The ESATTO 2" → Large 3.3" SC Thread Adapter (PrimaLuceLab, SKU: PL3600212 ) allows you to mount the remote-controlled ESATTO 2" focuser on Schmidt-Cassegrain telescopes equipped with a 3.3" (84 mm, 16 TPI) rear thread, such as the Celestron SCT 11"/14" and EdgeHD 925/1100/1400. The aluminum collar has an optical thickness of only 2 mm, so after installation the full back-focus budget required by focal reducers or correctors remains.
