Use the Losmandy Dovetail Saddle Adapter Bracket for mounting your OTA using two of the most popular dovetail configurations. Engineered to accept the large Losmandy and the smaller Vixen-style dovetail plates the bracket simply bolts to your OTA or rings using the existing mount holes, and allows you to quickly attach and break-down your rig without tools - simply loosen the included locking thumbscrew. Made of a lightweight and durable aluminum alloy, it has a black anodized finish that resists corrosion and scratching.
