William Optics Losmandy-Style Dovetail Plate

Losmandy-style, or D-Series, refers to a specific, wider dovetail mounting standard that provides a larger surface area than the smaller Vixen-style plates. This design is generally preferred for larger, heavier telescopes because it offers superior stability and reduces flexure during long-exposure imaging.

Yes, this is a universal Losmandy-style plate designed to be compatible with a wide range of refractors from various manufacturers. As long as your telescope rings or mounting hardware are compatible with the D-Series standard, this plate will work.

The 400mm length provides a generous range for sliding your telescope forward or backward on the mount saddle. This extra length is particularly helpful for balancing heavier setups or those with accessories like guide scopes and cameras attached.

While the gold finish is a signature William Optics look, the anodizing process also serves a functional purpose by hardening the aluminum surface. This makes the plate more resistant to scratches, corrosion, and the general wear and tear of field use.

No, this plate is specifically engineered for Losmandy (D-Series) saddles. It will not fit into a standard Vixen-style saddle, so ensure your mount is compatible with the wider D-Series format before purchasing.
