ADM D Series Dovetail Bar

The ADM D Series is designed specifically for Losmandy-style saddle plates. It is compatible with a wide range of mounts, including the Losmandy G-11, Celestron CI700, Parallax, William Optics, Astro-Physics, Astro-Tech, and Takahashi systems.

The ideal length depends on the physical size of your optical tube and the amount of balancing room you need. A longer bar provides more surface area for adjusting the balance point of your telescope, which is particularly important for imaging rigs with heavy cameras or guide scopes.

Yes, the bar is engineered with versatile hole spacing configurations. It accommodates both standard imperial spacing and metric options, including specific hole patterns for Takahashi equipment, ensuring it fits most third-party rings without needing custom modifications.

The thickness determines the overall rigidity of your mounting system. The 0.75-inch option provides extra stiffness, which is recommended for larger, heavier telescopes or complex imaging setups where minimizing flexure is critical for sharp, long-exposure photography.

In most cases, no. Because the bar features a variety of pre-drilled hole patterns, it is designed to bolt directly to the majority of standard telescope rings on the market. Just verify your ring's hole spacing against the bar's specifications before purchasing.
