Losmandy style dovetail plate 495 mm PLUS (PrimaLuceLab, SKU: PLLLOS495P ) is a long 4″ mounting plate (Losmandy D) designed to stably mount medium and heavier telescopes on Losmandy clamps. CNC milled from a single block of 6061-T6 aluminum and hard-anodized, it provides high rigidity, and the modular hole pattern of the PLUS system allows for easy addition of tube clamps, guides or EAGLE accessories without drilling new holes.
• Losmandy D standard – 100 mm wide, compatible with EQ8, CGX-L, GM2000, AZ-EQ6 (with Losmandy adapter) and many others
