The M110 → M92 (female) adapter for ESATTO 4" (PrimaLuceLab, SKU: PL3600316 ) enables the connection of accessories with an M92 × 1 external thread (e.g. reducers, flatteners, rotators) to the ESATTO 4" focuser, whose front thread has a diameter of M110 × 1 . The adapter guarantees an axial, rigid connection and a minimal increase in the length of the optical path, while maintaining full throughput for full-frame sensors.

Key Features

• thread conversion: input M110 × 1 (ESATTO 4") → output M92 × 1 (female)
• optical length of only 7 mm – negligible impact on the back-focus budget
• full internal diameter 92 mm – no vignetting for 24 × 36 mm sensors
• CNC milled body made of 6061-T6 aluminum, hard anodized - lightweight and corrosion resistant
• blackened and grooved interior – effective reduction of reflections, better contrast
