PrimaLuceLab ESATTO 2" Low Profile Adapter - 3.3" SCT Thread
PrimaLuceLab 3.3" SCT Adapter for ESATTO 2" LP Focuser
The PrimaLuceLab Large 3.3" SC Thread Adapter allows you to connect the ESATTO 2" Low Profile Focuser to a large Celestron SCT (11" and 14") or EdgeHD (925, 1100, and 1400) models with 3.29" rear cells. Since the ESATTO 2" LP has an optical thickness of 32mm and the 3.3” adapter has only 2mm of optical thickness, this leaves 112mm of back focus for your camera and accessories, and that is also the case when used together with the Celestron EdgeHD .7x focal reducers for 925, 1100 and 1400 models.
