PrimaLuceLab Losmandy Plate 140mm PLUS
The PrimaLuceLab Losmandy Plate PLUS provides a compact and rigid mounting platform for smaller telescopes on mounts accepting a Losmandy D-style plate. Engineered as a core component of the PrimaLuceLab Universal System (PLUS), this plate moves beyond a simple connection, offering a grid of threaded holes and slots to create a fully integrated and modular imaging rig.
A Compact Losmandy Plate for Smaller Telescopes
This Losmandy-style plate is engineered to provide a secure, flex-free connection between your compact telescope and your mount. It's an ideal choice for smaller refractors or other short optical tubes, attaching them firmly to mounts equipped with a Losmandy-D saddle, such as the Sky-Watcher AZ-EQ6 or EQ8.
The PLUS System: A Foundation for Modular Accessory Integration
The defining feature of this plate is its full integration into the PrimaLuceLab PLUS system. Unlike standard dovetails, this plate is covered with a pattern of threaded holes and slots, allowing you to directly bolt other PLUS components like guide rings or support rings onto the plate itself. This creates a mechanically rigid structure, eliminating the flexure common with stacked adapters.
This modularity allows for advanced configurations. By attaching two PLUS dovetail clamps, you can transform this single plate into a robust side-by-side system, perfect for mounting a guide scope parallel to your main imaging telescope on a single mount head.
CNC-Machined Construction: From Solid Aluminum to a Finished Plate
Every PrimaLuceLab PLUS plate is machined with high precision from a single block of aluminum using CNC machines. This manufacturing method ensures maximum rigidity and perfect dimensions. The plate is then sandblasted to achieve a smooth finish and treated with a hard anodizing process to increase surface hardness, protecting it from scratches and corrosion.
PrimaLuceLab PLUS Plates vs. Standard Dovetails: The Integration Difference
A standard dovetail plate serves one purpose: to connect your telescope to your mount. The PrimaLuceLab PLUS plate is designed as the structural core of your entire imaging assembly. Instead of simply being a point of connection, it becomes the hub for all your accessories.
-
Standard Plate Limitation: Attaching accessories often requires additional clamps and plates, which can introduce instability and flexure into the optical train.
-
PLUS System Advantage: Accessories bolt directly to the plate itself, creating a single, solid unit. This improves stability, simplifies cable management, and makes balancing the entire setup more precise.

What size telescope is the PrimaLuceLab Losmandy Plate PLUS for?
This plate is designed for compact telescopes, such as smaller refractors (up to approximately 100mm in aperture) and other short optical tubes that require a stable but not overly long mounting plate.
Will this PrimaLuceLab plate fit my Sky-Watcher AZ-EQ6 mount?
Yes. This plate features a standard Losmandy D-style profile, making it compatible with any mount that uses a Losmandy-D saddle, including popular models like the Sky-Watcher AZ-EQ6 and EQ8.
How is the PLUS plate different from a standard Losmandy plate?
The key difference is the PrimaLuceLab PLUS system. A standard plate typically has only a few holes or a central slot. The PLUS plate features a comprehensive grid of threaded holes, allowing you to directly attach guide rings, support rings, and other accessories to create a single, rigid mechanical structure.
Can I attach guide rings from another brand to this plate?
Yes. In addition to the PLUS-specific threaded holes, the plate includes a series of central slots. These slots are designed to provide compatibility with support rings and guide rings from other manufacturers that use standard screw attachments.
What is the benefit of the anodized finish on the PrimaLuceLab plate?
The hard anodizing process increases the surface hardness of the aluminum. This makes the plate significantly more resistant to scratches from saddle clamps and protects it from oxidation and corrosion, ensuring a long service life.
How can I use this plate to mount my guide scope next to my imaging refractor?
You can convert this plate into a side-by-side system. By purchasing two PrimaLuceLab PLUS dovetail clamps and attaching them to the top of this Losmandy plate, you create two mounting points to hold two telescopes in parallel on a single mount.
