Sky-Watcher 355mm Universal D Style Dovetail Plate

Sky-Watcher 355mm Universal D-Style Dovetail Plate – Versatile Mounting for Heavier Optical Tubes

The Sky-Watcher 355mm Universal D-Style Dovetail Plate offers a rugged, reliable solution for securely mounting your larger optical tube assemblies to any Losmandy-style (D-series) saddle. At 355mm (14 inches) in length, this dovetail plate provides ample surface area and rigidity for mid-to-large aperture refractors, Newtonians, SCTs, and astrographs.

Constructed from precision-machined, anodized aluminum, the 355mm Universal D-Style Plate delivers exceptional strength while keeping weight to a minimum. Its rigid, torsion-resistant design ensures your imaging or visual setup remains locked in place, minimizing unwanted flexure that can degrade long-exposure astrophotography or high-power planetary observing.

This plate is compatible with virtually all mounts that accept the popular D-series (Losmandy-style) dovetail format, including mounts from Sky-Watcher, Celestron, Losmandy, iOptron, and others. Its universal hole spacing accommodates a wide range of tube rings and accessories, making it an excellent choice for users who want a flexible mounting platform without sacrificing stability.

Whether you're building a new system from scratch or upgrading an existing rig, the Sky-Watcher 355mm D-Style plate is ideal for heavier OTA configurations where a narrow Vixen-style plate just won’t cut it. The additional length also allows for better balance, especially on longer tubes or setups with multiple accessories like guide scopes, filter wheels, or camera rigs.

Key Features:

• 355mm (14") length for superior stability and balance

• Machined aluminum body with green anodized finish for durability

• Compatible with all standard Losmandy-style D-series saddles

• Multiple mounting hole patterns for maximum compatibility with tube rings and accessories

• Excellent choice for astrophotography setups or heavier OTAs

If you're looking for a no-nonsense, rock-solid mounting plate that delivers professional-grade performance without breaking the bank, the Sky-Watcher 355mm Universal D-Style Dovetail Plate deserves a spot in your toolkit. It's built to handle the demands of modern amateur astronomy, whether you're imaging distant galaxies or chasing crisp planetary detail.
