The HEQ5 / Sirius EQ-G PLUS adapter plate (PrimaLuceLab, SKU: PLLFLHEQ5 ) allows for quick mounting of PLUS clamps (Vixen + Losmandy) to the Sky-Watcher HEQ5 mount head or its Orion Sirius EQ-G equivalent. This simple upgrade increases the stiffness of the mount's saddle socket and allows the use of both Vixen/GP 45mm and Losmandy D 100mm rails.

The most important features of the adapter

• quick replacement of the standard HEQ5/Sirius EQ-G saddle with any clamp from the PLUS family ( Dovetail Clamp, Big, Maxi )
• full compatibility with Vixen/GP and Losmandy D rails after mounting the PLUS clamp
• 6061-T6 milled aluminum body, hard anodized in red PrimaLuceLab
• precise arrangement of M6 threaded holes (55 mm spacing) – PLUS system standard
• maintaining the central M8 mounting thread – quick assembly without head modification
• minimal weight (~150 g) – no significant impact on the balance of the counterweights
