The ESATTO 3" → Takahashi Adapter (M72 × 1 Thread) (PrimaLuceLab, SKU: PL3600245 ) allows the installation of a precise, remote-controlled ESATTO 3" focuser on Takahashi telescopes equipped with an M72 × 1 rear thread (e.g. TSA-120, TOA-130 NS, FS-102, FSQ-85*). The collar screws directly into the tube thread, creating a rigid, on-axis connection with minimal back-focus gain.

The most important features of the adapter

• Thread conversion: M72 × 1 input (Takahashi telescope) → M81 × 1 output (ESATTO 3" front)
• optical thickness < 5 mm – practically no impact on the back-focus budget
• full internal diameter 76 mm – no vignetting for full frame matrices
• CNC milled body made of 6061-T6 aluminum, hard anodized - lightweight, high stiffness and corrosion resistance
• blackened and grooved interior – effective reduction of reflections, improvement of contrast
