The ESATTO 4″ → ARCO 3″ adapter for the Takahashi FSQ-106 telescope (PrimaLuceLab, SKU: PL3600469) enables a quick and rigid connection of the ESATTO 4″ electric focuser with the ARCO 3″ rotator/tilt corrector in the Takahashi FSQ-106 astrograph. CNC machined from a single block of aluminum, the adapter guarantees perfect optical axiality and maintenance of the back-focus budget provided by the manufacturer, thanks to which the whole works without vignetting even on full-frame matrices.

The most important features of the adapter

• dedicated fit: fits only the Takahashi FSQ-106 tube with the ESATTO 4″ extractor
• quick assembly of ARCO 3″ without additional spacer rings
• precisely turned locating surfaces – maintained perpendicularity and axiality
• anodized aluminum 6061-T6 in ESATTO/ARCO color – scratch and corrosion resistant
• short optical length (only 12 mm) – does not “eat up” valuable back-focus
• a set of M4 stainless steel screws ensures a secure, rigid connection
