The ESATTO 3" → Sky-Watcher ESPRIT 120 ED / 150 ED adapter (PrimaLuceLab, SKU: PL3600253 ) enables the mounting of a precise, remote-controlled ESATTO 3" focuser in place of the factory focuser of ESPRIT 120 ED and ESPRIT 150 ED apochromats. The collar uses the stock rear cell holes — the installation is fully reversible and the design back-focus of the refractor remains unchanged.

The most important features of the adapter

• dedicated fit for ESPRIT 120/150 ED rear cell – plug-and-play installation without drilling
• maintaining the nominal back-focus of the structure – compatibility with Sky-Watcher flattens and reducers
• full internal diameter 76 mm – no vignetting for full frame matrices
• CNC milled body made of 6061-T6 aluminum, hard anodized - lightweight, stiff and corrosion resistant
• blackened and grooved interior – effective reduction of reflections, better contrast
