Orion Optics UK Dovetail Plates

Orion Optics UK dovetail plates connect telescope tubes and rings to the mount saddle. The range includes Losmandy dovetails and attachment plates from 250mm to 450mm, female Losmandy baseplates, a 355mm Sky-Watcher/Vixen dovetail plate, Celestron CGEM 3" wide plates in 250mm and 350mm, base plates, and a dovetail plate for Orion tube cradles.

Losmandy-style plates suit heavier tubes on larger mounts, while the Vixen-style plate fits lighter setups. Choose the length that gives room to balance your tube.
