PLUS Support Clamps from PrimaLuceLab: Robust and Modular

PrimaLuceLab's PLUS support clamps are high-end accessories designed to securely hold telescopes while offering exceptional modularity thanks to the PLUS (Prima Luce Universal System). These clamps ensure perfect mechanical stability, essential for observation and astrophotography, and make it easy to add additional accessories.

PLUS collar features

• High-precision manufacturing : Machined from aluminum blocks with CNC machines, sandblasted for a smooth finish and anodized for protection against oxidation.
• Rigidity and stability : Designed to eliminate any mechanical bending, ensuring a firm hold on the optical tube, even in heavy or complex configurations.
• Modular design : Equipped with threaded holes (M6) and slots above and below for easy integration with other PLUS system components such as dovetails, plates or guide rings.

Compatibility of PLUS clamps

PLUS collars are available in several sizes to fit different telescopes. Here are the available sizes:

• 80 mm to 95 mm : Ideal for small refractors such as the Takahashi FSQ85 or FC-100DF.
• 100 mm to 125 mm : Suitable for telescopes such as Takahashi FSQ106ED or TSA120.
• 131 mm to 155 mm : Perfect for instruments like the Sky-Watcher Esprit 100ED or Takahashi TOA130.
• 168 mm to 244 mm : Suitable for large telescopes such as the Newton 200 mm or Takahashi TOA150.

Integration with PLUS System

The PLUS system is designed to offer total modularity between all its components. The clamps integrate perfectly with :

• Vixen or Losmandy dovetails: Attach the clamps to a dovetail under the optical tube to mount it to your frame, and add an additional dovetail above the clamps to install accessories such as a guide telescope.
• PLUS guide rings : Mount a small guide telescope directly on the clamps using the special threaded holes.
• Universal plates : Add plates to reinforce mechanical rigidity or attach additional equipment such as cameras or EAGLE units.

PLUS System benefits

• Maximum flexibility : All PLUS system components share standardized dimensions for universal compatibility.
• Scalability : Add or replace components without changing the whole system, even if you modify your configuration in the future.
• Universal compatibility : The central slots can also be used to attach other brands of mechanical accessories.

Application examples

• Attach a main telescope to a mount via a Losmandy dovetail under the collars.
• Mount a guide telescope on guide rings installed above the clamps.
• Add an EAGLE unit between the clamps to centralize IT and electrical management.

What's Included

• Two clamps in the chosen size (e.g. 125 mm).
• A detailed user manual.

Conclusion

PrimaLuceLab PLUS clamps are more than just telescope mounts. Thanks to their modular design and seamless integration with the PLUS system, they offer amateur and professional astronomers alike the opportunity to create customized, stable and scalable configurations. Whether you want to secure your optical tube or add accessories such as a guide telescope, these clamps offer unrivalled strength, precision and flexibility.
