  • Losmandy style dovetail plate 645mm PLUS

    The PrimaLuceLab Losmandy style dovetail plate 645mm PLUS is designed to provide a long, rigid mounting platform for large optical tubes on mounts accepting a Losmandy-style bar. As a core component of the PrimaLuceLab PLUS ecosystem, it enables complex accessory configurations and offers extensive mounting flexibility for support rings, guide scopes, and automated imaging tools.

    Long-Format Support and CNC Aluminum Build

    This 645mm plate provides the extended length required to securely mount large telescopes, allowing for widely spaced support rings that dramatically increase stability and minimize flexure. Each plate is CNC machined from a single block of aluminum, ensuring precise tolerances and structural integrity. The surface is then sandblasted for a smooth finish and hard-anodized to protect against scratches and oxidation.

    The PLUS System: A Rigid, Modular Foundation for Your Telescope

    The Losmandy style dovetail plate 645mm PLUS is a fundamental part of the Prima Luce Universal System (PLUS), an ecosystem of plates, rings, and clamps designed for maximum rigidity and modularity. The plate features a pattern of threaded holes and slots that allow you to securely attach other PLUS components without drilling or custom fabrication. This system is also designed for cross-compatibility, with central slots that allow you to attach support or guide rings from other manufacturers.

    Automated Flats: An Integrated Solution for the 8" EdgeHD

    This plate enables a uniquely integrated, remote-imaging workflow for owners of Celestron EdgeHD 8" telescopes. When mounted in parallel to the main optical tube using optional PLLSAG925 curved blocks, the 645mm plate provides the necessary platform to attach the ALTO-2 cover motor and GIOTTO 255 smart flat field generator. This creates a fully motorized telescope cap, allowing you to capture flat calibration frames remotely without being physically present at your telescope.

    Choosing Your Plate: When to Use the 645mm PLUS Plate

    The PLUS system includes multiple dovetail lengths to suit different setups. This 645mm model is the ideal choice for specific applications where shorter plates are insufficient.

    • Large Telescopes: For heavy or long optical tubes, the 645mm length allows for a very wide separation between support rings, which is critical for preventing mechanical flexure during long exposures.
    • Complex Setups: If you plan to mount multiple accessories like a guide scope, an EAGLE computer, and other devices, the extra length provides the necessary real estate.
    • EdgeHD 8" Automation: The parallel mounting configuration for the ALTO-2 and GIOTTO requires the specific geometry and length of the 645mm plate. Shorter plates will not accommodate this advanced setup.

  • What is the main purpose of the Losmandy style dovetail plate 645mm PLUS?

    Its primary purpose is to securely attach a telescope to a mount that uses a Losmandy-D style clamp. Its 645mm length makes it particularly suitable for large optical tubes or for building complex imaging rigs with many accessories, providing a rigid, flex-free foundation as part of the PrimaLuceLab PLUS system.

    What kind of telescopes is the 645mm PLUS plate best suited for?

    This plate is recommended for large or heavy optical tubes where stability is paramount. The long format allows you to space the tube rings far apart, which significantly improves rigidity. It is also the required plate for specific advanced setups, such as adding the GIOTTO motorized flat generator to a Celestron EdgeHD 8" telescope.

    Can I attach non-PrimaLuceLab rings to the 645mm PLUS plate?

    Yes. While designed to integrate perfectly with PLUS system components, the plate includes a series of central slots. These slots allow you to attach support rings or other mechanical accessories from different brands using standard screws, offering broad compatibility.

    How do I use the 645mm PLUS plate to add a motorized cap to my Celestron EdgeHD 8"?

    You will need to mount the 645mm plate in parallel to your telescope's main tube, on top of the dew shield. This requires the separate PrimaLuceLab PLLSAG925 curved blocks. Once the plate is installed, it provides the mounting point for the ALTO-2 cover motor and the GIOTTO 255 smart flat field generator, creating a fully remote-controlled system for taking flats.

    I have a long refractor. Why would I choose the 645mm PLUS plate over a shorter one?

    For a long refractor, balance and rigidity are critical. A shorter plate forces you to place the support rings closer together, which can lead to flexure, especially when heavy cameras or accessories are attached. The 645mm plate allows for a much wider ring spacing, creating a more stable and rigid connection to the mount that resists sagging and improves tracking and guiding.

    What makes the "PLUS" system different from a standard dovetail plate?

    A standard plate typically only has a few pre-drilled holes. The PrimaLuceLab PLUS system is a complete, integrated ecosystem. Every PLUS component, including this 645mm plate, features a specific pattern of threaded holes and slots that allow you to combine plates, rings, and clamps with maximum rigidity and without needing to drill new holes. It turns a simple dovetail into a modular construction platform.
