ESATTO 3.5" LP Adapter for Large 3.3" SC Thread

This adapter connects the PrimaLuceLab ESATTO 3.5" LP low-profile robotic focuser to Celestron large 3.3" SCT and EdgeHD telescopes (11", 14", 925, 1100, and 1400 models). With an optical thickness of just 2mm, it preserves the ESATTO's minimal profile while maintaining 112mm of backfocus for cameras and accessories, making it ideal for imaging on large aperture SCTs. The adapter features an internal brass compression ring and three locking screws for secure, vibration-free connection of heavy imaging trains.
