The ESATTO 3" → Meade 16″ (4″ rear thread) adapter (PrimaLuceLab, SKU: PL3600292 ) allows you to replace the original focuser in your large Schmidt-Cassegrain Meade 16″ telescope with a precise, automated ESATTO 3" focuser. The adapter screws directly into the 4″ rear thread of the tube, creating a rigid and axial connection with minimal back-focus increment.

Key Features

• thread conversion: 4″ SCT input (telescope) → M81 × 1 output (ESATTO 3" front)
• full 76mm internal diameter – no vignetting for full frame sensors
• optical thickness < 5 mm – maintaining the nominal back-focus of the SCT system
• CNC milled body made of 6061-T6 aluminum, hard anodized - high stiffness and corrosion resistance
