  • Observatory Dovetail Clamp Vixen+Losmandy PLUS

    The PrimaLuceLab Observatory Dovetail Clamp Vixen+Losmandy PLUS is engineered to provide a single, robust mounting solution for telescopes equipped with either Vixen or Losmandy-style dovetail bars. This extended observatory-class clamp uses multiple locking blocks to create an exceptionally rigid connection, essential for supporting heavy optical tubes without flexure. As a core component of the PrimaLuceLab PLUS ecosystem, it offers versatile mounting options to replace a stock saddle or build custom side-by-side configurations.

    Universal Vixen & Losmandy Support in a Single Clamp

    This clamp eliminates the need for separate adapters or swapping saddles when you switch between telescopes. The dual-profile design securely grips both the narrower Vixen-style and the wider Losmandy-style dovetails, providing a reliable connection for your entire telescope collection. This universal compatibility makes it an ideal upgrade for any mount, streamlining your setup and takedown process.

    Observatory-Grade Construction for Heavy Payloads

    Designed specifically for heavy instruments, the Observatory Dovetail Clamp is CNC machined from a solid block of aluminum for maximum strength. The entire unit is sandblasted for a smooth finish and then hard-anodized to increase surface hardness and protect against corrosion. This robust construction, combined with a long body and multiple locking points, ensures your heavy telescope remains securely fastened, preventing any shift or flexure during long imaging sessions. Its heavy-duty design does add considerable mass, which must be factored into your mount's total payload capacity.

    Seamless Integration with the PrimaLuceLab PLUS System

    As part of the PrimaLuceLab PLUS (Prima Luce Universal System), this clamp features an array of threaded holes, counterbored holes, and slots. This allows for direct, rigid attachment to other PLUS components like plates, rings, and guiding accessories. This modularity gives you the freedom to build complex, stable imaging rigs. For users with equipment from other brands, central slots provide compatibility for attaching the clamp to non-PLUS plates or rings.

  • What makes the Observatory Dovetail Clamp PLUS different from a standard mount clamp?

    The Observatory Dovetail Clamp PLUS offers three main advantages: dual compatibility with both Vixen and Losmandy dovetails in one unit, an observatory-grade build designed for heavy telescopes, and seamless integration with the modular PrimaLuceLab PLUS system for building custom, rigid setups.

    I have a Vixen bar on my refractor and a Losmandy bar on my SCT. Can the Observatory Dovetail Clamp handle both?

    Yes. The clamp's dual-profile design accepts both Vixen and Losmandy-style dovetails directly without any adapters. This allows you to quickly and securely switch between your different telescopes using the same mount saddle.

    Can I attach the Observatory Dovetail Clamp to a mount from another brand?

    Yes. While it is designed for native integration with the PLUS system, the clamp includes a series of central slots. These allow you to fasten it to plates or mounts from other manufacturers using standard screws, making it a versatile upgrade for almost any setup.

    What is the PrimaLuceLab PLUS system?

    The PLUS system is a complete ecosystem of high-quality, interconnecting mechanical parts for telescopes. It includes:

    • Dovetail Plates (Vixen & Losmandy)
    • Support Rings
    • Guide Rings
    • Dovetail Clamps
    All components are designed with a standardized pattern of holes and slots, allowing you to build rigid and perfectly aligned imaging systems.

    How would I use the Observatory Dovetail Clamp to mount a large Newtonian on my EQ mount?

    For a large Newtonian, you would typically replace your mount's original saddle with the Observatory Dovetail Clamp. Its long contact area and multiple locking blocks provide a much more secure and distributed grip on the dovetail bar than a standard, smaller clamp. This increased stability is crucial for preventing flexure and maintaining collimation with a heavy OTA.

    What is the benefit of the hard-anodized finish on the Observatory Dovetail Clamp?

    The hard-anodizing process creates a protective layer on the aluminum that is much harder and more durable than standard anodizing or paint. This provides superior resistance to scratches, wear, and corrosion from dew and humidity, ensuring the clamp maintains its structural integrity and appearance over years of use.
