  • William Optics DSD 245 Plate

    The William Optics DSD 245 Plate is a rigid, 245 mm mounting solution that natively fits both Vixen-style and Arca-Swiss saddles, eliminating the need for adapters. Measuring 43.5 mm wide and weighing just 0.33 kg (0.72 lbs), it adds secure, full-contact support to your optical tube without consuming valuable payload capacity.

    The 245mm Vixen & Arca-Swiss Dual Saddle Plate

    This 245 mm plate is engineered with both the Vixen and Arca-Swiss dovetail profiles machined into a single, solid bar. This innovative dual-sided design allows you to move an optical tube assembly from a Vixen-style astronomical mount to a standard Arca-Swiss photographic tripod head in seconds, without ever changing the plate.

    The integrated design ensures a secure, full-contact connection in either saddle type. This prevents the flexure and instability that can occur when stacking multiple adapters to bridge the two most common mounting standards in astronomy and photography.

    Lightweight & Rigid at 0.33 kg

    At just 0.33 kg (0.72 lbs), the DSD 245 plate provides a solid mounting point for your hardware while preserving your mount's precious payload capacity for cameras and other accessories. Its 245 mm length offers ample surface area for secure tube ring placement, making it an ideal choice for balancing small to medium-sized refractors and other compact optical tubes.

    • Length (245 mm): Provides excellent stability for refractors up to the 100mm class or for perfectly balancing smaller instruments.
    • Weight (0.33 kg): Keeps your total setup weight low, improving tracking accuracy and responsiveness from your mount.
    • CNC Machined: Guarantees a precise fit in any compatible saddle, providing a reliable and non-slip connection.
  • What types of telescopes work best with the William Optics DSD 245 Plate?

    The William Optics DSD 245 Plate, with its 245 mm length, is ideally suited for small to medium-sized telescopes. This includes most short-tube refractors (like the William Optics RedCat or GT series), smaller Maksutov-Cassegrains, and camera lenses mounted via a lens collar.

    How does the dual Vixen/Arca-Swiss feature on the DSD 245 Plate benefit me?

    The primary benefit of the William Optics DSD 245 Plate is its universal compatibility. You can attach your telescope to an astronomical mount with a Vixen-style saddle for night imaging, then quickly detach it and mount it on a photographic ball head with an Arca-Swiss clamp for daytime use, all without tools or adapters.

    Will the 245 mm length of the DSD 245 Plate be sufficient for my William Optics GT81 refractor?

    Yes, the 245 mm length of the William Optics DSD 245 Plate is an excellent match for a telescope like the GT81. It provides enough length to adjust the position of the tube rings for precise balancing, which is critical for accurate tracking, especially when adding a guide scope or heavy camera.

    Can I mount the William Optics DSD 245 Plate directly to my camera for use with a telephoto lens?

    Yes, if your telephoto lens has a rotating tripod collar with standard 1/4"-20 mounting holes, you can attach the William Optics DSD 245 Plate. This setup allows you to mount a heavy lens and camera body securely on either a Vixen-style star tracker or a standard Arca-Swiss tripod head.

    What is the benefit of the William Optics DSD 245 Plate's 0.33 kg weight?

    At only 0.33 kg (0.72 lbs), the plate adds minimal weight to your imaging setup. This is crucial for smaller mounts and star trackers, as it leaves more of the mount's payload capacity available for your telescope, camera, and other accessories, leading to better tracking and stability.

    Is the William Optics DSD 245 Plate compatible with all Vixen and Arca-Swiss clamps?

    The William Optics DSD 245 Plate is designed to standard Vixen and Arca-Swiss specifications and is compatible with the vast majority of clamps on the market. However, due to minor variations between manufacturers, it's always good practice to ensure the clamp can open wide enough to accept the 43.5 mm plate width.
