The ESATTO 3.5" LP for SC thread adapter (PrimaLuceLab, SKU: PL3600366 ) allows you to mount an ESATTO 3.5" LP focuser in place of the classic 2″ (2″ × 24 TPI) Schmidt-Cassegrain thread found on the rear plate of popular SCT / EdgeHD / ACF telescopes. This allows you to benefit from precise, automated focusing without the need for permanent tube modifications.

The most important features of the adapter

• thread conversion: SC 2″ (2″ × 24 TPI) → internal M92 × 1 extract ESATTO 3.5" LP
• full internal diameter 86 mm – no vignetting for full frame sensors
• optical thickness < 5 mm – maintaining the back-focus budget of the SCT telescope
• CNC milled body made of 6061-T6 aluminum, hard anodized - high stiffness and corrosion resistance
• internal blackening and grooving – effective reduction of reflections, better contrast
