The ESATTO 2" → SC 2" (24 TPI) thread adapter (PrimaLuceLab, SKU: PL3600209 ) allows you to screw your ESATTO 2" remote-controlled focuser directly into Schmidt-Cassegrain telescopes with a standard SC rear thread, such as the Celestron C6, C8, C9.25 or EdgeHD 800. The adapter does not add any optical length, so you retain the full back-focus budget provided by the tube manufacturer.

The most important features of the adapter

• thread conversion: input SC 2" (24 TPI) → output M56 × 1 (front ESATTO 2")
• no additional optical length – ESATTO 2" retains its 67 mm back-focus
• full internal diameter 50.9 mm – no vignetting for APS-C sensors
• CNC milled anodized aluminum - lightweight and corrosion resistant
• dedicated to SCT 6", 8", 9.25" and EdgeHD 800
