Sky-Watcher Dovetail Bar for Quattro 300 D-Style - Black

The Sky-Watcher Dovetail Bar for Quattro 300 is a professional-grade D-style mounting plate designed specifically for high-capacity mounts like the EQ6, EQ8, and other wide-style heads. Featuring a robust 40 cm overall length and a substantial 100mm width, this plate provides the expansive surface area necessary to support large optical tubes with maximum stability. It is uniquely crafted with a super-rigid curved metal extrusion design, which offers enhanced resistance to flexing or bending under heavy loads. Anodized in a sleek black finish, the bar combines long-term durability and corrosion protection with a stylish aesthetic that complements professional-grade astronomical equipment.

Despite its sturdy construction and 400mm span, the mounting plate maintains a lightweight design at only 920 grams, ensuring ease of handling and transport. It features four mounting bolt holes with a center-to-center spacing of 360mm in length and 90mm in width, facilitating a secure and reliable connection that minimizes any chance of slippage or movement. This adherence to the standard Losmandy mounting dimensions ensures wide-ranging compatibility, making it an essential foundation for large reflectors or complex imaging rigs. By providing a secure attachment point, this dovetail allows for precise alignment and a vibration-free observing experience.

Product Features in Detail

Optimized for Large-Aperture Optics

This 40cm plate is specifically built to handle the torque and weight of the Quattro 300 reflector. Its extra length is vital for achieving balance on the declination axis, especially when using heavy specialized cameras or coma correctors at the front of the telescope.

Super-Rigid Curved Extrusion

Unlike flat plates that can vibrate under load, the curved profile of this dovetail increases its mechanical strength. This "arch" design acts as a structural reinforcement, ensuring that the telescope remains perfectly still during long-exposure astrophotography.

Precision Mounting Alignment

With a standardized 360mm x 90mm bolt pattern, this plate offers a seamless fit for Sky-Watcher tube rings. This precise spacing ensures that the weight of the telescope is distributed evenly, preventing stress points on the tube assembly.

Professional "D-Style" Interface

The D-style format is the preferred choice for serious astronomers. The 100mm width provides a much wider contact area than standard Vixen plates, virtually eliminating "torsional flex" where the telescope might otherwise twist slightly during high-speed slews.

Corrosion-Resistant Black Anodization

The black anodized finish is not just aesthetic; it’s an electrochemical process that hardens the surface of the aluminum. This prevents the plate from "galling" or being chewed up by the mount's locking pins, maintaining a smooth slide for years of use.

Massive Payload, Minimal Weight

By utilizing a high-strength aluminum alloy and a smart extrusion shape, Sky-Watcher has kept the weight under one kilogram. This allows you to utilize more of your mount's weight capacity for actual gear, like guide scopes and filter wheels, rather than "wasting" it on heavy mounting hardware.
