics Low Latitude Vixen Base Mount & Red Extension Bar

Standard star tracker bases often struggle to reach the low angles required for polar alignment when you are near the equator. This mount is specifically engineered to handle the 7°-34° latitude range, allowing you to achieve precise alignment where standard bases physically cannot tilt far enough.

This base is designed for popular portable trackers, specifically the iOptron SkyGuider Pro and the Sky-Watcher Star Adventurer 2i. It uses a standard Vixen-style saddle, making it a direct fit for these systems.

The extension bar adds four inches to your counterweight shaft. This extra length provides better leverage for balancing heavier camera setups or longer lenses, which helps reduce strain on your tracker's motor and improves tracking accuracy.

Yes, it is a significant improvement over standard single-screw clamps. By distributing pressure evenly across the dovetail bar rather than pushing it against a single point, it prevents marring or scratching your equipment while ensuring a much more secure, wobble-free lock.

Not at all. It features dedicated fine-adjustment knobs for both altitude and azimuth, which allow you to make micro-movements during polar alignment without having to loosen the main locking bolts. This makes the process much more stable and less frustrating.
