PrimaLuceLab Losmandy Plate 915mm PLUS
- 915mm Losmandy-style dovetail plate
- Supports optical tubes up to 30 kg
- 13mm thick CNC-machined aluminum construction
- Weighs 2.3 kg
- Part of the modular PrimaLuceLab PLUS system
The PrimaLuceLab Losmandy Plate 915mm PLUS provides a rigid mounting foundation for optical tubes up to 30kg in weight. Its substantial 915mm length and 13mm thickness are machined from a single aluminum block, delivering stability while weighing only 2.3 kg. This design is engineered specifically as a rigid base for large instruments like the Celestron EdgeHD 11" telescope.
Engineered for heavy payloads, this 915mm Losmandy-style plate provides the structural integrity needed for large telescopes. The 13mm thickness, maintained across its entire length, prevents flexure under loads up to 30 kg, ensuring your mount's tracking accuracy is not compromised by a weak mechanical connection. Each plate is CNC machined from a single block of aluminum, then sandblasted and hard-anodized to protect against scratches and oxidation.
This plate is a core component of the Prima Luce Universal System (PLUS), a modular ecosystem of interlocking rings, clamps, and plates. A precise pattern of threaded holes and slots runs along the plate, allowing for the direct, rigid attachment of other PLUS accessories like guide rings or dovetail clamps. This system eliminates the instability of stacked components, creating a single, solid mechanical train from your mount to your guide scope.
A key application for the 915mm plate is creating an upper rail for automating large Celestron SCTs. When paired with optional PLUS curved blocks, you can install this plate in parallel on top of a Celestron EdgeHD 9.25" or 11" optical tube. This provides a rigid platform to mount accessories like the GIOTTO 285 or GIOTTO 320 smart flat field generators and the ALTO-2 telescope cover motor, transforming your setup into a more integrated remote imaging system.
The primary advantage is its integration into the PrimaLuceLab PLUS system. The specific pattern of threaded holes and slots allows for the direct, flex-free attachment of other PLUS components, creating a more rigid and modular setup than a generic plate with only a few mounting holes.
Yes. This is an ideal application. By using the optional PLUS curved blocks to mount the 915mm plate on top of the optical tube, you create a secure platform for attaching automation accessories like the ALTO-2 cover motor and the GIOTTO 320 smart flat field generator.
This plate is designed for optical tubes weighing up to 30 kg (66 lbs). Its 13mm thickness and CNC-machined aluminum construction ensure it can handle large refractors, SCTs, and astrographs without flexure.
The plate includes a series of central slots that are not part of the threaded PLUS pattern. These slots allow you to use standard screws to attach support rings or other accessories from different brands, offering broad compatibility.
While mechanically compatible, the 915mm length is optimized for larger telescopes like 11" SCTs. For an 8" SCT, a shorter PLUS plate (such as a 350mm model) would likely provide better balance and be more manageable without the unnecessary extra length and weight of the 915mm plate.
The curved blocks are adapters required to mount a flat PLUS plate, like this 915mm model, onto the curved optical tube of a Schmidt-Cassegrain telescope. You need them if you plan to attach the plate directly to the top or bottom of a Celestron C9.25, C11, EdgeHD 925, or EdgeHD 1100 OTA.
